Abstract The high-pressure Heilongjiang Complex records a long and complicated evolution from the late Paleozoic to Mesozoic in NE China, which is still subject to controversy. In this paper we present a new detailed study including structural, geochemical and geochronological analyses (Ar-Ar dating on metamorphic minerals, U-Pb SIMS dating on zircons). Two main periods of oceanward accretionary growth are identified between 305 Ma and 195 Ma and around 112 Ma-101 Ma. These periods of accretionary growth were associated with the emplacement of voluminous magmatism, slab roll-back with continental back-arc extension, and growth of a forearc accretionary prism. Between these periods of accretionary growth, a major phase of regional subduction erosion took place between 195 Ma and 142 Ma at the eastern edge of the Songliao Block. The main effects of this subduction erosion phase were that regional Jurassic-early Cretaceous extrusion overlapped with
Mesozoic accretion and erosion in NE China, which disturbed the initial orogenic
architecture. With a review of relevant zircon ages of this accretionary orogen, we unravel the complicated geodynamic history of accretion, subduction erosion and tectonic extrusion that shaped NE China from the late Paleozoic to Mesozoic.

1. Introduction Accretionary orogens have long been regarded as important records of the accretionary history of active margins (Şengör et al., 1993; Windley et al., 2007; Isozaki, et al., 2010; Wilhem et al., 2012; Wakita et al., 2013; Xiao et al., 2015). However, the traditional understanding of the uni-directional oceanward growth of accretionary complexes was challenged by the recognition of successive phases of tectonic erosion in the Japanese Islands (Isozaki et al., 2010; Suzuki et al., 2010; Maruyama et al., 2011). This particular tectonic process may be related to the subduction of a mid-oceanic ridge (Windley and Xiao, 2018), which led to the destruction and fragmentation of most peri-Pacific orogens and as consequence it contributed to the removal of much continental crust (Scholl and von Huene, 2009; Yamamoto, 2010). A tectonic erosion process is highlighted by the presence of serpentinite mélange belts, which include fragments of the upper plate and HP rocks from the exhumed subduction channel during landward retreat of the magmatic front. This event led to subduction of huge quantities of upper plate material (fore-arc basins, accretionary complexes, magmatic arcs) into the mantle. A phase of accretionary growth occurred between two events of tectonic erosion marked by oceanward addition of accreted ocean floor material, terrigenous trench sediments, island arcs, and oceanic plateaus (Maruyama et al., 2011; Suzuki et al., 2010), accentuated by episodic arc-arc collisions (Xiao and Santosh, 2014). Another significant process shaping subduction--accretion orogens is “arc-slicing” or “arcshaving” faulting, which cause the repetition of accretionary complexes and magmatic arcs, which clearly change the primary crustal architecture (Natal’in and Şengör, 2005). The subduction-accretion processes of the Paleo-Pacific orogen in NE China are marked by the development of Mesozoic accretionary complexes, magmatic provinces and regional ENE-
3
NE transcurrent faults (Liu et al., 2017; Wu et al., 2011; Xiao et al., 2015). There is a range of conceptual models proposed to explain the geodynamic evolution of this orogen (Ma et al., 2017; M.D. Sun et al., 2018; Zhou et al., 2014), but the mechanisms of subduction-accretion-extrusion remain poorly understood. To fill the gap, we propose to focus on the HP (blueschist) Heilongjiang Complex, which belongs to the Mesozoic accretionary, Jilin-HP Heilongjiang belt, which is bound by the Zhangguancai Range magmatic arc (Songliao Block) to the west and the Jiamusi Block to the east (Wu et al., 2007; Zhou et al., 2009; Zhu et al., 2017d). The high-pressure Heilongjiang Complex is located along the N/S-trending Mudanjiang fault, which is an important suture between the Jiamusi and Songliao Blocks (Zhou et al., 2009, 2013). Its tectonic evolution remains controversial; different studies have suggested that the high-pressure Heilongjiang Complex is an Archean greenstone belt (Liu, 1988; Zhao et al., 1996), a late Proterozoic metamorphic belt (Dang and Li, 1993), or a Triassic northeasterly extension of the Dabie-Sulu-Yanji HP-UHP belt (Ishiwatari and Tsujimori, 2003; Oh, 2006; Zhang, 1997, 2004). Other studies suggested that the Complex is a late Ordovician mélange that formed on the eastern margin of the CAOB, and was followed by mid-Silurian or Carboniferous collision (Li, 2006; Liou et al, 1989a, 1989b; Wang et al., 2016; Zhang, 1992; Zhang et al., 2018). Recent advances, however, indicate that the high-pressure Heilongjiang Complex is a Mesozoic accretionary complex that marks the transition between the closure of the Paleo-Asian Ocean in the west and the start of westward Paleo-Pacific subduction in the east (Wu et al., 2007; Zhou et al., 2009, 2010; Zhou and Li, 2017; Zhou and Wilde, 2013). The Complex represents a narrow seaway that opened between 260 Ma and 210 Ma as a consequence of slab-roll back of the Pacific oceanic plate, which involved a change in orientation of its motion. In this model the closure of the narrow oceanic basin at about 210-180 Ma (Zhou et al., 2009, 2010; Zhou and Wilde, 2013), or even after 140 Ma (Zhu et al., 2015, 2017a, 2017b, 2017c, 2017d) gave rise to the exhumation of the high-pressure 4
Heilongjiang Complex. However, Yang et al. (2017, 2019) considered that the presence of subduction-related mafic rocks in the HP Heilongjiang Complex, the difference of Permian sedimentary sequences, and the crustal difference between the western and eastern margins of the Jiamusi Massif, all mitigate against a Permian rift model between the Jiamusi and Songliao blocks. Ge et al. (2016, 2017, 2018) suggested that a wide ocean named the “Mudanjiang Ocean” existed between the Songliao and Jiamusi Blocks and was closed after 140 Ma from south to north in a scissor-like manner during an oblique convergence, which gave rise to left-lateral movements along the suture zone The direction of amalgamation was considered to be only westward, thereby producing Permian to late Jurassic arc magmatism between 275 Ma and 140 Ma in the Zhangguancai range magmatic arc (Ge et al., 2017, 2018; Zhu et al., 2017d), but an alternative model was proposed with a double-side subduction of the Mudanjiang Ocean between the composite Bureya–Jiamusi–Khanka Block and the Zhangguancai range magmatic arc in the late Palaeozoic-early Mesozoic (Dong et al., 2017a, 2017b, 2018a, 2018b). Finally, Aouizerat et al. (2018) proposed that the HP Heilongjiang Complex developed in an E/W-directed Pacific subduction regime between 190 Ma to 160 Ma, and the final uplift was in the end-Jurassic between 160 Ma and 140 Ma as a result of N-S-directed shortening related to closure of the Mongol-Okhotsk Ocean In this paper we present new geochemical analyses and U-Pb SIMS dating of zircons in volcanic and granitic rocks coupled with
40Ar-39Ar
phengite and SIMS U-Pb zircon dating of
blueschists located in the HP Heilongjiang Complex and on the eastern edge of the Zhangguancai Range magmatic arc. Structural analyses demonstrate the interactions between the HP Heilongjiang Complex and the regional ENE/NE-trending wrench faults. We combine all these data with a review of zircon ages from the whole accretionary orogen in NE China. A spatial grid of intrusive and extrusive ages shows the migration of a magmatic front during the Paleozoic to Mesozoic eras. 5
All the data are critically evaluated to propose an innovative model of tectonic erosion, accretionary growth and extrusion that controlled the evolution of the Paleo-Pacific orogen in NE China from the late Paleozoic to Mesozoic.
2. Geological setting In NE China, three orogenic belts evolved simultaneously in Paleozoic to Mesozoic times: (1) the E-striking Central Asian Orogenic Belt (CAOB), also named eastern Altaids (Mossakowsky et al., 1994; Şengör et al., 1993; 1996; Wilhem et al., 2012); (2) the WSW/W-striking MongolOkhotsk belt in the north (Parvenov et al., 2003) and (3) the N-striking Paleo-Pacific belt in the west (Aouizerat et al., 2018; Wu et al., 2007; Xu et al., 2013; Zhou et al., 2014). The eastern part of NE China was mainly developed during the Mesozoic subduction of the paleo-Pacific plate together with accretion of micro-continents such as the Jiamusi-Khanka-Bureya Blocks and the CAOB blocks to the west (Fig. 1a). Exposed tectonic units include Mesozoic accretionary complexes (Jilin-Heilongjiang HP belt, ophiolitic Nadahanda terrane), which extend from the Russian Far East (Sikhote-Alin terrane) and central Japan (Mino-Tamba terrane) (Liu et al., 2017; Wu et al., 2011; Zhou et al., 2014). The whole orogenic system is divisible into the following units: 1) the Jiamusi block, 2) the Heilongjiang HP complex in the center, and 3) the Zhangguancai Range magmatic arc in the west.
2.1 Blocks The Jiamusi block or massif is a tectonic unit about 36 km thick (Xing et al., 2018) bound by the N-directed Mudanjiang Fault in the west, and the ENE-directed Dunhua-Mishan Fault in the south (Ma et al., 2017; Zhou and Li, 2017). The Khanka and Bureya massifs near the NE ChinaRussian Far East border are considered to be attached to the Jiamusi Massif, and thus have been
6
referred to as a composite Khanka-Jiamusi-Bureya block (Fig. 1b; Wilde et al., 2000, 2003). However, their mutual affinity is questioned based on the similar Paleozoic to Mesozoic magmatic history of the Khanka massif and the arc magmatic complexes of the Zhangguancai Range magmatic arc (K. Liu et al., 2018). The basement rocks of the Jiamusi Massif consist of the Mashan complex, a khondalitic metasedimentary belt composed of felsic granulites, marbles, and graphitic schists that were metamorphosed at around 500 Ma (Wilde, 2001, 2003; Wilde et al., 2000). The Mashan complex is spatially associated with coeval strongly deformed, early Paleozoic granitoids dated by LA-ICP-MS and SHRIMP U-Pb zircon methods between 540 and 488 Ma (Bi et al., 2014; Wilde et al., 1997; 2000, 2003; Yang et al., 2014; Table 1). Permo-Triassic volcanic and granitic rocks intruded the Mashan complex (302 Ma and 204 Ma, U-Pb zircon ages; Bi et al., 2017a; Dong et al., 2017b, Long et al., 2019; Wu et al., 2011, Yang et al., 2017-Table 1). Granitic gneisses located in the western edge of the Jiamusi Massif are dated between 267 and 254 Ma (U-Pb zircon; Wu et al., 2001). A recent spatial analysis of these late Carboniferous to Triassic magmatic rocks highlights a westward younging trend from 275 Ma to 245 Ma (Yang et al., 2019). According to recent studies, the eastern edge of the Jiamusi Block was a passive margin from 380 to 310-305 Ma, while westward subduction started to develop in the Jiamusi Massif and late CarboniferousTriassic magmatic rocks were emplaced around 302 Ma (G.Y. Li et al., 2019; Yang et al., 2019). The tectonic setting of these late Carboniferous-Triassic magmatic rocks could be related to: 1) late Carboniferous to middle Permian Paleo-Pacific subduction (Bi et al., 2015, 2016, 2017a, 2017b; M.D. Sun et al., 2015), 2) Paleo-Asian Ocean-related subduction associated with the collision between the Jiamusi and Khanka blocks (Meng et al., 2008; Xu et al., 2012) or 3) westward-directed subduction of the Mongol-Okhotsk ocean (G.Y. Li et al., 2019; Zhou and Li, 2017).

The eastern part of the Songliao Block is bound by the N- to NNE-trending Zhangguancai magmatic arc (Fig. 1b), which is composed of Paleozoic and Mesozoic intrusive rocks, Neoproterozoic–early Paleozoic and late Paleozoic volcano-sedimentary rocks, and voluminous Mesozoic– Cenozoic volcanic units (HBGMR, 1993; Wang et al., 2015; Wang et al., 2017; Wu et al., 2011). The first magmatic rocks are represented by granitoids that have LA-ICP-MS U-Pb zircons ages between 516 Ma and 425 Ma (Wang et al., 2012, Wang et al., 2016, 2017; Wu et al., 2011; Table 3). The second magmatic rocks have LA–ICP–MS zircon U–Pb ages from 366 Ma to 286 Ma (Guo et al., 2018; Meng et al., 2011). The third and youngest magmatic event (271 Ma to 166 Ma event; Table 2) is considered to reflect either the closure of the Paleo-Asian Ocean (Guo et al., 2016; Xu et al., 2009, 2013) or an active margin setting related to subduction of the PaleoPacific ocean (Feng et al., 2018; Ge et al., 2018; K. Liu et al., 2019; Qin et al., 2018; Tang et al., 2011; Wu et al., 2011; Yang et al., 2015, Yu et al., 2012, 2013; Zhao et al., 2018; Zhu et al., 2017d). Recent studies suggest a progressive migration of the Permo-Jurassic magmatic front from the west (201–198 Ma) to the east (186–182 Ma) (Feng et al., 2018), although a westward younging trend from ~200 Ma to ~174 Ma was proposed by Ge et al. (2017).
2.2 Oceanic and accretionary materials The Heilongjiang blueschist belt forms the central part of the Jilin-Heilongjiang-HP belt (Wu et al., 2007; Zhou et al., 2009; Zhou and Li, 2017) (Fig 1b), which is characterized by a blockin-matrix mélange that consists of blueschist and serpentinite blocks within a metasedimentary matrix of metapelites, quartzites and marbles (Wu et al., 2007; Zhou et al., 2009, 2010; Aouizerat et al., 2018). The blocks consists of amphibolite facies meta-gabbros, meta-gabbro-diorites, metadiorites, meta-andesites, granitic gneisses, monzo-granite gneisss, and dioritic gneisses (Cui et al., 2013; Dong et al., 2017a, 2018a, X.P. Li et al., 2010; Wu et al., 2007; Yang et al., 2019; Zhou et
8
al., 2010). The protoliths of the metabasites (blueschists, greenschists, and amphibolites) were alkaline and tholeiitic basalts with E-MORB and OIB affinities, indicative of rift and ocean island settings (Ge et al., 2016, 2017; Zhou et al., 2009, 2010; Zhu et al., 2015, 2017a, 2017b). The protoliths of the micaschists were shales, mudstones and tuffs (Cao et al., 1992; Wu et al., 2007). The serpentinite protoliths were dunites, lherzolites and harzburgites (Wu et al., 2007). The geochemistry of the metamorphosed gabbros, gabbro-diorites, diorites and andesites is interpreted to reflect a volcanic-arc setting (Dong et al., 2017a, 2018a; Yang et al., 2019), whereas from their geochemistry the monzogranitic and alkali-feldspar granitoids were considered to have syncollisional affinities (Cui et al., 2013). In the Mudanjiang area, the peak P–T conditions of the blueschists were estimated at 320– 180°C and 8–16 kbar (Zhao et al., 2011), whereas the peak P–T conditions of the amphibolites were calculated as 10.9 kbar and ~622°C (Ge et al., 2017). Peak P–T conditions of blueschists in the Yilan area are 9–11 kbar at 320–450°C (Zhou et al., 2009,) whereas peak P–T conditions of the amphibolites are 10–13 kbar at 500–580°C (W. Li et al., 2010, 2019; Table 3). Some SHRIMP and LA-ICP-MS U-Pb zircon ages suggest that the protoliths of the blueschists and amphibolites formed between 308 Ma to 195 Ma (Dong et al., 2019; Ge et al., 2016, 2017; Zhou et al., 2009, 2010, 2013; Zhu et al., 2015). However, recent LA-ICP-MS U-Pb zircon dates of mafic blueschists and greenschists in the Yilan area give younger weighted mean U-Pb ages of 162 Ma to 142 Ma (Zhu et al., 2015, 2017a). Most LA-ICP-MS and SHRIMP zircon U-Pb dates of meta-igneous rocks give ages ranging from 263 Ma to 211 Ma (Cui et al., 2013; Dong et al., 2017a, 2018b, Han et al., 2019; X.P. Li et al., 2010; Yang et al., 2019; Zhou et al., 2010) with local early Paleozoic ages of ca, 492 Ma in the gneisses (Han et al., 2019; Zhou et al., 2010; Table 4). These protolith ages can be linked to the regional Permian magmatism and the adjacent Mashan
9
Complex, which indicates incorporation of early Paleozoic granitic components into the accretionary complex (Zhou et al., 2010). The timing of deposition of the metasediments (your use of the word 'formations' is not correct) is constrained by LA-ICP-MS and SHRIMP U-Pb dates on detrital zircons that have a youngest age peak at 200 Ma (Ge et al., 2016; Li et al., 2011; Zhou et al., 2010). However, recent dates of detrital zircons have a youngest peak of 186-167 Ma suggesting that the latest depositional age of these metasediments could not be as young as 180-170 Ma (Dong et al., 2018a; Zhu et al., 2017c; Table 4). The age of metamorphism was determined by numerous radiometric Rb-Sr, ArAr and SIMS U-Pb dating of metamorphic minerals and can be subdivided into two main time ranges: 198–170 Ma and 165–140 Ma (Aouizerat et al., 2018; Dong et al., 2019; Table 5) with most radiometric ages between 180 Ma and 170 Ma.
3. Field geology 3.1 Heilongjiang complex: metamorphic rocks and structures 100 meter-size serpentinite blocks are mostly observed in the western Yilan area; there are only a few occurrences in the east (Fig. 2a). Locally, quartz and calcite veins occur in tectonic breccias, and serpentinite blocks show multiple cleavage fabrics associated with slicken-fibres. Close to Yilan city massive metagabbros that display textures with weak gneissic fabrics (Dong et al., 2017a) are associated with amphibolitic gneisses (Fig. 2a). There are amphibolite-rich 10 to 100 mete-size blocks and boudins in the western Yilan area and 100-meter-sized amphibolite blocks in the eastern Yilan area (Aouizerat et al., 2018; Fig. 2a). Blueschists mostly occur in the central and eastern Yilan area (Aouizerat et al., 2018; Fig. 2a and 3a). The blueschists form either blocks and thick sheets or thin layers and boudins intercalated with metapelites and mafic greenschists (Aouizerat et al., 2018; Zhou et al., 2009,
10
2010; Zhu et al., 2015, 2017a, 2017b). The metasediments are mostly micaschists alternating with 10-100 meter-wide layers of quartzite and marbles (Aouizerat et al., 2018; Fig. 2a). In the Mudanjiang area 100 meter-long blueschist lenses alternate with micaschist and amphibolite lenses (Fig. 2b) and 10 cm to 1 m-wide (or long?) stretched pillows occur inside blueschist lenses (Zhao et al., 2010; Zhou et al., 2009; Fig. 3b). The amphibolite lenses are intruded by meter-wide granitic and granodioritic veins near the village of Modaoshi. Quartzo-felspathic layers alternate with strongly altered amphiboles, which together define a schistosity within the veins (Fig. 2b; Fig. 3c and d). Structural analysis of metamorphic rocks, poorly exposed in the HP Heilongjiang Complex, were undertaken in order to further constrain the structural correlations between the HP Heilongjiang Complex and the ENE-NE-directed transcurrent faults that cross-cut NE China. For a detailed analysis of the structures in the Yilan area, the reader is referred to Aouizerat et al. (2018). In the southern Yilan area, the foliation mostly strikes E-W and dips moderately south. In the northwest, the foliations strike E-ENE, and dip steeply to the N-NNW. In the northeast Yilan area the trend of the foliation rotates counter-clockwise toward the NE along the NE-trending Yilan-Yitong fault, and it plunges steeply to the NW (Fig 2a; Fig. 3e). Mineral lineations in the blueschists are defined by aligned glaucophane and chlorite-quartz-phengite aggregates. In the Mudanjiang area, the foliation strikes ENE and dips gently NNW. The associated mineral lineation plunges gently north and is defined by aligned glaucophanes and epidotes (Fig 2b; Fig. 3f).
11
3.2 Granitoids and volcanic rocks associated with the Heilongjiang Complex 3.2.1 Granitoids Along the Yilan-Yitong fault in the northwest Yilan area there is a leucogranite, which has a granular texture with subhedral quartz (45-50 %), plagioclase and alkali felspar (45-50%), biotite (<5 %) and minor apatite, titanite and zircon (Fig. 2a; Fig. 4a and b). Close to the leucogranite in the Yilan-Yitong fault is a kilometre-long monzodiorite (Fig. 2a; Fig. 4 b and c), which has a granular texture with subhedral hornblendes (40%), plagioclase feldspar (50 %), biotites (>5%), and rare minute grains of pyroxene (5-%).
3.2.2 Volcanic rocks and dykes In the eastern Yilan area a 10 kilometer-long trachytic lava, which intrudes the HP Heilongjiang Complex, displays a trachytic texture with subhedral to anhedral saussuritized alkali -feldspars (50 %), biotites (20-30 %) and amphiboles (> 15-10 %) (Fig. 2a; Fig. 4e and f). The blueschist blocks in the Heilongjiang mélange in the east Yilan area are intruded by a leucogranitic dike, which displays a porphyritic texture with subhedral feldspars (30 %) and strongly altered biotites (10 %) surrounded by a matrix of feldspars, opaques, quartz and altered biotites (Fig. 2a, Fig. 4g and h).
3.3 Eastern edge of the Zhangguancai Range magmatic arc: gabbros and leucogranites In the south of the Yilan area near Yongshuncun village (Fig. 2c) along the eastern edge of the Zhangguancai Range magmatic arc, gabbros and leucogranites are transected by ESE-, SE- and NW-trending extensional faults. Inside the leucogranites 10 cm-scale stretched lenses of gabbro contain alternating elongate feldspar and amphibole minerals that define an ENE-directed sub12
horizontal foliation plane (Fig. 5a, b and c). The gabbros are composed of plagioclase (50–70%), clinopyroxene (15–25%), amphibole ( ≤ 5%), interstitial Fe-Ti oxides (0–5%), and accessory zircons and apatites (Fig. 5d).
4. Sampling We collected representative magmatic and metamorphic rocks from the Heilongjiang Complex and from the eastern edge of the Zhangguancai Range magmatic arc in order to determine the different periods of accretion and erosion in NE China. We undertook radiometric dating integrated with geochemical analyses of the representative magmatic and metamorphic rocks. Along the eastern edge of the Zhangguancai Range magmatic arc near Yongchunsun village in the south of the Yilan area, a gabbro was sampled for U-Pb SIMS dating of zircons (Yil-GAB16 sample). Trace and major element analyses were also performed on this gabbro sample to help understand its tectonic origin. Inside the HP Heilongjiang complex, U-Pb SIMS dating and trace and major element analyses were undertaken on a blueschist located in the eastern Yilan area (Yil-BLUE-19 sample) and on a leucogranite (YIL-LEU-14 sample) from the northwestern Yilan area in order to constrain their protolith ages, tectonic setting and timing of incorporation in the HP Heilongjiang Complex. To constrain the time of metamorphism that affected the HP Heilongjiang Complex, phengite-bearing-blueschists (MUD-31 and MUD-39), granitic and granodiorite veins that intruded the amphibolitic lenses (MUD-37 and MUD-40) from the Mudanjiang area were dated by Ar-Ar and U-Pb SIMS on zircons respectively. Major and trace element geochemical analyses were carried out on these granitic and granodioritic veins to constrain their source compositions.
13
Different types of post-accretionary magmatic rocks, which intruded the HP Heilongjiang Complex, were further dated by the U-Pb zircon SIMS method. These post-accretionary rocks from the eastern Yilan area include a trachyte (Yil-T-2); and a leucogranitic dike (Yil-LEU-23), which crosscuts (a trachyte, like all lavas, cannot 'intrude' anything) a blueschist. A monzodiorite (YILG-15) in the northwestern Yilan area was included in this data-set. Major and trace element geochemical analyses and U-Pb dating were conducted to better understand the tectonic settings of these rocks.
5. Analytical methods 5.1 Zircon U-Pb Dating U-Pb isotopes of zircon were analyzed on a Cameca 1280 SIMS at the Institute of Geology and Geophysics, Chinese Academy of Sciences in Beijing. The reader is referred to Li. X.H et al (2009) for more detailed instrumental descriptions and analytical procedures. During the analyses, the zircon standard Plesovice (206Pb/238U age = 337 Ma) (Sláma et al., 2008) was used for the Pb/U calibration, and the zircon standard 91500 (Th = 29 ppm, and U = 81 ppm) (Wiedenbeck et al., 1995) was used to calibrate the U and Th concentrations. Thus, a long-term uncertainty equal to 1.5% (1 RSD) for
206Pb/238U
measurements of the standard zircons was propagated to the
unknowns (Q.L. Li et al., 2010). The corrections are considered sufficiently weak to be insensitive to the choice of common Pb composition. Based on the assumption that the common Pb is largely surface contamination introduced during the sample preparation, an average of present-day crustal composition (Stacey and Kramers, 1975) is used for the common Pb. The software Isoplot/Ex v. 2.49 program was used to reduce the data (Ludwig, 2001). Uncertainties of individual analysis are displayed at a 1σ level; Concordia U-Pb ages are quoted with a 95% confidence interval.

5.2 Whole-rock major and trace element analyses Major and trace element whole-rock analyses of sampled intrusive and volcanic rocks were performed at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) of Beijing; the results are presented in Table 7. Major oxide abundances were determined by X-ray fluorescence (XRF) spectrometry using a Shimadzu XRF1500 sequential spectrometer. The analytical uncertainties range from 1% to 5%. Trace-element abundances were measured by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) with a Finnigan MAT Element spectrometer. Based on the Chinese national standards GSR-1and GSR-2, the error was below 5% for trace elements with concentrations above 10 ppm and below 10% for trace elements with concentrations below 10 ppm (Ding et al., 2017). The reader is also referred to Gao et al. (2002) for a more detailed descriptios of the trace element analytical procedure.
5.3 Phengite Ar-Ar dating Phengites were selected from blueschist lenses located near Modaoshi village (i.e Mudanjiang Area, see Fig. 2b for location). 40Ar‐39Ar dating was performed in the Noble Gas laboratory of the School of Earth Sciences at the University of Montpellier 2, France, with a new generation multicollector mass spectrometer (MS). The reader is referred to Wu et al. (2017) for a detailed description of the analytical procedure. The ArArCALC 2.4 software was used to calculate the plateau ages (Koppers et al., 2002) that are reported with a 2σ uncertainty, including an uncertainty in the J-value.

6. Results 6.1. Blueschist (YIL-BLUE-19 sample) 6.1.1. Zircon U-Pb dating The zircon SIMS results are presented in Table 6. The zircons show a prismatic shape and they are colorless and transparent. The length/width ratios of the chosen zircons are between 1:1 and 2:1. In cathodoluminescence images a clear oscillatory zoning cannot be observed for most of the zircon grains. The analyzed zircons display uranium contents (2489-287 ppm) different from thorium (2938-117 ppm) and lead (462-24 ppm) contents, with Th/U ratios ranging from 0.17 to 1.86. Accordingly, these Th/U ratios above 0.1 indicate a magmatic origin for all these zircons (Hoskin and Schaltegger, 2003). Seven concordant zircons were analyzed among which the two oldest yield
207Pb/206U
zircon ages of 2489.5±9.3 Ma and 1588.5±15.3 Ma. Additional five
concordant 206 Pb / 238U zircon ages are recorded at 958±13.4 Ma, 919.2±12.9 Ma, 426.6±11.8 Ma, 416.4±6.1 Ma and 355.8±5.2 Ma, respectively. Thus, we interpret the youngest concordant 206Pb/238U
zircon age of 355.8±5.2 Ma as the time when the youngest inherited or xenocrystic
zircon was incorporated into the evolving basaltic magma; accordingly, this basaltic rock was likely emplaced coevally at after 355.8±5.2 Ma. We therefore presume that the 356 Ma zircon age may represent the maximum time of emplacement of the host-rock (Fig. 6a).
6.1.2. Whole-rock geochemistry of major and trace elements The blueschist sample YIL-BLUE-19 has an ultramafic-mafic composition (SiO2 = 43.43 wt. %; TiO2 = 3.53 wt. %; Na2O =2.13 wt. %; Al2O3 =13.34. %; Fe2O3 = 13.88 wt. %; CaO = 8.84 wt. %; K2O = 3.64 wt. %, and MgO = 4.84 wt. % with a Mg# of 33) (Table 7). The contents of Ni, Cr, and Cu are respectively: 52.9 ppm, 34 ppm and 41.4 ppm. The MgO versus SiO2 diagram (Le Bas, 2000) and Zr/TiO2 (×10-4) versus Nb/Y diagram (Winchester and Floyd, 1976) indicate that
16
the blueschist Yil-BUE-19 sample is compositionally an alkali basalt (Fig. 10). The trace element compositions of the basalt indicate a very strong REEs abundance (ΣREEs = 318 ppm) with high LREEs/HREEs (5.6) and (La/Yb)N (26.7) ratios and no Eu anomaly (δEu = 1.0). The chondritenormalized REE diagram (Sun and McDonough, 1989) shows a right-decreasing REE pattern, a strong enrichment in LREEs, and depletion in HREEs (Fig. 12a). The primitive mantle normalized spider diagram (Sun and McDonough, 1989) is characterized by an enrichment in LILEs (e.g. Cs, Rb, Ba) and HFSEs (e.g. Ce, La, Zr, Hf, Ti, Nb, Ta) with a strong positive anomaly in Cs and a weak negative anomaly in Sr (Fig. 11b). The Nb/Yb, Th/Yb and Ta/Yb ratios have respective values of 29.6, 2.7 and 2.0 (Table 7).
6.2. Leucogranite (Yil-LEU-14) 6.2.1. Zircon U-Pb dating The zircon SIMS results are presented in Table 6. The selected zircons are prismatic, colorless and transparent, their length/width ratios are between 3:1 and 2:1, and in cathodoluminescence images most grains show clear oscillatory zones. In analyzed zircons the contents of uranium (2233-1673 ppm) are higher than thorium (214-104 ppm) and lead (71-95 ppm), and their Th/U ratios range from 0.06 to 0.10; accordingly, these low Th/U ratios < 0.1 indicate a metamorphic origin (Hoskin and Schaltegger, 2003). Seven analyzed zircons have concordant
206Pb/238U
zircon ages ranging from 251.23 ± 3.7 Ma to 235.29 ±3.5 Ma with a
weighted mean age of 245.5 ±3.9 Ma. Consequently, the weighted mean 206Pb/238U zircon age of 245.5±3.9 Ma is interpreted as the crystallization time of these metamorphic zircons (Fig 6b). Thus, we consider that these zircons were inherited and incorporated in the magma and crystallized during a 245 Ma metamorphic event. Accordingly, the 245 Ma zircons likely represent the maximum age of the leucogranite.
17
6.2.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for the leucogranite (Yil-Leu-14 sample) are given in Table 7. The leucogranite has contents of SiO2 78.52 wt %, Na2O 3.63 wt %, K2O 4.07 wt % and MgO 0.11 wt% and a Mg# of 28. The Ni and Cu values are respectively 2.1 ppm and 2.6 ppm. The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) shows that this is high-K calc-alkaline leucogranite (Fig. 11a and c). It has a weak total abundance of REEs (ΣREE = 4.3 ppm), weak LREEs/HREEs (= 4) and (La/Yb)N (=2.6) ratios, a strong positive Eu anomaly (δEu = 11.6), and high concentrations of Sr (325 ppm) and Sr/Y ratio (308). The chondrite-normalized REE pattern (Sun and McDonough, 1989) shows a weak, but prominent, enrichment in LREEs and a depletion in HREEs (Fig. 12c). A primitive mantle-normalized spider diagram (Sun and McDonough, 1989) demonstrates an enrichment in LILEs (e.g. Cs, Rb, Ba, and Sr), a strong depletion in HFSEs (e.g. Nb, Ta, La, Ce, Nd), and strong positive anomalies of Pb, Zr and Hf (Fig. 12d).
6.3. Gabbro (Yil-GAB-16) 6.3.1. Zircon U-Pb dating The zircon SIMS results for this gabbro are presented in Table 6. The chosen zircons are prismatic, colorless and transparent, have length/width ratios between 1:1 and 2:1, and in cathodoluminescence images clear oscillatory zones are not always present. The analyzed zircons have contents of uranium (2611-457 ppm), thorium (2322-319 ppm), and lower lead (116-26 ppm), and Th/U ratios range from 0.33 to 1.00; accordingly, these Th/U ratios > 0.1 indicate these zircons are magmatic (Hoskin and Schaltegger, 2003). 40 analyzed zircons have concordant zircon ages from 215.8±3.2 Ma to 195.5±2.9 Ma with a weighted mean
206Pb/238U
206Pb/238U
age of 211±1
Ma. Consequently, this age of 211±1 Ma is interpreted as the time of crystallization of these magmatic zircons and their host gabbro (Fig. 6c).
18
6.3.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for the gabbro are presented in Table 7. The gabbro contains 46.70 wt. % SiO2, 1.09 wt. % Na2O, 0.31 wt. % K2O, and 6.55 wt. % MgO, and has a Mg# of 70. Ni, Cr, and Cu contents are respectively 54.6 ppm, 265 ppm and 18.8 ppm The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) shows that this is a calc-alkaline gabbro (Figs. 11a and c). It has a low total REE abundance (ΣREEs = 12.5 ppm), moderate LREEs/HREEs (=5.8), a strong (La/Yb)N (=7.18) ratio, a positive Eu anomaly (δEu = 2.0), a high concentration of Sr (835 ppm) and a high Sr/Y ratio (286). The chondrite-normalized REE diagram (Sun and McDonough, 1989) shows a weak enrichment in LREEs and a depletion in HREEs (Fig. 12e), and the primitivemantle-normalized trace element spidergram (Sun and McDonough, 1989) illustrates an enrichment in LILEs (e.g. Cs, Rb, Ba, U and Sr), a strong depletion in HFSEs (e.g. Nb, Ta, La, Ce, Nd), and positive anomalies of Pb and Sr (Fig. 12f). The Nb/Yb, Th/Yb and Ta/Yb ratios are 7.0, 14.9 and 0.5 respectively (Table 7).
6.4. Ar-Ar dating of blueschist (sample MUD-31 and MUD-39) 40Ar-39Ar
data for phengites are summarized in Table 8 and their respective plateau ages
are shown in Figure 7. The phengites in sample MUD-31 display a flat age spectrum and a plateau age of 178.63 ± 0.93 Ma defined by 8 consecutive heating steps (> 67% of 39Ar released) with a mean standard weighted deviation (MSWD) of 1.69 (11%). Phengites from sample MUD-39 also display a very flat age spectrum and a plateau age of 175.68 ± 0.82 Ma related to 66.1% of 39Ar released (8 heating steps) with a mean standard weighted deviation (MSWD) of 1.34 (22%).
19
6.5. Granitic vein (MUD-37 sample) 6.5.1. Zircon U-Pb dating The zircons of this sample are prismatic, colorless, transparent, and have length/width ratios 0f 3:1-2:1. Cathodoluminescence images show that most zircons have clear oscillatory zones. The analyzed zircons have very variable uranium (171-3687 ppm), thorium (112-5500 ppm) and lead (8-461 ppm) contents with Th/U ratios ranging from 0.33 to 1.92 (Table 6); ratios above 0.1 indicate a magmatic origin (Hoskin and Schaltegger, 2003). Thirty-six zircons were analyzed for which the oldest concordant 206 Pb / 238 U zircon ages are 882.7±12.4 Ma and 898.6±12.8 Ma, and the youngest are 207.1±3.3 Ma and 174.6±2.7 Ma. Two main age groups are between 519.3±7.5 Ma and 481.6±7.0 Ma (55.6% of the analyzed zircons) and between 277.6±4.4 Ma and 231.8±3.8 Ma (33.3 % of all). Thus, two weighted mean
206Pb/238U
236.0±2.6 Ma. Accordingly, we interpret the concordant
zircon ages are 503.9±3.2 Ma and
206Pb/238U
zircon date of 174.6±2.7 Ma
as the time when the youngest inherited or xenocrystic zircons crystallized in the granitic vein. Therefore, this youngest 175 Ma concordant zircon age probably represents the maximum time when the dyke intruded the amphibolite rocks. On the other hand, the weighted mean
206Pb/238U
zircon ages of 503.9±3.2 Ma and 236.0±2.6 Ma, respectively linked to the concordant 519 Ma-482 Ma and 278 Ma-232 Ma zircon populations, and to the 899-883 Ma and 207 Ma zircon populations, likely represent older xenocrysts or inherited zircons, which were incorporated during the emplacement of the granitic vein (Fig. 8a).
6.5.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for the granitic vein (MUD-37) are presented in Table 7. The granitic vein sample has contents of SiO2 70.0 wt. %, Na2O 5.68 wt. %, K2O 2.00 wt. % and MgO 0.89 wt. %, and a Mg# of 33. The contents of Ni, Cr, and Cu are 13.9 ppm, 19.8 ppm
20
and 1.9 ppm respectively. The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) indicates that the vein (MUD-37) is a calc-alkaline granite (Figs. 11a and c). It has a high abundance of REEs (ΣREE = 69.1 ppm), very strong LREE/HREE ratios (=11.0) and (La/Yb)N (=11.2) ratios, a weak negative Eu anomaly (δEu =0.8), and a high Sr content (412 ppm) and high Sr/Y ratio (38) (Table 7). The chondrite-normalized REE diagram (Sun and McDonough, 1989) shows a rightdecreasing REE pattern, an enrichment in LREEs and a depletion in HREEs (Fig. 12g). A primitive mantle-normalized spider-diagram (Sun and McDonough, 1989) is characterized by an enrichment in LILEs (e.g. Cs, Rb, Ba, Th, U), a strong depletion in HFSEs (e.g. Nb, Ta, La, Ce, Nd), and positive observed anomalies of Pb and Sr (Fig. 12h).
6.6. Granodioritic vein (sample MUD-40) 6.6.1. Zircon U-Pb dating The zircons of this granodioritic are prismatic, colorless and transparent, and have length/width ratios between 3:1 and 2:1. Cathodoluminescence images of most zircons have clear oscillatory zones. The analyzed zircons display highly variable uranium (195-2790 ppm), thorium (21-2857 ppm) and lead (9-239 ppm) contents, and Th/U ratios that range from 0.14 to 1.59 (Table 6); ratios above 0.1 indicate a magmatic origin. In addition, a single metamorphic zircon has a Th/U ratio of 0.01 (Hoskin and Schaltegger, 2003). Forty-two zircons were analyzed for which the oldest concordant 207Pb / 206Pb age is 2490.7±13.1 Ma and the oldest concordant 206Pb / 238U age is 976.6±11.4 Ma. There are four time groups for the concordant
206Pb/238U
zircons between
511.7±7.4 Ma and 393.5±5.9 Ma (29 % of all analyzed zircons), 277.9±4.2 Ma and 220.4±3.3 Ma (29%), 206.9±3.2 Ma and 176.8±2.7 Ma (29 %) and 165.3±2.5 and 158.8±2.4 Ma (11.9 %), while the metamorphic zircon has a concordant 206 Pb/ 238 U zircon age of 500.6±7.3 Ma. Thus, a weighted mean 206Pb/238U zircon age of 161.4±2.5 Ma for the youngest zircon population can be interpreted
21
as the time when the youngest xenocrysts/inherited zircons were incorporated in the granodioritic magma. Therefore, this 161 Ma weighted mean zircon age closely represents the maximum time of emplacement of the granodiorite vein, whereas the older zircon populations likely represent xenocrystic/inherited zircons picked up by the granodiorite vein (Fig. 8b).
6.6.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for this granodiorite vein are given in Table 7. This sample has contents of SiO2 68.59 wt. %, Na2O 4.94. wt. %, K2O 2.76 wt. % and MgO 1.13 wt. %, and a Mg# of 38. Ni, Cr and Cu values are 8.3 ppm, 13.2 ppm and 10.8 ppm respectively. The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) indicates that this vein is a calc-alkaline granodiorite (Fig. 11a and c). Trace element analyses show enrichments of REEs (ΣREEs = 79.6 ppm), very strong LREE/HREE (=12.5) and (La/Yb)N (=18.1) ratios, but no Eu anomaly (δEu =1.0), and high values of Sr (1103 ppm) and a high Sr/Y ratio (118) (Table 7). The chondritenormalized REE diagram (Sun and McDonough, 1989) show right-plunging REE patterns, an enrichment in LREEs and a depletion in HREEs (Fig. 12g). The primitive mantle-normalized spider-diagram (Sun and McDonough, 1989) is characterized by an enrichment in LILEs (e.g. Cs, Rb, Ba,Th), a strong depletion in HFSEs (e.g. Nb, Ta, La, Ce, Nd), and positive anomalies in Pb and Sr (Fig. 12h).
6.7. Leucogranite dike (Yil-LEU-23 sample) 6.7.1. Zircon U-Pb dating The zircon SIMS results for this leucogranite dike are presented in Table 6. The zircons are prismatic, colorless and transparent, have length/width ratios between 3:1 and 2:1, and their cathodoluminescence images show that most zircons have clear oscillatory zones. The dated zircons have variable uranium (315–2364 ppm), thorium (53–2073 ppm) and lead (6-193 ppm)
22
contents, and a Th/U ratio between 0.13 and 1.50 (Table 6); ratios above 0.1 indicate a magmatic origin (Hoskin and Schaltegger, 2003). Forty-one zircons were analyzed of which the oldest concordant 206 Pb/238 U age is 505.1±7.3 Ma, whereas the youngest age is 106.9±1.7 Ma. There are four groups of concordant
206
Pb/238 U zircon ages between (1) 505.1±7.3 Ma and 449.6±6.5 Ma
(4.9% of all analyzed zircons), (2) 286.8±5.4 Ma and 260.3±3.8 Ma (7.3%), (3) 168.2±2.7 Ma and 121.4±1.9 Ma (14.6%) and (4) 114.6±1.8 Ma and 106.9±1.7 (73.2%). The youngest and predominant group of concordant zircons at 115 Ma-107 Ma provides a weighted mean 206Pb/238U zircon age of 111.9±0.7 Ma that can be interpreted as the time of intrusion, while the older populations of concordant zircon ages represent xenocrystic or inherited zircons incorporated during the leucogranitic dike intrusion (Fig. 9a).
6.7.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for this leucogranitic dike are listed in Table 7. This sample has a SiO2 content of 68.52 wt. %, a Na2O of 4.31 wt. %, a K2O of 2.76 wt. % and a MgO of 0.36 wt. %, and a Mg# of 25. The contents of Ni, Cr, and Cu are 2.1 ppm, 5.6 ppm and 10.4 ppm respectively. The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) demonstrates that this dike is a calc-alkaline leucogranite (Fig. 11a and c). It has a moderate REE abundance (ΣREE = 38.9 ppm), very strong LREE/HREE ratios (=11.8) and (La/Yb)N (=20.7) ratios, no Eu anomaly (δEu =1.1), a high concentration of Sr (269 ppm), and a high Sr/Y ratio (61) (Table 7) The chondrite-normalized REE diagram of Sun and McDonough (1989) shows a right-plunging REE pattern, an enrichment in LREEs, and a depletion in HREEs (Fig. 11i). A primitive mantlenormalized spider-diagram (Sun and McDonough, 1989) demonstrates an enrichment in LILEs (e.g. Cs, Rb, Ba, U), a strong depletion in HFSEs (e.g. Ce, La, Zr, Hf, Nb, Ta), and a positive anomaly in Pb (Fig. 11j).
23
6.8. Trachyte (sample Yil-T-2) 6.8.1. Zircon U-Pb dating The zircon SIMS data for this trachyte are listed in Table 6. The zircons are prismatic, colorless and transparent, have length/width ratios between 3:1 and 2:1, and cathodoluminescence images show that most grains have no clear oscillatory zones. The analyzed zircons have slightly variable uranium (638-1083 ppm), thorium (300-822 ppm) and lead (11-23) contents with a Th/U ratio ranging from 0.37 to 0.76 (Table 6); these Th/U ratios above 0.1 indicate a magmatic origin (Hoskin and Schaltegger, 2003). Seven zircons were analyzed for which the concordant 206 Pb/238 U zircon ages range from 106.7±1.7 Ma to103.8±8 Ma and a weighted mean age of 105.1 ±1.2 Ma is interpreted as the time of trachyte crystallization (Fig. 9b).
6.8.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for this trachyte are presented in Table 7. It contains 63.59 wt. % SiO2, 3.57 wt. % Na2O, 4.53 wt. % K2O, and 0.66 wt. % MgO, and its Mg# is 19. Cr and Cu values are 2 ppm and 10.7 ppm respectively. The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) reveals that this trachyte is shoshonitic (Fig. 10b and c). It has a strong enrichment in REEs (ΣREEs = 121.8 ppm), high LREE/HREE (=9.2) and ((La/Yb)nut=8.1) ratios, but no Eu anomaly (δEu = 0.9). The chondrite-normalized REE diagram (Sun and McDonough, 1989) shows a right-plunging REE pattern, a strong enrichment in LREEs, and a depletion in HREEs (Fig. 12i). The primitive mantle-normalized spider-diagram of Sun and McDonough (1989) shows an enrichment in LILEs (e.g. g. Cs, Rb, Ba, Th, U), a strong depletion in HFSEs (e.g. Ce, La, Zr, Hf, Ti, Nb, Ta), and a positive anomaly in Pb (Fig. 12j).
24
6.9. Monzodiorite (YIL-G-15 sample) 6.9.1. Zircon U-Pb dating The analyzed zircon SIMS data for this monzodiorite are presented in Table 6. The dated zircons are prismatic, colorless and transparent. Their length/width ratios are between 1:1 and 2:1. Cathodoluminescence imaging illustrates clear oscillatory zones in most zircon grains. The analyzed zircons have uranium (210-1690 ppm) and thorium (29-1494 ppm) contents, clearly higher than their lead (12-243 ppm) content. 17 on 18 analyzed zircons have Th/U ratios ranging from 0.12 to 1.12, which indicate a magmatic origin. In addition, one metamorphic zircon has a Th/U ratio of 0.05 (Hoskin and Schaltegger, 2003). 18 zircons were analyzed for which the oldest concordant 206 Pb/207 Pb zircon age is 1441.8±13.5 Ma, while the youngest concordant 206 Pb / 238 U zircon age is 101.2±1.6 Ma. The oldest concordant
206
Pb/207 Pb and
206
Pb/238 U zircon ages
define a first group between (1) 1441.8±13.5 Ma and 822.7±11.8 Ma (22.2% of analyzed zircons). Two younger groups of concordant
206
Pb/238 U zircon ages are between (2) 645.1± 9.5 and
433.5±6.5 Ma (27.8 % of analyzed zircons) and (3) 313.9±4.6 and 178.3±2.8 Ma (44.4 % of analyzed zircons). Within this last age group, the metamorphic zircon has a concordant 206 Pb/ 238 U zircon age of 298.2±8.9 Ma (Fig. 9c). We interpret the youngest concordant
206Pb/238U
zircon
age of 101.2±1.6 Ma as the time when the youngest inherited or xenocrystic zircons were incorporated into the monzodioritic magma. Accordingly, this monzodioritic rock was likely emplaced at or after 101.2±1.6 Ma. It can therefore be argued that this 101 Ma zircon likely represents the maximum age of intrusion of the monzodiorite, and the older populations of concordant zircons are xenocrystic or inherited grains.
25
6.9.2. Whole-rock major and trace element geochemistry Major, trace and rare earth element data for this monzodiorite are given in Table 7. Its contents of SiO2 are 50.75 wt. %, Na2O 3.59 wt.%, K2O 1.75 wt %, and MgO 7.63 wt %, and its Mg# is 54. The measured Ni, Cr, and Cu values are 198.0 ppm, 353.0 ppm and 24.4 ppm respectively. The K2O versus SiO2 diagram (Pecerrillo and Taylor, 1976) reveals that the monzodiorite belongs to the high-K calc-alkaline series (Fig. 11a and c). It has a strong enrichment in total REEs (ΣREE = 141.2 ppm), high LREEs/HREEs (=7.7) and (La/Yb)N (=7.6) ratios, and no negative Eu anomaly (δEu = 0.9). The chrondrite-normalized REE diagram (Sun and McDonough, 1989) shows a right-plunging (re-phrase) REE pattern, a weak enrichment in LREEs, and a depletion in HREEs (Fig. 12i).
The primitive mantle-normalized spider diagram (Sun and
McDonough, 1989) shows an enrichment in LILEs (e.g. Cs, Rb, Ba, Th, U), a strong depletion in HFSEs (e.g. Nb, Ta, La, Ce, Zr, Hf,), and a positive anomaly in Pb (Fig. 12j).
7. Discussion 7.1. Magma genesis 7.1.1 The adakitic leucogranite The leucogranite (Yil-LEU-14) contains an enrichment in lithophile elements (LILEs) and LREEs and a depletion in high field strength elements (HFSEs) (Fig. 12c and d). These trace elements highlight the fact that this leucogranite was emplaced in an active continental margin setting (Gill, 1981; Grove et al., 2003). The observed positive anomaly in Pb indicates upper crustal contamination (Zhu et al., 2017d). The leucogranite has a weak REE abundance, a relatively flat LILEs pattern, low LREEs/HREEs and (La/Yb)N ratios. These trace element values are explicable by the presence of minor garnet in a HP mafic granulite source (Martin, 1999; Yu et al., 2019). The lack of important plagioclase fractionation is highlighted by the heavy positive Eu and Sr
26
anomalies. A residual amphibole in a HP mafic granulite source is also inferred by the heavy positive Zr and Hf and negative Nb and Ta anomalies (Martin, 1999; Hastie et al., 2010). The low Th/U ratios of
< 0.01 measured inside the zircons indicate a metamorphic origin for the
leucogranite. The high concentration of Sr (324 ppm) coupled with high Sr/Y ratios (=308) further reveal an adakitic source (Defant and Drummond, 1990; Martin, 1999; Fig. 14). The high concentrations in K2O (4.07 %) and SiO2 (78.5%) and low concentrations in MgO (0.11%), Ni (2.1) and Cu (2.60 ppm) coupled with low Mg# (28) suggest an absence of interaction between this high-silica adakitic leucogranite and a mantle wedge. Thus, the geochemical features exclude a generation by melting of an oceanic slab or delaminated continental crust, and more likely suggest a derivation from melting of a thickened lower crust (Moyen, 2009; Wang et al., 2005; Yu et al., 2019).
7.1.2. The gabbro The 211 Ma gabbro (Yil-GAB-16 sample) from the eastern edge of the Zhangguancai Range magmatic arc has an enrichment in lithophile elements (LILEs) and LREEs and a depletion in high field strength elements (HFSEs) (Fig 12e and f). These trace elements patterns indicate that this gabbro was emplaced in an active continental margin setting (Gill, 1981; Grove et al., 2003). The Nb/Yb vs Th/Yb and Nb/Yb vs Ta/Yb classification diagrams (Dilek and Furnes, 2014; Pearce, 2014) also support a continental arc-setting for this gabbro (Fig. 13). The observed positive anomaly in Pb argues for upper crustal contamination (Zhu et al., 2017d). The strong positive Sr anomaly indicates an absence of plagioclase fractionation, whereas the slightly fractionated REE pattern and strong Y depletion imply a garnet-bearing source (Martin et al., 1999; Yu et al., 2019; Fig 12e). The strong negative anomalies in Nb and Ta may also indicate the presence of amphibole or rutile in the residue (Hastie et al., 2010). Furthermore, the high concentrations of Sr (835 ppm)
27
and the high Sr/Y ratio (=286) also suggest that this gabbro was derived from an adakitic source (Defant and Drummond, 1990; Martin, 1999; Fig. 14). The strong concentrations in MgO (6.55 wt. %), Ni (54.6 ppm) and Cr (265 ppm) suggest interaction of the original melt with ultramafic rocks of a mantle wedge (Martin, 1999; Moyen, 2009). These geochemical patterns suggest that the gabbro was likely sourced from an adakitic primary melt developed during slab melting. During its ascent, the primary melt interacted with a mantle wedge and was then emplaced into a continental arc (Moyen, 2009).
7.1.3. The adakitic granitic/granodiorite veins The granodiorite (MUD-37) and monzogranitic vein (MUD-40) show enrichments in lithophile elements (LILEs) and LREEs, a depletion in high field strength elements (HFSEs), and a positive anomaly in Pb (Fig. 12g and h). These trace element values provide evidence that these rocks formed in an active continental margin with some upper crustal contamination (Gill, 1981; Grove et al., 2003; Zhu et al., 2017d). Furthermore, the high concentration of Sr (412 ppm-1103 ppm), high Sr/Y (38-118) and La(N)/Yb(N) (=11.1-18.1) ratios reveal that these granitic and granodiorite veins were generated in a thickened adakite magma source (Defant and Drummond, 1990; Martin, 1999; Fig. 14), and emplaced at a maximum age of 175-161 Ma. The highconcentrations in SiO2 (68.6-70.0%) and K2O (2.00-2.78 %) suggest that these granitic and granodiorite veins were sourced from high-silica adakitic fluids (Martin et al., 2005). The high Sr/Y and steep rare earth element (REE) patterns indicate equilibrium with a garnet/clinopyroxenebearing eclogitic residue after melting of subducted oceanic crust (Defant and Drummond, 1990; Stern et al., 2002; Yu et al., 2019). The slight positive Sr and negative Nb-Ta anomalies respectively reveal the absence of plagioclase and the presence of amphibole or rutile in the melt residue (Martin, 1999; Hastie et al., 2010). On the other hand, the relatively low MgO (0.89-1.13
28
wt.%), Ni (8.30-13.90 ppm) and Cr (13.20-19.80 ppm) contents of these granodiorite/granitic rocks highlight the absence of interaction between their melt and ultramafic rocks of a mantle wedge or subduction channel (Martin, 1999; Moyen, 2009; Blanco-Quintero et al., 2011). Thus, these granitic/granodiorite veins were likely sourced from partial melting of a slab (Moyen, 2009).
7.1.4. Magmatic rocks at 112-101 Ma The 112-101 Ma magmatic and volcanic rocks (YIL-LEU-23, YIL-T-2 and Yil-G-15) exhibit an enrichment in lithophile elements (LILEs) and LREEs and a depletion in high field strength elements (HFSEs) (Fig. 12i and j). These trace elements features are evidence that the rocks formed in an active continental margin (Gill, 1981; Grove et al., 2003). The positive anomaly in Pb further indicates an upper crustal contamination (Zhu et al., 2017d). However, the 112 Ma leucogranitic dike (Yil-LEU-23) has a lower REE abundance, a relatively steep LILE patter, and strong LREEs/HREEs and (La/Yb)N ratios compared with the 105 Ma trachyte (Yil-T-2) and 101 Ma dated monzodiorite (Yil-G-15 sample). These differences in trace elements might be explained by the presence of garnet in the source of the 112 Ma leucogranitic dike (Martin, 1999; Yu et al., 2019). The presence of amphibole or rutile in the melt residue might also be indicated by the negative Nb-Ta anomalies (Blanco-Quintero et al., 2011; Hastie et al.,2010). Moreover, the high concentration of Sr (269 ppm), and high Sr/Y (= 61) and La(N)/Yb(N) (=20.7) ratios indicate that this leucogranite dike was sourced from an adakite-type magma (Defant and Drummond, 1990; Martin, 1999; Fig. 14). The high-concentrations in K2O (2.8 %) and SiO2 (68.5 %) and low concentrations in MgO (0.4 %), Ni (2.1 ppm), Cr (5.6 ppm) and Cu (10.4 ppm) coupled with a low Mg# (25) highlight the absence of interaction of the high-silica adakitic rocks with a mantle wedge (Blanco-Quintero et al., 2011; Martin, 1999; Moyen, 2009;). Thus, the geochemical patterns most
29
likely suggest generation by melting of a thickened lower crust instead of a subducted oceanic crust (Moyen, 2009; Wang et al., 2005, Yu et al., 2019).
7.2. New insights for the formation of the HP Heilongjiang Complex 7.2.1. Metabasites The blueschist YIL-BLUE-19 had the protolith composition of an alkali basalt (Fig. 10b). The chondrite-normalized diagram (Sun and McDonough, 1989; Fig. 12a) indicates that it has a REE pattern similar to that of OIBs including a right-plunging REE pattern, a strong enrichment in LREEs, a depletion in HREEs, a very strong REE abundance (ΣREEs = 318 ppm) and high LREEs/HREEs (5.6) and (La/Yb)N (26.7) ratios. The primitive mantle-normalized trace element variation diagram (Sun and McDonough, 1989; Fig. 12b) confirms the trace element pattern compatible with an OIB geo-setting with an enrichment in LILEs (e.g. Rb, Ba, Th, and Sr) and HFSEs (e.g. Nb, Ta, La, Nd). The Nb/Yb vs. Th/Yb and Ta/Yb vs Th/Yb discrimination diagrams (Dilek and Furnes, 2014; Pearce, 2014) supply further evidence of an OIB-type setting for the protolith of this blueschist (Fig. 13). Moreover, an OIB-related formation is in accordance with the geochemical analyses of neighboring blueschists in the Yilan area (Ge et al., 2016; Zhou et al., 2009; Zhu et al., 2015; 2017a). The lack of a positive anomaly in Pb indicates the absence of crustal contamination during the ascent of magma. The weak Mg# value (33) indicates that the magma source underwent clinopyroxene and/or olivine fractionation, while the high LREEs/HREEs (5.6) and (La/Yb)N (26.7) ratios highlight the presence of garnet in the source (Ge et al., 2016; Zhu et al., 2015). Furthermore, the lack of a Eu anomaly (δEu = 1.11) indicates that the plagioclase was not a major fractionating phase in the source and in the evolving magma. Thus, an asthenospheric mantle with no or little crustal contamination is consistent with the magma source of the blueschist. Therefore, we propose that the alkali basalt formed in an oceanic island.
30
The OIB-type trace element pattern suggests that the protolith of the blueschist (YILBLUE-19) was emplaced in an oceanic island setting and derived from an asthenospheric source. The youngest 356 Ma crystallization age of the inherited/xenocrystic zircons indicates that the metabasaltic protolith was emplaced after 356 Ma. With regards to this new age constraint, the compilation of previously published protolith ages of blueschists and amphibolites shows a range from 356 Ma to 142 Ma (Table 4; Fig. 15), with two main peaks at 257 Ma and 142 Ma. Two divergent hypotheses were proposed to explain the setting of the protoliths of these metabasites. One group suggested that the oldest original rocks formed in a Permian continental rift between the Jiamusi and Songliao Blocks. This geodynamical model is notably supported by the presence of old inherited zircons in 307-281 Ma OIB blueschists and amphibolites in the Central Asian Orogenic Belt (CAOB) (Zhou et al., 2009, 2010; Zhu et al., 2015, 2017a; Table 4). A recent study considered that the oldest basaltic rocks in the HP Heilongjiang Complex formed in a back-arc basin, which developed at the eastern edge of the CAOB between 290 Ma and 260 Ma (W. Han et al., 2019). However, others have proposed that inherited zircon grains can result from wind or river transport and considered that a wide ocean was linked to the Paleo-Pacific realm rather than a narrow oceanic basin located at the eastern edge of the CAOB between the Jiamusi and Songliao Blocks (Ge et al., 2016, 2017, 2018). From these points of view, the absence of HFSE depletion in our OIB meta-basalt as well as in the older blueschists (Ge et al., 2016; Zhou et al., 2009, 2010, 2014; Zhu et al., 2015a, 2017a) argues against the idea that the original basalts were emplaced in a back-arc basin where HFSE depletion is a major trace element feature (Pearce and Stern, 2006). Thus, the geochemical analyses coupled with our new zircon ages highlight the fact that the original basalts were likely emplaced in a wide oceanic basin (named the “Mudanjiang Ocean”) 31
from an asthenospheric source instead of a narrow back-arc basin/seaway, as recently proposed by Ge et al. (2016, 2017, 2018). These authors assumed that the large “Mudanjiang” ocean already existed since ca. 288 Ma at least in the early Permian. By integrating previously published 308 Ma281 Ma protolith ages of metabasites with our new 356 Ma, considered to be the maximum age of emplacement of the OIB basalt (Table 4; Fig. 15), we emphasize that these oldest metabasites in the HP Heilongjiang Complex were initially emplaced in a wide oceanic basin that was already open in Carboniferous-early Permian time between the eastern edge of the CAOB and the Jiamusi Block. Thus, these Carboniferous protolith ages reveal that the wide “Mudanjiang” ocean already existed since the Carboniferous time, much older than previously considered. Furthermore, a Carboniferous oceanic basin allows us to explain the differences of the Permian sedimentary sequences as well as the different crustal nature between the western Jiamusi Block and the easternmost Songliao Block, which altogether argue against the Permian rift model for the Jiamusi– Songliao blocks (Yang et al., 2017, 2019). Recent studies considered that the “Mudanjiang” ocean was still open at the end-Jurassic to early Cretaceous as supported by young 161 Ma-142 Ma protolith zircon ages of blueschists and greenschists in the HP Heilongjiang Complex (Zhu et al., 2015, 2017a; Table 4). Thus, it appears that the upper and lower limits of existence of the “Mudanjiang Ocean” span from 356 Ma to 142 Ma, which indicate a long-lived ocean between the Songliao and Jiamusi Blocks.
7.2.2. Igneous rocks A compilation of published protolith zircon ages indicates that the granitic and volcanic rocks located inside the HP Heilongjiang Complex exhibit two main zircon populations respectively around 262 Ma and 211 Ma with minor older components (Fig. 15; Table 4). The 245 Ma maximum protolith age of our dated Yil-LEU-14 leucogranite sample is in accordance with the
32
262 Ma prominent peak of protolith zircon ages for the granitic and volcanic rocks in the HP Heilongjiang Complex (Fig. 15). The Permian granitoids and early Paleozoic rocks of the Mashan Complex in the Jiamusi Block were until recently considered to be the main source of the protoliths of these early Paleozoic and Permo-Triassic magmatic rocks, and later incorporated into the HP Heilongjiang Complex (Zhou et al., 2010). Nevertheless, recent studies also suggest a provenance from the Zhangguancai Range magmatic arc in addition to the Jiamusi Block (Dong et al., 2017a, 2017b, 2018a, 2018b, 2019). Our review of zircon ages of the whole orogenic system (Table 1, 2, 4 and 5; Fig. 15) shows that granitic and volcanic rocks inside the HP Heilongjiang Complex apparently had a 262 Ma peak protolith zircon age similar to the peak zircon ages at 258 Ma in the Jiamusi Block. However, no late Triassic magmatic activity is recorded in the Jiamusi Block, whereas a 211 Ma peak protolith zircon age is clearly distinguished for the granitic and volcanic rocks incorporated into the HP Heilongjiang complex. On the other hand, a late Triassic 211 Ma zircon age peak in magmatic activity is also observed in the Zhangguancai Range magmatic arc. In addition, magmatic activity with zircon age peaks at 241 Ma, 261 Ma and 271 Ma was additionally recorded in the Zhangguancai Range magmatic arc, and well correlates with the 262 Ma peak of protolith zircon ages of granitic rocks inside the HP Heilongjiang Complex. Furthermore, the older 492 Ma and 436 peaks of protolith zircon ages of the granitic and volcanic rocks in the HP Heilongjiang Complex may be correlated with the zircon age peaks at 491 Ma, 451 Ma and 425 Ma in the Zhangguancai Range magmatic arc (Table 2; Fig. 15). Accordingly, we assume that the granitic and volcanic rocks inside the HP Heilongjiang Complex were likely sourced from the neighboring Zhangguancai Range magmatic arc (i.e in the eastern Songliao Block) rather than the Jiamusi Block. 33
7.2.3. Metasediments Concerning the zircon age populations in metasediments of the HP Heilongjiang Complex, three main peaks were recorded at 494 Ma, 255 Ma, and 228-200 Ma with minor components, which were continuous from 600 Ma to 160 Ma (see Table 4 and references therein). By comparing with the main 505 Ma-490 Ma, 389 Ma and 258 Ma-290 Ma zircon age populations of the Jiamusi Block as well as the 491 Ma-451 Ma, 317 Ma, 271 Ma-241 Ma and 211 Ma-200 Ma zircon age populations of the Zhangguancai Range magmatic arc, we infer that the zircon age populations in the metasediments confidently overlap those of the Jiamusi Block as well as the Zhangguancai Range magmatic arc (Fig. 15). The newly dated xenocrysts and inherited zircons in the 175-161 Ma granitic and granodiorites veins (MUD-37 and MUD-40 samples) and in the 112-101 Ma igneous rocks (YILLEU-23, Yil-T-2 and YIL-G-15 samples) in the HP Heilongjiang Complex, exhibit zircon age peaks at 507 Ma, 260-238 Ma and 205 Ma with some minor populations between these age spans. These new dates are also consistent with the main 505 Ma-490 Ma, 389 Ma and 258 Ma-290 Ma zircon age populations of the Jiamusi Block as well as the 491-451 Ma, 317 Ma, 271-241 Ma and 211-200 Ma zircon populations of the Zhangguancai Range magmatic arc (Fig. 15). In addition, a younger 185 Ma zircon age peak recorded in the Zhangguancai Range magmatic arc is consistent with the 185 Ma and 167 Ma zircon age peaks of xenocrysts and inherited zircons in the 175-161 Ma granitic and granodiorites veins (MUD-37 and MUD-40 samples) and the 112-101 Ma igneous rocks (YIL-LEU-23, Yil-T-2 and YIL-G-15 samples) (Fig. 15). Moreover, there is a significant 200-167 Ma zircon age population in the histogram of detrital zircon ages of metasedimentary rocks in the HP Heilongjiang Complex (Table 4 and references
34
therein; Fig. 15). This young zircon age population manifestly matches the 185 Ma zircon age peak described in the Zhangguancai Range magmatic arc. With regard to all the presented data above, eroded sediments either sourced from magmatic rocks of the Zhangguancai Range magmatic arc or the Jiamusi Block were both deposited during formation of the HP Heilongiang Complex, as suggested by Dong et al. (2018a).
7.3. Evidence for subduction in the eastern Songliao Block during the Late Triassic Our new weighted mean 206Pb/238U SIMS zircon age of 211±1 Ma on deformed gabbro near Yongshuncun village provides useful information about the subduction process, which occurred on the eastern margin of the Songliao Block in the Zhangguancai Range magmatic arc. Some studies recently considered that the geochemistry of these late Triassic igneous rocks suggests an extensional tectonic setting related to the closure of the Paleo-Asian Ocean (Guo et al., 2016; Xu et al., 2009, 2013). In contrast, these late Triassic igneous rocks have also been linked to an active margin related to the subduction of the Paleo-Pacific Ocean (Ge et al., 2018, Zhao et al., 2018; Zhu et al., 2017d). Moreover, these authors have opined that the Triassic to early Jurassic protolith ages of metabasalts with OIB and E-MORB affinities and metasedimentary rocks provide strong evidence that an ocean still existed, and was subducted below the eastern edge of the Songliao Block (Table 4). The continental adakitic arc-type geochemical character (see part 7.1.3) of our sampled gabbro clearly indicates that an active continental margin was still in existence in the eastern Songliao Block in the Zhangguancai Range magmatic arc at the end of Triassic time. However, the absence of coeval late Triassic igneous rock located on the western edge of the Jiamusi Block
35
challenges the double-sided subduction model to explain the tectonic evolution of the Mudanjiang Ocean, as proposed by Dong et al. (2017a, 2017b, 2018a, 2018b).
7.4. HP metamorphic event and implications for the subduction process The age of the HP metamorphism of the HP Heilongjiang Complex remains controversial with proposed times in the Paleozoic (Wang et al., 2012; Zhang et al., 2018), late Triassic to early Jurassic, (Wu et al., 2007; Zhou et al., 2009; 2010; 2013; Zhou and Li, 2017) or late Triassic to early Cretaceous (Ge et al., 2016, 2017, 2018; Zhu et al., 2015, 2017a, 2017b, 2017c, 2017d). Our new geochronological Ar-Ar dates on blueschists in the Mudanjiang area give Ar-Ar phengite plateau ages at 178.6 ± 0.9 Ma and 175.7 ± 0.8 Ma. These new robust 179 Ma-176 Ma Ar-Ar ages provide evidence that most radiometric ages on metamorphic minerals from the HP Heilongjiang Complex are between 198 Ma and 164 Ma (Table 5; Fig. 15). On the other hand, the 175-161 Ma maximum ages for the emplacement of the granodiorite and granitic veins that intruded the HP Heilongjiang Complex can constrain the lower limit of the HP metamorphic event in the Mudanjiang area. Notably, the 161 Ma maximum age of the intruded granodiorite vein can be regarded as the lower limit of the HP metamorphism in the Mudanjiang area. From this point of view, the lower limit of the HP metamorphism of the HP Heilongjiang Complex at the Mudanjiang area may likely be at 164 Ma-161 Ma. The oldest radiometric Ar-Ar metamorphic ages in the Mudanjiang area are between 198 Ma and 195 Ma on Ca-amphiboles and biotites (Ge et al., 2017; Zhou et al., 2013; Table 5), 197190 Ma in the Luobei area by LA-ICP-MS dating on zircons and Rb-Sr dating on biotites (Han et al., 2019; Wu et al., 2007; Table 4 and 190 Ma in the Yilan area by Ar-Ar dating on phengite (Li et al., 2011; Table 5). Accordingly, the upper limit of the HP metamorphism, which initially
36
affected the HP Heilongjiang Complex in the Luobei and Mudanjiang area, is ca. 198 Ma-195 Ma, while the HP metamorphism is slightly later in the Yilan area at ca.190 Ma (Table 5). Furthermore, correlation between the metamorphic grade and the radiometric ages shows that the oldest 198-190 Ma ages are recorded in gneisses and amphibolites, while blueschists and neighboring micaschists yield 185 Ma to 145 Ma radiometric ages (Table 5). Based on these data, it can be assumed that the metamorphic event in the HP Heilongjiang complex started in a relatively hot subduction environment, which cooled through a time span of 53-13 Ma. As demonstrated in recent studies (Agard et al., 2016), it can be proposed that fluids released throughout the subduction channel might play a significant role in this transition of the metamorphic grade in the HP Heilongjiang Complex. In the eastern Yilan area new 161-159 Ar-Ar ages on glaucophanes (Zhu et al., 2017b; Table 5) and 146-145 Ma Ar-Ar on phengites (Li et al., 2009; Table 5) from metamorphic rocks might be considered as the lower limit of the HP metamorphic event, which affected the whole HP Heilongjiang Complex (Ge et al., 2016; Zhu et al., 2017b). Thus, these youngest late Jurassic radiometric ages indicate that the HP metamorphic event related to a subduction process was still in operation in the HP Heilongjiang area in the Jurassic (Zhu et al., 2017b).
7.5. Evidence for ridge subduction in the Early Jurassic A major tectonic control in the formation of accretionary orogens is ridge–trench interaction (Windley et al. 2007). This particular process can notably be recognized in ancient accretionary orogens by the presence of adakite dykes, which intrude a fore-arc accretionary complex near the trench (Windley and Xiao, 2018). In the Mudanjiang area granitic adakite and granodiorites veins that intruded the HP Heilongjiang Complex originated by partial melting of dehydrated subducted oceanic crust (see
37
part 7.1.4). Thus, these granitic/granodiorite veins in the HP Heilongjiang complex can be regarded as adakite fluids sourced from ridge-generated magmas, which later rose through the accretionary complex. Complementary to these specific geochemical patterns presented above, the E-MORBsourced metabasites together with mudstones, tuffs, and meta-chert protoliths of the metasedimentary rocks (Cao et al., 1992; Wu et al., 2007, Zhou et al., 2009) supply further major evidence of a subducted mid-oceanic ridge. Former ocean plate stratigraphy (mid-oceanic ridge basalt, pelagic chert/limestone, hemipelagic mudstone and trench clastic sediments (Kusky et al., 2013; Wakita et al., 2013) can be inferred from the different lithologies in the HP Heilongjiang Complex. We therefore assume that these accreted and mixed materials were initially generated near a mid-oceanic ridge, which was subducted into the mantle when these ocean floor sediments were added to the accretionary complex (Windley and Xiao, 2018). Thence, the 175-161 Ma maximum age of the intruded adakitic fluids in the HP Heilongjiang Complex is useful to constrain the time of entry of the mid-oceanic ridge into the subduction zone. Taking into account the fact that a hot subducting lithospheric slab younger than 25-30 Myr was required to enhance the production of the adakitic fluids by slab melting (Defant and Drummond, 1990; Martin, 1999), we can infer that subduction of the mid-oceanic ridge started after 205-200 Ma near the Triassic-Jurassic transition.
7.6. ENE/NE-strike-slip faulting The whole accretionary system (accretionary complex, basement and magmatic arc) was dissected by the ENE-trending Dunhua-Mishan and NE-trending Yilan-Yitong transcurrent faults, which are the northerly extension of the Tan-Lu Fault. A major effect of these regional strike-slip movements was the northeasterly shift of the Khanka Lake granitoids, which were displaced by
38
about 150-200 km from the southern edge of the Zhangguangcai Range Magmatic arc, alongside the ENE-oriented Dunhua-Mishan transcurrent fault (K. Liu et al., 2018). A recent study by Zhao et al. (2019) endorses sinistral northward displacement of the Khanka-Jiamusi-Bureya Block to its present position after Mesozoic subduction of the paleo-Pacific Ocean. Until recently, these regional NE/ENE-oriented wrench faults were considered to reflect the late Permian to late Triassic-early Jurassic NE-directed extrusion of NE China during the closure of the Paleo-Asian Ocean (Şengör and Natal’in, 1996; Şengör et al., 2014; Xiao et al., 2015). However, recent structural data coupled with U-Pb dating of syn and post-tectonic magmatic intrusions have recently demonstrated that these NE-ENE regional strike-slip faults were also active in Jurassic and Cretaceous times (C. Liu et al., 2018). In detail, these new 223-161 Ma UPb zircon dates of deformed granites and dykes constrain the age of the first phase of sinistral, transpressional, ductile movements from the late Triassic to late Jurassic (Table 2). In addition, the Dunhua-Mishan transcurrent fault was still active through the early Cretaceous until 129 Ma. (C. Liu et al., 2018; K. Liu et al., 2018). This first late Jurassic - early Cretaceous transpressional phase was either linked to the final closure of the Mongol-Okhotsk Ocean or to the NNW-directed subduction of the Izanagi Plate, which moved at 30 cm/year through this period (Maruyama et al., 1997). Previous structural and geochronological analyses of the HP Heilongjiang Complex and Dunhua-Mishan transcurrent fault are tentatively integrated with this study in order to present a suitable time-frame for the interaction between the HP Heilongjiang Complex and these ENE/NEtrending transcurrent faults. Recent structural and U-Pb dating of ductily deformed magmatic rocks located in the transpressional ENE-trending Dunhua-Mishan transcurrent fault demonstrate there was activity from 223 Ma to 161 Ma (C. Liu et al., 2018; Table 2). These authors also suggested that this 39
deformation phase continued until 129 Ma in the middle Cretaceous. On the other hand, the 198145 Ma HP metamorphic event that affected the HP Heilongjiang Complex was associated with the development of a NS-striking primary foliation during the exhumation of the HP Heilongjiang Complex, which shifted locally towards EW at ~160 Ma (Aouizerat et al., 2018). In addition, the the fact that the new NE-ENE foliation affected the inner HP Heilongjiang Complex along the ENE-trending Dunhua-Mishan and NE-trending Yilan-Yitong transcurrent faults (see Part 3.1.3) highlights the N to ENE/E-trending shift of the foliation. Accordingly, the original N-striking foliation has been largely overprinted by these regional NE-ENE transcurrent faults. Concerning the time-frame, the 223-161 Ma zircon age peaks associated with the ENEtrending Dunhua-Mishan transcurrent fault encroaches the 198 Ma upper age limit of HP metamorphism, while the youngest 129 Ma time of the Dunhua-Mishan transcurrent fault activity overlaps the 145 Ma lower limit of HP metamorphism (Table 2 and 5; Fig. 15). Consequently, the development of the regional network of sinistral ENE/NE-trending transcurrent faults must be considered to be coeval with the subduction process, which triggered the HP metamorphism of the high-pressure Heilongjiang complex.
7.7. 112-101 Ma post-accretionary event At the beginning of the late Cretaceous, the regional NE/ENE-trending strike-slip faults were reworked as a consequence of north-directed paleo-Pacific subduction. This second brittle transpressional phase was between 102 Ma and 96 Ma and it affected older magmatic rocks emplaced between 115 and 102 Ma (C. Liu et al., 2018). Cretaceous accretionary complexes developed along the eastern margin of the CAOB because of the trench retreat and slab-roll back of the Paleo-Pacific Ocean (Ma et al., 2017; Zhou et al., 2014). As a response, widespread, late early Cretaceous, intra-continental volcanism started
40
in the back-arc area, and the bordering Zhangguancai Range magmatic arc, Jiamusi Block and HP Heilongjiang Complex were subject to igneous intrusions from 124 Ma to 100 Ma, as dated by SHRIMP and LA-ICP-MS on zircons (K. Liu et al., 2019; M.D. Sun et al., 2018; Wu et al., 2011; Xu et al., 2013; Tables 1 and 2). The 112-101 Ma granitoids and volcanic rocks in the HP Heilongjiang Complex constrain the upper limit of the accretionary process that formed the HP Heilongjiang Complex (Fig. 15). These post-accretionary igneous rocks can be linked with the regional early Cretaceous back-arc magmatism in NE China, which marks a transition from the earlier continental arc and its eastward migration at ca. 124-100 Ma (K. Liu et al., 2019; M.D. Sun et al., 2018). As discussed above (see part 7.1.5), a metasomatized lithospheric mantle with local adakitic fluids can explain the geochemical patterns associated with the volcanic arc.
7.8. Jurassic tectonic erosion in NE China Even if the timing and circumstance of formation of the HP Heilongjiang Complex remain contentious (Dong et al., 2017, 2018; Ge et al., 2016, 2017, 2018; Han et al., 2019; Zhou et al., 2009, 2010; Zhou and Li, 2017; Zhu et al., 2015, 2017a, b, c, d), most previous studies considered that NE China was affected by unidirectional oceanward extension during west-directed PaleoPacific subduction in the Mesozoic (Zhou et al., 2014; Zhou and Li, 2017). It is commonly accepted that Pacific-type-orogeny comprises the following crustal features from ocean to continent: (1) an accretionary complex including a HP metamorphic belt, (2) a forearc basin, (3) a major magmatic arc (Maruyama, 1997). However, such a crustal architecture is not present along the HP Heilongjiang Complex, which is directly juxtaposed against the eastern edge of the Zhangguancai Range magmatic arc, but without a forearc basin and accretionary wedge.
41
As a result of recent studies, it is now envisioned that the HP Heilongjiang Complex is a subduction mélange, which mainly developed during the Jurassic epoch (Wu et al., 2007; Zhou et al., 2009). As presented above (see part 7.2), the youngest protolith ages of meta-basalts are dated as 162-142 Ma, and the 211 Ma granitic rocks, which originated in the neighboring Zhangguancai Range magmatic arc (i.e in the eastern Songliao Block), may be considered as the youngest granitic rocks incorporated in the subduction mélange. Moreover, most of the youngest age peaks are based on 200 Ma to 167 Ma detrital zircons, which are interpreted as the youngest ages of deposition of sediments during formation of the HP Heilongjiang Complex (Dong et al., 2018a; Ge et al., 2016; Li et al., 2011; Zhou et al., 2010; Zhu et al., 2017c; Table 4). Thus, we can conclude that the subduction mélange developed in a subduction channel from 211 Ma to 142 Ma. Simultaneously, the HP Heilongjiang Complex underwent HP metamorphism and was exhumed up the subduction channel between 198 Ma and 161-145 Ma, as supported by our new 179-176 Ma Ar-Ar phengite ages and the 175-161 Ma maximum ages for the emplacement of the adakitic granodiorite and granitic veins in the HP Heilongjiang Complex. In the same period a westward migration of a magmatic front by 60 -80 kilometers after 195 Ma is indicated by a spatial analysis of earlier Permian to Jurassic U-Pb zircon ages of granitoids and volcanic rocks that formed the Zhangguancai Range magmatic arc (Table 2; Fig. 16). Specifically, most youngest zircons ages (195 Ma to 166 Ma) are located in the east Zhangguancai Range magmatic arc, whereas the older zircons ages (266 Ma to 195 Ma) predominantly occur in the east Zhangguancai Range magmatic arc near the HP Heilongjiang Complex, as pointed out by Ge et al. (2017). In addition, we can infer that a mid-oceanic ridge started to subduct beneath the Zhangguancai Range magmatic arc at about 205 – 200 Ma (see Part 7.5). The above points provide information on: (1) the missing forearc basin, basement and accretionary wedge, (2) the coeval emplacement and exhumation of the subduction mélange during 42
HP metamorphism, (3) the presence of granitic blocks, sourced from a neighboring magmatic arc, and (4) the continent-ward migration of a magmatic front, which together point to an episode of subduction/tectonic erosion (Clift et al., 2005; Isozaki et al., 2010, 2011; Key (NB Kay in the references) et al., 2005; Maruyama et al., 2011; Suzuki et al., 2010). In a similar manner to the Japanese Islands, this episode of subduction/tectonic erosion may have been triggered at about195 Ma as a result of the entry into the subduction zone of a mid-oceanic ridge beneath the Songliao Block at 205 – 200 Ma. As a consequence, the eastern edge of the Songliao Block was eroded from the former trench to form the subduction mélange, which was juxtaposed with an older Triassic magmatic arc located along the Zhangguancai Range magmatic arc, whilst the arc front coevally migrated towards the Asian continent. Moreover, we note that the subduction erosion occurred in the period 60-50 Myr, which was a long time-span for a single tectonic erosional event. During the Mesozoic tectonic evolution of the Japanese Islands, the Sangabawa and Shimanto HP metamorphic belts were respectively exhumed from 140 Ma to 110 Ma and from 80 Ma to 60 Ma by two distinct tectonic erosion events (Aoki et al., 2012; Isozaki et al., 2010; Maruyama et al., 2011). By comparing the tectonic evolution of the HP Heilongjiang Complex with the tectonic evolution of the Japenese islands, we suggest there were two distinct episodes of tectonic erosion during the formation and exhumation of the HP Heilongjiang Complex. Nevertheless, further studies are required to decide if multiple rather single HP metamorphic belts were exhumed during the formation and evolution of the HP Heilongjiang Complex.
7.9. Accretionary processes in NE China Here we shall integrate our new data and ideas with all previous relevant research in order to propose a new tectonic evolutionary model for the discontinuous accretionary processes in NE
43
China from the Carboniferous to Cretaceous, which may be similar to the recent syntheses and tectonic evolution of the Japanese Islands (Isozaki et al., 2010, 2011; Maruyama et al., 2011; Fig. 17). The previously published 308-281 Ma protolith ages of metabasites and our new 356 Ma maximum age for the OIB basalt (see. Part 7.2.1) support the concept that a wide oceanic basin named “the Mudanjiang ocean” (Ge et al., 2016, 2017, 2018) located at the eastern edge of the CAOB, was already in existence in Carboniferous time between the Songliao and Jiamusi Blocks. At about 305 Ma the eastern boundary of the Jiamusi Block changed from a passive to active margin with the emplacement of voluminous calc-alkaline magmatism around 310-305 Ma when there was a 275-245 Ma westward younging of the magmatic arc (G.Y. Li et al., 2019; Yang et al., 2019). This transition from a passive to active continental margin is now considered to be more likely related to the subduction and accretion of the Mongol-Okhotsk Ocean or Panthalassa Ocean, than the Paleo-Pacific Ocean or the Paleo-Asian Ocean, as previously considered by G.Y. Li et al. (2019). This ocean between the Songliao and Jiamusi Blocks started to close in the end-Paleozoic to late Jurassic as a result of west-directed subduction beneath the Songliao Block and the Zhangguancai Range magmatic arc, which marked a new 305-195 Ma period of accretionary growth. Throughout this period innumerable magmatic plutons were emplaced in the Zhangguancai Range magmatic arc from 294 Ma to 195 Ma (Table 2), as marked by our 245 Ma leucogranite and 211 Ma gabbro (see Parts 7.2.2 and 7.3). Later tectonic erosion of arcs in the Jurassic enabled some sediment to be accreted and some to be removed and subducted to the mantle (see Part 7.8), causing removal of an accretionary wedge and forearc. This process and situation would be similar to the identification of a substantial magmatic arc in Japan, which is now missing, but is identified from eroded and accreted sedimentary molasse (Isozaki et al., 2010, 2011; Maruyama et al., 2011). 44
Similarly, it is well established that there is a paucity of magmatic arcs preserved today in the European Alps, but their former presence may be identified by evaluation of the exhumation and erosion history of the resultant flysch and molasse (e.g. Fox et al., 2016). Moreover, in the Japanese Islands, there is no evidence, as there is in the Swiss Alps, of an oceanward retreat or roll-back of the subduction zone, as recorded in the Zhangguancai Range magmatic arc from an analysis of Permian-Jurassic U-Pb zircon ages of former granitoids and volcanic rocks (Table 2; Fig. 16b). The third phase of this discontinuous accretionary process took place between 195 Ma and 142 Ma, corresponding to an extensive regional episode of tectonic erosion in NE China. The entry into the subduction zone of mid-oceanic ridge at the eastern margin of the Songliao Block after 205-200 Ma may have been triggered by or was a response to the episode of tectonic erosion. Throughout this period the positions of both the trench and magmatic arc front along the Zhangguancai Range magmatic arc retreated together toward the continent for a distance of at least 80-60 Km (Fig. 16a). Simultaneously, a subduction mélange developed at the trench site of tectonic erosion (Isozaki et al., 2011; Maruyama et al., 2011; Suzuki et al., 2010), when subducted Carboniferous Jurassic oceanic rocks and overlying serpentinized mantle and incorporated Cambrian to PermoTriassic fragments of the Songliao Block were off-scrapped with sediments/metasediments sourced from magmatic rocks from either the Jiamusi and Songliao Blocks (see Parts 7.2.2 and 7.2.3; Dong et al., 2018a); this process follows the principles of off-scraping or peeling of oceanic crust in subduction zones such as the extant Nankai Trough in Japan (Kimura and Ludden, 1995). During the subduction-exhumation in the subduction channel the mélange underwent HP metamorphism between 198 Ma and 145 Ma, and following the exhumation it was juxtaposed against the eastern margin of the Zhangguancai Range magmatic arc (see part 7.8).
45
The final amalgamation of the Jiamusi and Songliao Blocks marks a new phase of continental construction either from 180 Ma (Zhou et al., 2009, 2010) or after 140 Ma (Zhu et al., 2015). As recently recorded by Zhu et al. (2015, 2017a, 2017b, 2017c), few protolith ages of metabasalts are dated at 162-142 Ma. Accordingly, the youngest protolith ages suggest that the Mudanjiang Ocean was still open at the end-Jurassic to early Cretaceous, when oceanic material was being accreted and metamorphosed in the subduction mélange. Moreover, the presence of significant age populations of detrital zircons linked to the Zhangguancai Range magmatic arc and the Jiamusi Block, highlight the bi-directional source for the sedimentary materials (see Part 7.2.3; Dong et al., 2018a). The mélange formed during the episode of Jurassic tectonic erosion when these two magmatic terranes were already juxtaposed (Xiao et al., 2017), and ready to provide sediments to the HP Heilongjiang Complex. Thus, the provenance analysis of detrital zircons in the HP Heilongjiang Complex may indicate that the Songliao and Jiamusi Blocks were already on the way to their amalgamation at the end-Jurassic when the “Mudanjiang ocean” was still subducting at 142 Ma. From this view-point, the final closure of the “Mudanjiang ocean” and the arc-arc collision between the Jiamusi and Songliao Blocks was likely at the Jurassic-Cretaceous boundary between 140 Ma and 130 Ma (Ge et al., 2016, 2017, 2018; Zhu et al., 2015, 2017a, 2017b, 2017c, 2017d). The last phase of the accretionary process was linked to a new phase of regional accretionary growth during the Cretaceous, which affected much of NE Asia. This new phase of regional accretionary growth is marked by 112-101 Ma intrusions of subduction-generated granitic and volcanic rocks in the HP Heilongjiang Complex. These post-accretionary 112-101 Ma intrusions can be linked to the eastward regional migration of the arc front between 131 Ma and 100 Ma during the roll-back of the subducted Pacific Plate. This roll-back process gave rise to widespread back-arc volcanism in NE China (Ma et al., 2017; M.D. Sun et al., 2018; Xu et al., 46
2013), which built new accretionary wedges in forearcs (e.g. in the Nadanhanda and Sikhote-Alin terranes) (Khanchuk et al., 2016; Zhou et al., 2014).
7.10. Mesozoic regional extrusion of NE China Northeast-directed extrusion in NE China is documented by several paleogeographic reconstructions, which proposed an early Permian (299 Ma) to late Jurassic-early Cretaceous timespan (Natal’in, 1993; Şengör et al., 2014; 2018; Şengör and Natal’in, 1996). The main mechanism to explain this northeast-ward extrusion was the development of regional ENE/NE-trending transcurrent faults, which transected much of NE China. The structural and geochronological data reported in this paper provide strong evidence that HP Heilongjiang Complex was reworked by sinistral shearing along the ENE/NE-trending network of transcurrent faults (see Part 7.6). In addition, the histogram of the accretionary systems highlights the fact that the sinistral 223-161 Ma and 105-96 Ma movements of the Dunhua-Mishan fault overlap the Mesozoic accretionary and erosion processes linked to the Paleo-Pacific subduction (see parts 7.8 and 7.9; Fig. 15). Notably, the 195 Ma magmatic arc front exhibits 2D sinuous folded patterns that link with the 223-161 Ma sinistral movement on the Dunhua-Mishan fault (Table 2; Fig 16a). With regard to all the above presented geological data, we emphasize that the regional ENE/NE-trending transcurrent faults transected and dissected the whole crustal architecture of the accretionary system. The onset of this process was between 223 Ma and 161 Ma when the sinistral ENE/NE-trending transcurrent faults sliced through the magmatic arc, and may have continued until 96 Ma (C. Liu et al., 2018; Table 2). During the 195-142 Ma emplacement of the HP Heilongjiang Complex as a subduction mélange, regional sinistral transcurrent faults cross-cut the whole accretionary orogen including the accretionary complex and magmatic arc. As a result, the
47
late Triassic to Cretaceous “arc-slice strike-slip process” (Natal’in and Şengör, 2005) duplicated the original crustal structure of the accretionary orogen and likely caused successive repetitions of accretionary complex-magmatic arc fragments along the transcurrent faults (Fig. 18). Notably, the Khanka Block, which corresponds to the southern edge of the Zhangguancai Range magmatic arc was juxtaposed with the Jiamusi Block during this “strike-slip arc slicing” (K. Liu et al., 2018). This scenario plausibly took place when NE China was highly stressed between the North China and Siberian craton during the final closure of the Paleo-Asian and Mongol-Okhotsk Oceans (Natal’in, 1993; Şengör et al., 2014 ; 2018 ; Şengör and Natal’in, 1996). As a response to this final closure of the Paleo-Asian and Mongol-Okhotsk Oceans in the late Triassic (Xiao et al., 2015), part of the segmented accretionary system was forced to extrude toward the northeast between the two major continental cratons from the late Permian to early Cretaceous, when the westward subduction of the Paleo-Pacific Ocean was already operating in NE China (Şengör and Natal’in, 1996; Zhou et al., 2009; Xiao et al., 2015). Before 160-140 Ma, NE China ended its extrusion at the Jurassic-Cretaceous boundary, and collided with the Siberian Craton along the Mongol ‐ Okhotsk suture (Şengör and Natal’in, 1996; Tomurtogoo et al. 2005; Aouizerat et al., 2018).
8. Conclusions •
Structural, geochronological and geochemical analyses were performed on the high-pressure Heilongjiang Complex and on the eastern margin of the Zhanguancai Range Magmatic arc in NE China. Two main periods of oceanward accretionary growth are highlighted between 305 Ma and 195 Ma and around 112-101 Ma, and a regional tectonic erosion affected NE China from 195 Ma to 142 Ma.

•
The whole accretionary system was transected and dissected by regional sinistral ENE/NEtrending transcurrent faults from Triassic to Cretaceous time. This regional deformation was linked to Mesozoic northeast-directed extrusion and exhumation in NE China that formed in response to the final closure of the Paleo-Asian and Mongol-Okhotsk oceans (Şengör and Natal’in, 1996; Xiao et al., 2015).
•
Complementary to the published 308-281 Ma protolith ages on metabasites (Table 4; Fig. 15), a new 356 Ma maximum age of an OIB basalt suggests that the “Mudanjiang ocean” was already in existence in Carboniferous-early Permian time between the Jiamusi and Songliao Blocks, and that is much older than previously proposed.
•
Coupled with a review of the zircon ages from the whole accretionary system, a 245 Ma maximum protolith age on a leucogranite (YIL-LEU-14 sample) and xenocryst population ages in granitic and volcanic rocks in the HP Heilongjiong Complex supply conclusive evidence that the Zhangguancai Range magmatic arc constitutes the main source for early Paleozoic and Permo-Triassic granitic and volcanic rocks within the HP Heilongjiang Complex. The sedimentary rocks within the HP Heilongjiang Complex were sourced either from the Zhangguancai Range magmatic arc or the Jiamusi Block.
•
A deformed adakite-gabbro from the eastern edge of the Zhangguancai Range magmatic arc (YIL-GAB-16 sample) has a weighted mean
206Pb/238U
SIMS zircon age of 211±1 Ma. This
211 Ma gabbro indicates that subduction on the eastern margin of the Songliao Block in the Zhangguancai Range magmatic arc was in operation in the end-Triassic. •
Combined with previous radiometric dating of metamorphic minerals, new 179-76 Ma 40Ar‐ 39Ar
phengite ages from blueschists lenses in the Mudanjiang area (MUD-31 and 39 samples)
49
support a 198-145 Ma time-span of the HP metamorphism that was associated with the exhumation of the HP Heilongjiang Complex. •
175-161 Ma maximum ages of intrusions were obtained on an adakite granitic vein (MUD-37 sample) and an adakitic granodiorite vein (MUD-40 sample), both of which trandsect the HP Heilongiang Complex. The trace element patterns of adakite melts indicate generation by slab melting, which was likely facilitated by the entry of a mid-oceanic ridge into the subduction zone after 205-200 Ma.
•
The 198-145 Ma HP metamorphism was coincident with a regional 195-142 Ma tectonic erosion event, which was triggered by a slightly older entry of a mid-oceanic ridge into a subduction zone at the Triassic-Jurassic transition. During this event numerous components from the eroded Songliao Block were incorporated into the mélange and exhumed with the HP metamorphic rocks (metabasites, metasediments) within the subduction-exhumation channel. In this same period, the magmatic front moved westwards between 195 Ma and 166 Ma as a consequence of the advancing subduction front.
•
The HP Heilongjiang Complex was intruded by a younger arc-generated adakitic leucogranitic dike (YIL-LEU-23), and a monzodiorite (YIL-G-15), and an associated trachyte (YIL-T-2) at ca. 112-101 Ma; these post-accretionary magmatic intrusions and extrusions highlight a new period of regional accretionary growth in the Paleo-Pacific orogenic belt.

Highlights
Two main periods of oceanward accretionary growth are identified in NE China between 305 Ma and 195 Ma and around 112 Ma-101 Ma. A major phase of regional subduction erosion happened between 195 Ma and 142 Ma at the eastern edge of the Songliao Block. An arc-arc collisional process happened amalgamating the Jiamusi and Songliao Blocks in the early Cretaceous. Combined with regional data, we suggest that the regional Jurassic-early Cretaceous extrusion event disturbed the initial orogenic architecture in NE China.
