Abstract：he Pangusi-Xixiang fault tendency reversed near the Dagao village. The western part is south tendency and east part is north tendency. In order to determine the inversion genesis in the Pangusi-Xinxiang fault tendency reverse regional, we set 3 shallow seismic survey lines across the fault. Based on the high-resolution seismic data acquisition and high-precision data processing technology, the clear underground structure and tectonic imaging is obtained of the fault tendency reverse regional. The results show that there is a hidden uplift in the north edge of the Wuzhi uplift, and the development of the hidden uplift makes the western part of the Pangusi-Xinxiang fault disappeared between L1 and L2. At the same time, the Wuzhi fault became the boundary fault of the Jiyuan sag. From west to east, the hidden uplift scale increases gradually. The east part of the Pangusi-Xinxiang fault and the Pingling fault began to develop at the margin of the hidden uplift. With the hidden uplift increasing, the activity of Pangusi-Xinxiang fault and the Pingling fault gradually increases. It is suggested that the hidden uplift is the main cause of the tendency inverse of the Pangusi-Xinxiang fault. The results provide a reliable basis for the characteristics and activity evaluation of Pangusi-Xinxiang fault.
