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

0002004 Ganguly描述：该奖项支持美印合作研究：锡金喜马拉雅变质岩的热构造演化。 美国亚利桑那大学PI Jibamitra Ganguly和加尔各答Jadavpur大学的Somnath Dasgupta将研究喜马拉雅山脉沿着2000公里长的反转变质Barrovian层序的存在。 把喜马拉雅变质作用纳入印度-欧亚板块碰撞框架内的研究不能令人满意地解释巴罗等梯度线的反转。 PI将在本研究中使用综合方法，包括现场关系、岩相学研究、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杰出的学者和杰出的野外地质学家。他最近发表在《岩石学杂志》（1998年）上的工作是对理解喜马拉雅山构造变质过程的重大贡献。 美国国家科学基金会国际项目部和印度政府科学技术部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.
