By conducting a comprehensive analysis of two shallow seismic profiles, VSP-measured P-wave velocity data, and one drilling joint geological profile from the Shenqiu depression in the southern north China basin, this study investigates the geometric characteristics and discernible upper fault depths of a series of negative flower-like structures in the shallow part of the strike-slip fault zone. The results indicate that the fault displaces the Quaternary strata upwards, with the discernible upper fault depth on the shallow seismic exploration profile being approximately 60 meters, and the discernible upper fault depth on the drilling joint geological profile ranging from 38.6 to 40.1 meters, suggesting that the fault displaces the middle Pleistocene strata. The exploration findings reveal that the fault is a set of left-lateral strike-slip faults arranged in a NWW direction, resembling a line of geese. This indicates that the southern north China basin has experienced NW-directed strike-slip shearing during the Quaternary, suggesting that the NW-directed tectonic system, controlled by the Qinling orogeny, has remained active since the Quaternary. This has significant implications for analyzing the evolution of the basins in the eastern plains of the north China block.
