    Abstract:

    In this paper, based on the filling active faults in geologic map with large scale in recent years,the authors present the basic activity characteristics of the fault zone at northern edge of western Qinling Mt. since late Quaternary period, and study the spatial distribution, geometry and kinematics characteristics, slip rate of fault,paleoearthquake and seismic recurrence period. The results show that the active way of the fault zone changes from compression to left-later-al slip since Quaternary period, with a horizontal slip rate 2.1-2.8mm/ year and a vertical slip rate of 0.4-0.7mm/year. The recurrence period of earthquake is about 5000 years in the fault zone.
