摘　　要：依据浅层地震勘探结果、钻孔和重力资料,进一步厘定了磁县-大名断裂东段的空间展布、断层上断点埋深。研究认为该断裂具有分段活动特征,最新活动时代为中—晚更新世,并推测出磁县-大名断裂东延至范县古城镇南一带。The Cixian-Daming fault is one of the important faults in North China earthquake area.It is the seismogenic structure of the 1830 Cixian M7.5 earthquake.Based on the results of shallow seismic exploration,borehole and gravity data,this paper further determines the spatial distribution of the eastern section of Cixian-Daming fault and the buried depth of breakpoints on the fault.It is considered that the fault has the characteristics of segmented activity,and the latest activity age is the middle late Pleistocene.It is speculated that Cixian-Daming fault extends eastward to the south of Gucheng Town,Fanxian county.
