RESEARCH ON LATE TECTONIC DEFORMATION EVOLVEMENT OF HUAIYUAN-LIUPANSHAN ARC FAULT AND ITS SURROUNDING AREA
海原-六盘山弧型断裂及其附近最新构造变形演化分析

By using three-dimension nonlinear dynamic finite method and GPS velocity fields in two time periods,the late tectonic deformation features of Haiyuan-Liupanshan arc fault and its Surrounding Area were studied.The following results are obtained.1) Haiyuan-Liupanshan fault is of left lateral slip in whole but they are different in the two sections that the left lateral slip rate of Haiyuan fault is 2-5.5 mm/a and Liupanshan fault about 1.0 mm/a.2) At present,the junction segment of Haiyuan fault with Liupans...
