西秦岭北缘断裂带西端晚第四纪活动特征及其西延问题

Abstract

Abstract: The northern margin of Western Qinling fault zone (NWQF) is one of the main left-lateral strike slip active faults in northeastern margin of Tibetan Plateau. Through field seismic and geological investigations, we opined that the west segment of this fault remain actively strong. Significant Holocene activity characteristics are found in Qielonggou. Trenches show that at least two Holocene paleoseismic events happened in west segment of NWQF, which shows that fault activities of NWQF still exist in the west of Tufang village, extend westward from Tufang village continually and finally terminate at the Ganjia basin.

Key words: Western Qinling fault zone, Fault activity, Paleoseismic events, Ganjia basin
