This project involves a five-year multidisciplinary study of the Neogene, Quaternary and active deformation of the Longmen Shan and Sichuan Basin, located along the eastern margin of the Tibetan plateau. This study, to be conducted jointly by scientists at MIT and at the Chengdu Institute of Geology and Mineral Resources in China, will consist of: 1) Field mapping of older structures to determine the Cenozoic tectonic evolution along the Longmen Shan and adjacent areas; 2) A neotectonic study of young and active faults in this portion of the plateau margin; 3) An 11-site GPS network to establish a map of active crustal strain within the area; and 4) A geological and geophysical (flexural and gravity) study of the Sichuan basin. The wide variety of techniques with which the Principal Investigators plan to address this problem will complement and enhance one another, and thereby provide the most complete picture of regional deformation possible. The immediate goal of this project is to document the Cenozoic deformation history of the eastern margin of the Tibetan plateau, but the broadest aim of the project is to develop a better understanding of the nature of intracontinental deformation in Tibet, China and southeast Asia.

该项目涉及一项为期五年的多学科研究， 龙门山新近纪、第四纪及活动变形 陕、川盆地，位于沿着东缘， 青藏高原。 这项研究将由以下机构联合进行： 麻省理工学院和成都地质研究所的科学家们， 中国矿产资源，将包括：1）实地测绘 决定新生代构造演化的古老构造 沿着龙门山及邻区新构造研究 高原边缘的年轻活动断裂; 3)建立活动地壳图的11站GPS网 应变; 4）地质和地球物理 （挠曲和重力）研究。 宽 主要研究者计划使用的各种技术 解决这一问题将相辅相成， 从而提供最完整的区域性 可能变形。 该项目的近期目标是 记录东缘新生代变形史 但该项目最广泛的目标是 更好地了解大陆内部的自然现象 变形在西藏，中国和东南亚。
