1. Field study of the Central Indian Tectonic Zone and surrounding areas were conducted for two years (1998 and 1999). Twenty seven scientists from Japan worked in India and near by areas for 573 man-days in total, and 40 local geologists coworked for 659 man-days in total. Four India scientists were invited to work in Japan for 133 man-days in total. Field surveys were mostly concentrated in the Aravalli-Delhi belts and central area of the Central Indian Tectonic Zone (CITZ). Eastern area of the CITZ, Eastern Ghats, South Indian Proterozoic Belt, and Sri Lanka were subsidially surveyed.2.New knowledge on the Aravalli-Delhi belts, central area of the CITZ, and the CITZ as a whole were obtained through the present research. Petrological and geochronological data were obtained for rock samples collected through the present field survey. A part of the data was published in international journals.3.Through the present study, the importance of the Central Indian Tectonic Zone in the Gondwan … More a Tectonics has come to be unraveled. Major time of the suturing of the CITZ is considered to be Paleoproteozoic (ca 1.9 - 2.2 Ga), and the zone is considered to have worked as the intracratonic mobile belt in later orogenic periods including the Grenvillian and Pan-African orogenies. Thus, it is considered that the Pinjara Orogen, which fringes the western border of the western Australian cratons is considered to have played an important role in the assembly tectonics of Rodinia during the Grenvillian period (Yoshida, 2001, Gondwana Research 4, 208 - 211).4.Results of the present research project were published/reported in international journals and international symposiums etc. They include 105 papers, 60 presentations and 8 books or special issues of international journals. Editing of 10 local as well as international journals were also conducted through the activity of the project. The summary of the fruit of the present research project was published as an English book, titled "The Central Indian Tectonic Zone and its Extensions within East Gondwana (GRC/GIGE Misc. Pub., 14) This volume is composed of 4 chapters including Tectonics of the Central Indian Tectonic Zone (155 pages with 11 papers), Tectonics of the Aravalli-Delhi mobile belts (66 pages with 7 papers), Tectonics and Petrology of Proterozoic Mobile Belts of Eastern India (79 pages with 8 papers), and Tectonics and Petrology of South Indian Shield (47 pages with 6 papers). Appendixes of 1) lists of publications and presentations born out from the project, and 2) a bunch of copies of files formally submitted to the Japan Ministry of Education, Science, Sports and Culture (MONBUSHO) (mostly in Japanese) are also included.

1.对中印度构造带及其周围地区进行了为期两年的实地研究(1998年和1999年)。来自日本的27名科学家在印度及其附近地区总共工作了573个工日，当地40名地质学家总共合作了659个工日。四名印度科学家被邀请到日本工作，总共133个工日。野外调查主要集中在阿拉瓦利-德里带和中印度构造带(CITZ)的中心地区。2.通过本次研究，对阿拉瓦利-德里带、CITZ中心区以及整个CITZ有了新的认识。通过本次野外调查获得了岩石样品的岩石学和地质年代学数据。部分数据发表在国际期刊上。3.通过本研究，中印度构造带在贡德万…中的重要性更多的是一种构造学的解体。CITZ的主要缝合时间被认为是古元古代(约1.9-2.2Ga)，该带被认为是造山期后期的克拉通内活动带，包括格伦维利亚造山和泛非造山。因此，位于西澳克拉通西缘的平扎拉造山带被认为在格伦维利亚时期的Rodinia组装构造中发挥了重要作用(Yoshida，2001，Gonwaana Research 4,208-211)。4.本研究项目的成果发表/报道在国际期刊和国际研讨会等上，包括105篇论文、60篇演讲和8本书或国际期刊的专刊。通过该项目的活动，还编辑了10份地方和国际期刊。本研究项目的成果摘要以英文书的形式出版，书名为“中印度构造带及其在东冈瓦那的延伸”(GRC/GigE Misc。这一卷由4章组成，包括中印度构造带的构造学(155页，共11篇论文)，阿拉瓦利-德里活动带的构造学(66页，7篇论文)，东印度元古代活动带的构造学和岩石学(79页，8篇论文)，南印度盾的构造学和岩石学(47页，6篇论文)。附录包括1)该项目产生的出版物和演示文稿清单，以及2)一批正式提交给日本文部省(文部省)的文件副本(主要是日语)。较少
