摘要: 程各庄断裂是马坊-夏垫断裂带北段的一条东分支断裂,根据其断层泥的显微结构、石英碎屑SEM特征、热释光年龄综合分析,结果表明,该断裂不同区段的最新活动都是以粘滑为主,但各个区段不同地质时期其活动方式和强度不同。Abstract: Chenggezhuang fault is an east-branching fault of Mafang-Xiadian fault belt. A ccomprehensive study, such as microstructure of gouges, observation of SEM quartz fragment and TL dating of the fault gouges, gives the result that the last movement mode is stick slip mainly in different segment and the movement mode and intensity are different in each segment during different geological period.
