Abstract:The shallow seismic reflection method is used in the geophysical exploration of the Danjiang fault in the southern Qinling mountains tectonic belt. Through data processing and analysis, high resolution shallow seismic profiles with characteristics of geometric distribution, breakpoint burying depth and fault properties are obtained. In this paper, the results of seismic profiles and drilling data of part lines are verified by comparison. The results show that the shallow seismic reflection is effective for the hidden detection in this area, and this method can provide reference for the detection of buried active faults.
