A Deep Seismic Reflection of the Himalaya/Tibet Plateau Collision Zone: Phase 1: Pilot Survey

该项目将实施一项为期多年的国际合作项目的初始阶段，该项目旨在收集喜马拉雅/西藏高原碰撞带的深部地震反射数据，这是大陆-大陆碰撞的典型例子。该项目的目标是描绘在碰撞过程中演化的西藏岩石圈的主要结构特征，并通过这一特征对整个大陆岩石圈演化的理解作出实质性贡献。在项目的初始阶段，主要研究人员打算与中华人民共和国地质和矿产资源部（MGMR）合作，进行一次大约100公里长的测试调查，以便(1)确定在这一独特地区进行深反射剖面分析的后勤要求；(2)解决与高原演化有关的关键地质问题。这一初步测试是在喜马拉雅/西藏高原地区进行全面分析的重要前奏。

This project will implement the initial phase of a multi-year, international cooperative project to collect deep seismic reflection data across the Himalaya/Tibet Plateau collision zone, the type example of a continent-continent collision. The goal of the project is to delineate the major structual features of the Tibetan lithosphere that have evolved during the collision process, and through this contribute substantially to an understanding of the evolution of continental lithosphere as a whole. During the initial phase of the project the principal investigators intend to carry out, in cooperation with the Ministry of Geology and Mineral Resources of the People's Republic of China (MGMR), a test survey of approximately 100 km length in order to (1) define the logistical requirements for deep reflection profiling in this unique area, and (2) address a key geologic problem relating to the evolution of the plateau. This initial test is an essential prelude to full scale profiling across the Himalaya/Tibet Plateau region.
