US-India Coop Res: Structure & Evolution of the South Indian Craton & Mobile Belts from Deep Seismic Profiling & other Geophysical & Geological Investigations: A LE

该奖项支持美印合作研究项目《南印度克拉通和活动带的结构和演化--来自深部地震剖面图和其他地球物理和地质调查：一个传奇倡议》。美国康奈尔大学的Pi David Brown和印度国家地球物理研究所(NGRI)的印度合作者Parvata R.Reddy将在南印度克拉通作为超大陆关键碎片之一的背景下研究其深部地壳和岩石圈结构，该超大陆被称为冈瓦瓦兰。他们将评估来自印度的现有地球物理数据，并优先处理印度南部岩石圈所代表的关键科学问题。他们还将设计一项在印度南部进行现代地球物理和地质调查的战略计划，该计划最终将作为更大的传奇计划的一部分实施，该计划将探测东冈瓦那大陆碎片的岩石圈。这一努力将为大陆演化的关键方面提供新的见解，例如下地壳和上地幔碰撞缝合的性质、碰撞和伸展结构在岩石圈尺度上的时空相互作用，以及在一系列大陆维度上的岩石圈定义。该项目不仅将促进美国和印度科学家之间的新合作，还将促进与东非邻近冈瓦那国家、马达加斯加和斯里兰卡的科学家之间的新合作。这项研究得到了印度科技部在NSF/DST联合计划下的支持。

This award supports a US-India cooperative research project entitled Structure and Evolution of the South Indian Craton and Mobile Belts from Deep Seismic Profiling and other Geophysical and Geological Investigations: A LEGENDS Initiative. US PI David Brown, Cornell University and Indian collaborator Parvata R. Reddy, National Geophysical Research Institute (NGRI), Hyderabad will investigate the deep crustal and lithospheric structure of the South Indian craton in the context of its role as one of the key fragments of the supercontinent, know as Gondwanaland. They will assess existing geophysical data from India and prioritize the critical scientific issues represented by the lithosphere of southern India. They will also design a strategic program of modern geophysical and geological surveys in southern India that will ultimately be implemented as part of the larger LEGENDS initiative, which will probe the lithosphere of the East Gondwana continental fragments. This effort will offer new insight into key aspects of continental evolution such as the nature of collisional sutures in the lower crust and upper mantle, the space-time interaction of collisional and extensional structures on the lithospheric scale, and the definition of the lithosphere across a range of continental dimensions. This project will promote new collaborations not only between US and Indian scientists but with scientists from the neighboring Gondwana countries of East Africa, Madagascar and Sri Lanka. This research is supported by the Indian Department of Science & Technology under the NSF/DST joint program.
