通过对北西向断层在新生代凸起造成的下切谷、断裂的活动年代和强度等方面的研究,对济阳坳陷中、新生代断层之间的切割关系进行了分析。结果表明,济阳坳陷早期发育的5条北西向断层被后期发育的北东(东)向断层所切割,孔店期-沙四期是主要的切割时期。断层切割期前,济阳坳陷受北西向断层控制;断层切割期,北西向断层和北东向断层共同控制盆地的发育;断层切割期后,北西向断层基本停止活动,北东向断层控制了盆地的发育。
Based on the study of the NW-trending fault under the Cenozoic uplift, age and intensity of the down-cut valleys and faults, the relationship of the cutting between Mesozoic and Cenozoic faults in the Jiyang depression was analyzed. The results show that the five NW faults developed early in the Jiyang Depression are cut by the NE (East) fault developed in the late stage, and Kongdian - Sha 4 is the main cutting period. Before the fault cutting period, the Jiyang Depression is controlled by the NW fault. During the fault cutting period, the NW and NE faults control the development of the basin. After the fault cutting, the NW strike basically stops and the NE strike fault control The development of the basin.
