LEFT AND RIGHT STRIKE SLIP FAULT SERIES

15 strike-slip fault was a large basement strike-slip fault. The dynamic characteristics are analysed based on the structural style of the superimposed development model and the nature and activity intensity of strike-slip faults in different periods. Based on highly precise 3D seismic section, coherent attribute slice and time slice, the geometric and kinematic characteristics of the fault are analyzed. This paper fills in the blank of geometry and kinematics research on the strike-slip fault zone in this area. There are almost no previous studies on strike-slip faults in the eastern Sichuan Basin.

LEFT AND RIGHT STRIKE SLIP FAULT SERIES

It is found that there are a series of NW-SE base-trending strike-slip faults in this area besides NE-SW strike-blocking structures. The eastern Sichuan Basin has undergone multiple stages of tectonic evolution and shows complex structural characteristics.
