• 关键词: paleoposition of the Indian Peninsula; paleomagnetism at the Godavari and the Mahanadi Grabens; Gondwana sediments

The aim of this survey is to clarify the relative paleoposition of the Indian Peninsula to the other continental masses, especially to the Antarctica, and its change with time by the study of paleomagnetism at the Godavari and the Mahanadi Grabens. Not only the Gondwana sediments of the Mesozoic the Archean and the Proterozoic basement rock are distributed at these grabens.We discussed with the Geological Survey of India (GSI) who are the counterpart of this survey, and confirmed that this survey is promoted as an India-Japan scientific cooperative program partly supporting the International Geological correlation Program (IGCP) no. 288.The field survey was undergone first in the Godavari region from 21st through 29th, October, with the collaboration of GSI Hyderabad, and then in the Mahanadi region from 31st, October through 5th, November with cooperation of GSI Bhubaneswar and Calcutta.Since this proposal is accepted as a one year reconnaissance survey for 1991, we tried to collect as many kinds of rocks as possible in both of the regions to eliminate what kind of rocks is suitable for paleomagnetic measurements.As the result of field sampling, we obtained 501 oriented paleomagnetic samples from 56 sites. Rock kinds of the samples are sandstone, siltstone, limestone, dolomite, basalt, dolerite dyke, granite, pegmatite, migmatite, gneissose granite, khondalite, chernockite, quatzite, schist and phillite.

这项调查的目的是阐明印度半岛与其他大陆群体的相对古适处，尤其是对南极洲的群众，以及通过研究Godavari和Mahanadi抓住的古势症的时间而变化。在这些抢劫中分发了中生代的冈瓦纳沉积物和properorokoic地下室岩石。我们与印度地质调查局（GSI）讨论了这项调查的同行，并确认这项调查被提升为印度 - 日本科学合作计划的一部分支持国际地质跨越国际地质Corelation noo（igcp）。 288.现场调查首先在10月21日至29日在Godavari地区进行，与GSI Hyderabad的合作，然后在11月31日至11月5日在Mahanadi地区进行了合作在消除哪种岩石适合古磁测量的区域中。由于田间采样的结果，我们从56个地点获得了501个方向的古磁样品。样品的岩石是砂岩，粉砂，石灰石，白云岩，玄武岩，多叶岩堤坝，花岗岩，pegmatite，migmatite，Migmatite，Gneissose Granite，Khondalite，Khondalite，Chernockite，Chernockite，Chernockite，Quatzite，Quatzite，Quatzite，Schist和Phillite。
