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

该项目包括在印度与海得拉巴国家地球物理研究所（NGRI）进行的一项强有力的合作被动宽带地震实验。 NGRI将利用他们自己的资金，沿着从海得拉巴北部到喜马拉雅前线的线性剖面沿着部署20台宽带地震仪器。 这项拟议工作的目标是系统地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。 拟议中的线横断大部分的东亚印度次大陆，并将使我们能够解决重大的科学问题，包括前寒武纪的地壳和地幔结构的印度是符合全球太古代岩石圈演化模型。 该样带还将对德干圈闭火山溢流玄武岩区域的深部结构、印度-恒河盆地的形状以及印度在俯冲到南亚之下之前的初始结构提供限制。
