Abstract:In order to investigate the occurrences, properties and shallow tectonic features of the east-Qingshui river fault, we complete high resolution shallow seismic profiles crossing the fault and obtain shallow seismic reflection stacked profiles which have higher signal-noise ratio. According to these results, and combined with geological data, we analyze and discuss the shallow structures features of the fault. The results show that east-Qingshui river fault is a near SN trending and E dipping reverse fault. In the shallow position the east-Qingshui river, the fault shows “Y” structure which consists of 2-3 fault. The fault disrupts 10~20 m Quaternary strata in the shallow part, therefore it buried active faults in the Quaternary period.
