The Lithospheric Structure of the Indian Subcontinent

该项目包括与位于海得拉巴的国家地球物理研究所(NGRI)在印度进行的一项强烈合作的被动宽带地震实验。NGRI将使用他们自己的资金，沿着从海得拉巴北部到喜马拉雅前线的线性剖面部署20台宽带地震仪器。这项拟议工作的目标是系统绘制印度岩石圈结构图，并与NGRI地震学家建立长期合作计划。这条拟议的线横跨了印度克拉通次大陆的大部分地区，将使我们能够解决重大科学问题，包括印度的前寒武纪地壳和地幔结构是否与太古代岩石圈演化的全球模型一致。该横断面还将对德干陷阱火山洪水玄武岩区的深层结构、印度河-恒河盆地的形状以及印度俯冲到南亚之下之前的初始结构提供约束。该项目正与国际项目共同资助

This project consists of a strongly collaborative passive broadband seismic experiment in India with the National Geophysical Research Institue (NGRI) in Hyderabad. NGRI will use their own funding to deploy 20 broadband seismic instruments along a linear profile from Hyderabad north to the Himalayan Front. The objectives of this proposed work are a systematic mapping of the Indian lithospheric structure and the establishment of a long-term collaborative program with NGRI seismologists. The proposed line transects large portions of the cratonic Indian subcontinent and will allow us to address major scientific issues including whether the Precambrian crustal and mantle structure of India is consistent with global models of Archean lithospheric evolution. The transect will also provide constraints on the deep structure of the Deccan Trap volcanic flood basalt region, the shape of the Indus-Ganges basin, and the initial structure of India prior to its subduction beneath southern Asia.This project is being co-funded with International Programs
