deformation in the humites, which in turn will reflect in its non-stoichiometry. TEM studies on the humites are therefore essential to document the deformational features, but such studies have been few and far in
between. These studies are expected to yield significant information on the processes operating along a major transcontinental ductile shear zone like the ASZ. It will help in precisely identifylng the fluid processes and nano-scale deformation that minerals undergo during shearing. In areas where shear indicators are sparse, such nano-scale features and concomitant non-stoichiometry may serve as palaeoshear indicators.

General Scientific Achievements of IGCP-368 (October 1998 to October 1999) IGCP-368 conducted an international seminar and field workshop in Central India in October-November 1998, and collaborated in the regional symposium and field workshop “Orogenesis on the Outback” in central Australia in July 1999. We also joined several other symposia including the EUG 10 in Strassbourg in March 1999, 8th International symposium on Antarctic Earth Sciences in Wellington in July 1999, and some other local
symposia in various parts of the world. Another major activity is an International Seminar and Field Workshop in central China in October 1999 where important scientific contributions of the Gondwanaland fragments in Asia came out. Abstract volumes and proceedings of these m e e t i n g s are a p p a r e n t m a j o r scientific achievements of the project. In addition to the above, members of the project contributed much to the creation of new data and ideas related to the project topics, which were published in various international, regional and local journals.

by the project are mostly related to researches in the Madagascar-India-Antarctic sector of East Gondwana as follows. a) Japan-India-Russia joint research program on geochronology of Peninsular India and its comparison with Antarctica and Laurasia started in December 1995 and has continued in 1999. b) Japan-India joint research project on Central Indian Tectonic Zone of India was conducted in 1998 and 1999. An international seminar and field program were conducted in October-November 1998. c) A joint field program in northwestern India was conducted in December 1998-January 1999, and again in late 1999. d) Botswana-Japan joint research program of three years focusing on the Kibaran orogeny in central south Africa is scheduled to start in October 1999. This program will include a student and scientists from Africa and Japan. e) Japan-China collaboration started in April 1998 and will continue some years. It aims to study the signature of Gondwanan crustal fragments and tectonics of their amalgamations.

Other Achievements of the Project in 1999 A. Exchange of informations: Publication and distribution of Gondwana News Letter (Nos. 12 and 13) and an IGCP-368 news letter (Dec. 1998). Meetings related with the project listed above also facilitated the exchange of ideas and information with regard to specific topics among international scientists. B. International joint researches in 1999: International .joint research programs borne out from or encouraged
264
by the project are mostly related to researches in the Madagascar-India-Antarctic sector of East Gondwana as follows. a) Japan-India-Russia joint research program on geochronology of Peninsular India and its comparison with Antarctica and Laurasia started in December 1995 and has continued in 1999. b) Japan-India joint research project on Central Indian Tectonic Zone of India was conducted in 1998 and 1999. An international seminar and field program were conducted in October-November 1998. c) A joint field program in northwestern India was conducted in December 1998-January 1999, and again in late 1999. d) Botswana-Japan joint research program of three years focusing on the Kibaran orogeny in central south Africa is scheduled to start in October 1999. This program will include a student and scientists from Africa and Japan. e) Japan-China collaboration started in April 1998 and will continue some years. It aims to study the signature of Gondwanan crustal fragments and tectonics of their amalgamations.
Proposed Activities of the Project for the Year Ahead 1) General goals
A. To improve knowledge on the Mesoproterozoic to early Palaeozoic events in East Gondwana. B. To improve knowledge about Gondwanan fragments in Asia. C. To improve knowledge about the Central Indian Tectonic Zone to understand the Mesoproterozoic tectonics of East Gondwana and Rodinia. 2) Meetings andfield trips of IGCP 368
A. 28th March, 1999 Symposium on the Assembly and Dispersion of Gondwana and Growth of Asiatic Continent, jointly sponsored by Japan working groups of IGCP-368,411 and 440. B. 8th July, 1999 Business meeting of IGCP-368, during
the 8th International Symposium on Antarctic Earth Sciences, at the Victoria University of Wellington, Wellington, New Zealand. C. 15th July, 1999 Business Meeting of IGCP-368, during the Orogenesis in the Outback, Alice Springs. D. 12-22 July, 1999 Symposium and field excursions as part of Orogenesis in the Outback, co-sponsored by Specialist Group in Geochemistry, Mineralogy and Petrology, Australian Geological Society and IGCP-368, Alice Springs, central Australia. E. 14th September 1999, Business Meeting of IGCP-368, during the I1 Symposium on South American Isotope Geology, Villa Carlos Paz, Cordoba, Argentina. E 10 - 20 October, 1999 Geodynamic and Tectonic Evolution of China and Related Gondwanan Crustal Fragments: International Symposium and Field Workshop, UNESCO-IGCP-IUGS 368/411/440, Yichang, Hubei, China. G. 13th October, 1999 Business Meeting IGCP-368, during the International Symposium, Yichang, China. H. 15th October, 1999 IAGR and joint IGCP-368/411/440 Meeting, during the International Symposium, Yichang, Hubei, China. I. 27-30 June, 2000 Symposium on the Western Pacific Geodynamics Meeting, Tokyo. A joint IGCP-368/411/ 440 session on “Rodinia to Asia through Gondwana” is planned to be conducted. J. 6-17 August, 2000 31st IGC, General Symposium (97) of “Proterozoic Events in East Gondwana” in Rio De Janeiro. The project wishes to support some scientists from developing countries, if the fund is available. K. Field workshop and International symposium in Saudi Arabia. The project wishes to support some scientists from developing countries, if funds are available. 3) Request for extension of IGCP-368 for two more years
The Project IGCP-368has sought two years’ extension/ on-extended-term-studies. We plan to conduct the meetings in 2000 as mentioned above, and also, an important summary symposium in October 2001 in Osaka, when the summary volume of the scientific outcome will be brought out.
