摘要
Using the seismic network monitoring data at the southern end of the Taihang Mountains and the small earthquake P wave travel time data, this paper reconstructs the three-dimensional velocity structure model for the southern end of the Taihang Mountains fault zone by joint inversion of seismic source and velocity structure. The results show that: on the west of Taihang Mountains piedmont fault zone, there exists a NNE-trending fault. Horizontal distribution shows a zonal distribution of low velocity zone along the fault zone. The thickness of the sedimentary layer in Taihang Mountains uplift has reduced gradually from approximately 8 km to about 2 km, while under the force from the western side, the crust thickens gradually.
