Crustal Genesis and Mineralization in the Eastern Dharwar Craton, South India, Award in U.S. and Indian Currencies

该项目支持印度新德里贾瓦哈拉尔尼赫鲁大学（JNU）的V. Rajamani博士和纽约州立大学石溪分校的G. Hanson博士的合作研究。这项研究继续了先前在科拉片岩带上所做的工作，并开始了对科拉片岩带北部的拉马吉里和卡迪里片岩带的研究。前人的研究认为，科拉片岩带是将两个地质历史不同的太古宙片麻岩地体分隔开来的缝合线。在带内，东西两侧的角闪岩具有不同的同位素和不相容元素特征，表明它们的发育具有独立的来源。建议的研究将试图研究邻近的带，以了解导致这些带目前组成和形成的构造过程。众所周知，该地区有具有经济意义的矿藏。范围：JNU和纽约州立大学石溪分校的两个团队在之前的NSF资助下合作了几年，取得了相当大的成功，并发表了重要的成果。这一工作也构成了两所大学几名博士生的研究论文。这个项目很有可能继续这种强有力的、富有成效的合作。资助：本项目由两项拨款资助：JNU新德里：FY89 $91,143印度卢比2。纽约州立大学石溪分校：89财年10,571美元印度卢比+ 13,800美元90财年11,143美元印度卢比+ 13,800美元91财年11,714美元印度卢比+ 13,800美元

Description: This project supports collaborative research by Dr. V. Rajamani, Jawaharlal Nehru University (JNU) New Delhi, India and Dr. G. Hanson, SUNY, Stony Brook, NY. The research continues work done previously on the Kolar Schist Belt, and begins studies of the Ramagiri and Kadiri Schist Belts to the north of the Kolar Schist Belt. Previous studies suggest that the Kolar Schist Belt is a suture which separates two Archean gneiss terranes with different geologic histories. Also within the belt the amphibolites from the eastern and western sides have different isotopic and incompatible element characteristics suggesting their development from independent sources. The proposed studies will attempt to study the adjacent belts to learn of the tectonic processes leading to the present composition and formation of these belts. The area is known to have mineral deposits of ecomonic significance. Scope: The two teams from JNU and SUNY Stony Brook have collaborated for several years under previous NSF grants with considerable success and with significant resulting publications. That work has also formed the research dissertations for several Ph. D. students at both institutions. It is highly likely this project will continue this strong, productive cooperation. Funding: This project is being funded under two grants: 1. JNU New Delhi: FY89 $91,143 in Indian rupees 2. SUNY Stony Brook: FY89 $10,571 in Indian rupees + US $13,800 FY90 $11,143 in Indian rupees + US $13,800 FY91 $11,714 IN Indian rupees + US $13,800
