54. DIXON, JM UNIV. CONNECT ICUT, STORES, USA A new method of determining finite strain in models of geological structures. 6F,2T, gR. TECTONOPHYSICS, V24, N1- 2,1974, P99-114. A new method of constructing models of cylindrical geological structures has been developed which allows the finite strain to be determined for each of a large number of small, initially square, elements. As an exa~le, the method is applied to a silicone putty model of a diapivic ridge which was formed by spinning the model in a centrifuge.
55. SAUER, EK Geotechnical implications of Pleistocene deposits in Southern Saskatchewan. 15F,1T,24R. CAN.GEOTECH. J.Vll, N3, AUG. 1974, P359-373. Some of the geotechnical problems in Saskatchewan-slope instability, groundwater control, location of gravel aggregates and excavation and handling of embankment materials,can mow be fundamentally related to Pleistocene stratigraphy. Examples ere presented to illustrate this approach. Special criteria are required in order to establish a true stratigraphic colu,m in terms of reference sections, for any one site. These criteria ere obtained by the Use of rotary drilling and geophysical logging, and ere described in the paper, with examples.
Mechanism of faulting and folding 56. BOOKER,JR UNIV .WASHINGTON, SEATTLE, US A Time dependent strain following faulting of a porous medium. 4F,22R. J .GEOPHYS .RES .V79, NI4,1974,1>2037-2044. The Biot theory is used to calculate tlme-dependent stress, strain and pore pressure fields after a plane failure whose offset varies sinusoldally in the direction of slip. The results ere used to construct an erbitrary one-dimenslonal sllp function by Fourier synthesis. The case of a simple crank made from two edge dislocations is particularly considered.
Tectonic stress and strain 57. RALEIGH, CB Crustal stress end global tectonics .-Report. In Advances in Pock Mechsmies Vi,Pert A. In English, French and German. 4F,16R. PROC .3RD CONGRESS INT .SOC .ROCK MECH .SEPT. 1974, DENV~, USA, NAT. ACAD. SC I .VI, PART A,1974, P593-610. The earths surface is divided into large plates of the crust and upper mantle which move relative to each other at a few centimeters per year, and the boundaries of these plates form regions of intense tectonic activity. The driving mechanism for this plate movement is poorly understood although orientations of stress fields at points within the plates rosy provide evidence for the mechanism of plate motion. Compilations of earthquake focal mechanism solution and in-situ stress measurements for the Western United States show good agreement between the two.
58. ~-JR,A Tectonophysics: the study of relations between deformation and forces in the earth - General report. In Advsmces in Pock Mechanics V1,Part A. In ~%glish, French and Ger~mJa. 73F,6T,224R. PROC.3RD CONGRESS INT.SOC.ROCK MECH.SEPT.1974, D ~ V ~ , USA, NAT. ACAD. SC I .VI,PART A,1974,P243-483. In this general report tectonophysical processes ere divided into three groups according to the region in which they occur: the upper crust, lower crust and mantle. In the upper crust deformation is concentrated along faults and takes the form of sllp or creep. In the lower crust ductile deformation caused by increasing confining pressure, or change in mineralogy, is prevalent. In the mantle deformation involves most probably high te~ioerature creep. The evidence for and processes in. volved in these movements, are summsrised in three ~ o r chapters each relating to one of the three major regions indicated above.
59. MA~'gHEWS, PE UNIV .NATAL, DURBAN, ZA BOND, RA UNIV .NATAL, DURBAN, ZA VAN DEN B~RG,JJ UNIV,NATAL, DURBAN,ZA An algebraic method of strain analysis using elliptical markers. 12F,3T,19R. TECTONOPHYS ICS, V24, N1- 2,1974, I>3l-67. A new method is described for finite strain analysis of naturally deformed sub-fabrics of elliptical markers assuming an homogeneous deformation on the scale of the sample. The method is numerical, and relies on derived equations which relate the axial ratios and orientations of elliptical markers to algebraic parameters of finite linear transformations. Auth. 60. LLIBOL~IRY, L UNIV. GR~Z~OBLE,F Rheological properties of lithosphere. 4F,2T,8R. TECTONOP~fSICS,V24, NI- 2,1974, P13-29. The flexure of the lithosphere under a linear load, such as at Hawaii, and before a trench, such as in the Hokkaido rise - Kurll trench system, ere calculated assuming homogeneous visco-elasticity and (in the second case) a superimposed longitudinal compression.
