Description: This project supports collaboration by Dr. Gilbert Hanson of State University of New York (SUNY) at Stony Brook with Dr. V. Rajamani of Jawaharlal Nehru University (JNU) in New Delhi on geochemical study of the Eastern Dharwar Craton (EDC) in South India. The study is aimed at a hypothesis that the EDC is made up of accretionary terranes and that gold mineralization occurred associated with accretion of the terranes. If there are different terranes, it is intended to determine the histories of the rocks within the various terranes and determine the timing of their assemblage. The field work will continue geological studies in the Ramagiri Schist Belt, and begin studies of the Hutti-Maski Schist Belt 500 Km north of the Kolar Schist Belt along regional structural trend. The work will include collecting samples by the U.S. and Indian scientists in the field, to be followed by chemical analysis mainly at the SUNY laboratory by the U.S. and Indian co-investigators. Some of the chemical analysis will be done at JNU by Dr. Rajamani and his students. Scope: This project is building on a well-established working relationship by the two scientists. They have several joint publications as a result of their previous work. This project is likely to continue this productive scientific cooperation. U.S. Graduate students and post doctorates, from the SUNY at Stony Brook, are involved in the field work, and are expected to gain experience in international research efforts.

描述：该项目支持纽约州立大学石溪分校的Gilbert Hanson博士与新德里贾瓦哈拉尔·尼赫鲁大学(JNU)的V.Rajamani博士在南印度东部达瓦尔克拉通(EDC)的地球化学研究上的合作。这项研究旨在提出EDC是由增生地体组成的假说，并认为金矿成矿作用与地体的增生有关。如果有不同的地体，它的目的是确定不同地体中岩石的历史，并确定它们的组合时间。野外工作将继续对Ramagiri片岩带进行地质研究，并开始沿区域构造走向对科勒片岩带以北500公里处的Hutti-Maski片岩带进行研究。这项工作将包括由美国和印度科学家在该领域收集样本，然后由美国和印度的联合调查人员主要在纽约州立大学的实验室进行化学分析。一些化学分析将由拉贾马尼博士和他的学生在JNU完成。范围：这个项目是建立在两位科学家良好的工作关系之上的。由于他们之前的工作，他们有几份联合出版物。该项目很可能会继续这种富有成效的科学合作。来自纽约州立大学石溪分校的美国研究生和博士后参与了实地工作，并有望获得国际研究工作的经验。
