摘要
NW-trending faults are important basin-controlled fault in the Jiyang Depression,which generated earlier and have an crucially impact on post-construction. In this paper,based on the detailed interpretation of 3D seismic data of Zhuangxi Buried Hill in the Jiyang Depression,a new NW-trending fault was identified and named for ancient Zhuangxi Fault. This fault reconstruction of processes and styles,as well as the influence on the formation of the Zhuangxi Buried Hill,were analyzed. The results show that the ancient Zhuangxi Fault experienced thrust movement during Indosinian Period,negative inversion in the middle stage of Yanshanian,positive inversion in the late Yanshanian,again negative inversion in the Himalayan,eventually ancient Zhuangxi Fault was divided into five independent faults. Ancient Zhuangxi Fault had three kinds of remolding styles : direct inversion,inversion by strain hardening zone and cutting off by strike-slip fault. The long time activities of Ancient Zhuangxi Fault controlled the formation of NW-trending Zhuangxi Buried Hill and en-echelon NS-trending hills internally.
