摘要
The East Kunlun fault zones are located in the northern margin of the Bayanhar block. The authors carried out a number of field geological investigation, typical micro-topography DGPS measurement and sample dating. The results show that earthquake activities of the East Kunlun fault zones extend to the north bound of the Zoige Basin. This part has been named Luocha segment, which belonged to the Tazang fault. The phenomena show that the Tazang fault was the causative fault of the earthquake and raptured in Holocene. The fault has been controlled by compressive shear recently and shows horizontal movement with slight thrust components, similar to other segments of the East Kunlun fault zones. The results supports the “mainland escape” model.
