摘    要:本文根据青岛市活断层探测与地震危险性评价项目初查阶段第四纪地层分析、遥感影像解译、地球化学探测、地质地貌调查与探槽开挖、浅层地震勘探与钻孔探测、地质年代测定等获得的丰富的第一手资料,对青岛沧口断裂的地质构造特征和第四纪活动性进行了详细分析与综合研究,结果表明:沧口断裂经历多期构造变动,是本区的重要断裂之一,它由多支断层组成,控制了中生代的火山活动、盆地沉积和岩浆侵入以及晚第四纪的盆地沉积、山体隆升和水系发育;第四纪以来,沧口断裂的主要活动发生于中更新世晚期至晚更新世早期,表现出中高角度向南东倾的逆冲活动特点,错断了上更新统底面1—6m,而最新活动时代为晚更新世中期,以走滑活动为主,垂直错距0.2—1.1m。

关 键 词:断裂  地质构造  第四纪活动性  青岛  浅层地震勘探  槽探  钻探

Abstract:Making use of abundant field survey/exploration data about Quaternary strata,geomorphology and satellite images,geological surveying/trenching results,seismic reflection profiling,drilling results and geological dating,this paper discusses the geological features and Quaternary activities of Cangkou Fault in Qingdao,China. The research results make known that Cangkou Fault has undergone polygenetic tectonic variance,which is one of the key faults in the area.Cangkou Fault is consisted of several sub-faults,and controls the volcanic activity, sedimentation in the basin and magmatic intrusion in Mesozoic Era as well as the sedimentation in basin,uplifting and development of drainage system in the Late Quaternary Period.Since Quaternary the main activity of Cangkou Fault took place from the late Middle Pleistocene to early Late Pleistocene,which display the middie-high angular inclination to Southeast and thrust active features.This fracture staggered the bottom surface of upper Pleistocene Series for 1-6 m.The latest active time is the middle Late Pleistocene with the main feature of strike-slip and 0.2 -1.1 m vertical displacement distance.
Keywords:Fault  Geological structure  Quaternary tectonic activity  Qingdao  Shallow seismic investigation  Trenching  Drilling
