Active Tectonics, Rate of Convergence, and Earthquake Recurrence in the Tien Shan

本项研究是为了研究一个高度活跃的逆冲断层中的变形 构造背景，中国西部天山地区。 地壳 整个山脉的缩短主要是由逆冲断层造成的。 这项研究将使用经典的地表地质测绘， 结构来估计整个范围内的缩短量。 由于晚新生代沉积岩是褶皱的，因此边界 缩短的量将产生的速度界限， 变形 绘制变形地表岩石的几何图形将 约束模型的地下形状的更深的断层。 本文所获得的知识将应用于逆冲变形 美国的政权，如南部的横贯山脉， 加州。 这项研究是国家 减少地震灾害计划。

This research is to study deformation in a highly active thrust tectonic setting, the Tien Shan region in Western China. Crustal shortening across the range occurs largely by thrust faulting. The study will use classical geologic mapping of surface structures to estimate amounts of shortening across the range. Because Late Cenozoic sedimentary rocks are folded, bounds on the amounts of shortening will yield bounds on the rates of deformation. Mapping the geometry of deformed surface rocks will constrain models of the subsurface shapes of the deeper faults. Knowledge gained here will be applied to thrust deformation regimes in the U.S. such as the Transverse Ranges of Southern California. This research is a component of the National Earthquake Hazard Reduction Program.
