Extensional Faulting Within the Convergent Himalayan Region

在会聚造山带内，一般不观察到大量同方向的同步伸展和压缩。这些都是在整个区域受到压缩的同时形成的。该项目是一项研究的延续，通过绘图和随后的时间、运动感和位移分析来记录这些故障。研究结果有望为解释和构建大陆碰撞构造中正断层作用的动力学模型提供必要的数据。这项工作是与成都地质矿产研究所和北京地质部合作进行的。

Within convergent orogenic belts, significant amounts of synchronous extension and compression in the same direction are not generally observed. However, it has been recently recognized that East-West striking, gently north-dipping normal faults of regional extent exist in and north of the High Himalayas and in Ladakh. These are forming at the same time the entire region is undergoing compression. This project is continuation of a study to document these faults by mapping and subsequent analysis of timing, sense of motion and displacement. Results are expected to provide data necessary to interpret and construct dynamic models of the role of normal faults in continental collision tectonic situations. This work is cooperative with the Chengdu Institute of Geology and Mineral Resources and the Ministry of Geology in Beijing.
