临漳-大名断裂活动特征
摘要:    临漳-大名断裂位于覆盖层较厚的平原地区,处于隐伏状态,为获得断裂的浅部构造特征以及活动特征,在断裂上采用高分辨浅层地震探测方法,获得了两条高质量叠加时间剖面图以及深度剖面图,这些图像清晰地显示了断裂的浅部构造以及活动特征。探测结果表明,临漳-大名断裂活动时代具有分段性,临漳段断裂上断点埋深120m,最新活动时代为中更新世早期;大名段断裂上断点埋深105m,最新活动时代为晚更新世中期。

Active Characteristics of the Linzhang-Daming Fault
Abstract:      The Linzhang-Daming fault is blind fault and buried in the plain area which is covered by the thick cap rock. Two high quality time sections and the depth profiles were obtained with high resolution shallow seismic detection method for analysis of the characteristics of shallow structure and activity. The results show the shallow structure and activity of fault characteristic information. The fault is of segmentation, in which the breakpoint of Linzhang segment is at the depth of more than 120m with early stage of middle Pleistocene and the breakpoint of Daming segment is at the depth of more than 105m with middle period of Late Pleistocene.
Keywords:  Linzhang-Daming fault  High resolution shallow seismic detection  Activity characteristics of fault
