Tectonics of Central Indian Tectonic Zone-Study of Proterozoic Events in East Gondwana

1. 对印度中部构造带及其周边地区进行了为期两年（1998年和1999年）的野外研究。27名日本科学家在印度及附近地区共工作了573个工作日，40名当地地质学家共同工作了659个工作日。四名印度科学家被邀请到日本工作，总共133个工作日。野外调查主要集中在Aravalli-Delhi带和中印度构造带（CITZ）的中部地区。对北京特区东部地区、东高止山脉、南印度元古代带和斯里兰卡进行了辅助调查。通过本文的研究，对Aravalli-Delhi带、CITZ中心区和整个CITZ有了新的认识。通过这次野外调查收集的岩石样品获得了岩石学和地质年代学数据。部分数据发表在国际期刊上。通过本文的研究，揭示了中印度构造带在冈万构造中的重要性。古元古代（约1.9 ~ 2.2 Ga）是该区的主要缝合时期，在格林尼治造山期和泛非造山期，该区曾是克拉通内活动带。因此，认为位于西澳大利亚克拉通西部边界的Pinjara造山带在Grenvillian时期的Rodinia组合构造中发挥了重要作用（Yoshida, 2001, Gondwana Research 4,208 - 211）。本课题研究成果已在国际期刊、国际学术会议等发表。其中论文105篇，演讲60篇，专著或国际期刊特刊8本。通过该项目的活动，还编辑了10份当地和国际期刊。本研究项目的成果总结以英文书的形式出版，题为“印度中部构造带及其在东冈瓦纳的延伸（GRC/GIGE Misc）”。酒吧。本卷共分为4章，分别是：印度中部构造带构造学（155页，11篇论文）、阿拉瓦利-德里活动带构造学（66页，7篇论文）、东印度元古代活动带构造与岩石学（79页，8篇论文）、南印度盾构造与岩石学（47页，6篇论文）。附件包括：1)该项目产生的出版物和演示清单，以及2)正式提交给日本文部科学省（MONBUSHO）的一堆文件副本（主要是日语）。少

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.
