中国西部活动地块运动模型的建立及其运动学分析

Abstract

Abstract: The neotectonic deformation is very strong along the Tibet and Xinjiang zone distributed in Western China. Nevertheless all the observed data of seismology and geology suggested that this area more possibly consists of several rigid blocks: the Tarim (TM), the Alashan (AS), the Qaidam (CD), the Tienshan (TS) and Tibet (TB). The kinematic model is mainly derived from the Global Positioning System (GPS) velocity data during the latest 10 years' observations, based on the method of the global plate model. The resulting Euler vectors predict that the movements of these microplates are consistent with the geophysical and geological observations of relative movements of the plates along their boundaries and that indicates it reasonable to regard these blocks as rigid ones.

Key words: Western China, Active block, Plate movement, GPS, Euler vectors
