Abstract

Abstract

By calculating the fault throw index and growth index of the active faults in Langgu sag, Jizhong depression, the fault throw figures and fault growth index figures of this sag in each geological time were drawn out. Research showed that Daxing fault had different activities at different locations. The activity was weakened gradually from the southwest to the northeast as a whole. During the sedimentary period of Ek to Es₄, the three-level active faults were mainly located in the southeastern part of the sag, and were active weakly. During the sedimentary period of Es₃ to Es₂, the distribution of active faults was gradually extended to northeast from the southeastern part of the sag, with intense faults activity. The results suggested that the activity of active faults in Paleogene was mainly controlled by structural evolution background, and the activity of other active faults was also influenced by Daxing Fault.
