US-India Cooperative Research: Thermo-tectonic Evolution of the Himalayan Metamorphic Rocks, Sikkim, India

该奖项支持美印合作研究：锡金喜马拉雅变质岩热构造演化。美国亚利桑那大学的Pi Jibamitra Gangully和加尔各答贾达夫布尔大学的Somnath Dasgupta将研究沿喜马拉雅山脉2000公里长的倒转变质巴罗维亚序列的存在。在印度-欧亚板块碰撞的框架内考虑喜马拉雅变质作用的研究，并不能令人满意地解释巴罗纪等值线的反转。PIS将在这项研究中使用综合方法，包括现场关系、岩石学研究、实验室研究和数值模拟。范围：国际合作对本研究非常有利。达斯古普塔教授是印度一位杰出的学者和杰出的野外地质学家。他最近的工作发表在《岩石学杂志》(1998)上，这是对理解喜马拉雅构造变质过程的重大贡献。NSF的国际项目部和印度政府的科学技术和地质调查局共同支持这项研究。

0002004Ganguly Description: This award supports US-India Cooperative Research: Thermo-tectonic Evolution of the Himalayan Metamorphic Rocks, Sikkim. US PI Jibamitra Ganguly, University of Arizona and Somnath Dasgupta, Jadavpur University, Calcutta will study the presence of an inverted metamorphic Barrovian sequence along the 2000-km length of the Himalayas. Studies which consider the Himalayan metamorphism within the framework of the Indian-Eurasian plate collision have not satisfactorily explained the inversion of the Barrovian isograds. The PIs will use an integrated approach in this study that includes field relations, petrographic studies, laboratory studies and numerical modeling. Scope: The international collaboration is highly advantageous to this study. Professor Dasgupta is a distinguished scholar and a preeminent field geologist in India. His recent work that was published in the Journal of Petrology (1998) is a major contribution to understanding tectono-metamorphic processes in the Himalayas. NSF's Division of International Programs and the Government of India's Department of Science and Technology and Geological Survey jointly support this research.
