Description: This project supports research by Dr. Bhattacharji and scientists from Louisiana State University, Florida State University, University of Rhode Island, Kansas State University and Queens College in New York in collaboration with geologists from the Geological Survey of India (GSI), under the direction of D.P. Dhondial the Director General of GSI. The research will include field work in central India along a lineament belt, and will include geochemical and geochronological studies in laboratories at U.S. universities. The objectives are: determination of the tectonic evolution of the inta-plate lineament belt and the relationship to associated flood basalts; delineation of the evolutionary paths of the mafic and ultramafic dikes and dike swarms; determination of the chemical and isotopic nature of the parental magmas, study of the hot spot hypothesis for intra-plate magmatism; and development of a thermo-mechanical model for the evolution of the lineament belt. Scope: The topic of this research was developed through a joint field workshop held in India which identified the specific lineament as suitable for providing the needed data. The work was started in the field and some laboratory investigations were carried out. A program report was produced which showed interesting results and pointed to the importance of geochronologic and petrogenic studies of the areas visited. The research project has the full backing of the Government of India, and enables a large number of U.S. scientists to work with their Indian colleagues on field investigations in India. It allows the Indian scientists to visit the U.S. for participation in the laboratory testing of samples. The collaboration is particularly useful to the two sides.

描述：该项目支持Bhattacharji博士和来自路易斯安那州立大学、佛罗里达州立大学、罗德岛大学、堪萨斯州立大学和纽约皇后学院的科学家与印度地质调查局(GSI)的地质学家在GSI总干事D.P.Dhonial的指导下进行的研究。这项研究将包括沿着一条线带在印度中部进行的实地工作，还将包括在美国大学的实验室进行的地球化学和地质年代学研究。其目的是：确定板块间线形构造带的构造演化及其与溢流玄武岩的关系；划定镁铁质和超镁铁质岩脉和岩墙群的演化路径；确定母岩浆的化学和同位素性质；研究板内岩浆活动的热点假说；并开发了线形构造带演化的热力学模型。范围：这项研究的主题是通过在印度举行的联合实地讲习班确定适合提供所需数据的具体线型而展开的。这项工作是在实地开始的，并进行了一些实验室调查。编写了一份方案报告，其中显示了有趣的结果，并指出了对所访问地区进行地质年代学和岩石学研究的重要性。该研究项目得到了印度政府的全力支持，使大量美国科学家能够与他们的印度同事一起在印度进行实地调查。它允许印度科学家访问美国，参加样品的实验室测试。这种合作对双方来说特别有用。
