【摘要】 以郯庐断裂带苏皖交界段落槽探编录分析和断错物质的微观变形特征分析为例,对比探讨断裂段晚第四纪以来的活动特征,结果表明,微观所揭示的断层新活动习性与探槽分析结果较为吻合,即郯庐断裂带苏皖交界地区段落,自晚更新世以来曾发生数次以斜向平移逆冲为主要方式的快速变形事件.但两者在表现形式上有所不同,微观变形形迹更丰富多样.研究结果一定程度弥补了常规断层活动习性分析局限.更多还原

【Abstract】 To take fault exploring trench charactre’s analysis in the junction segment of Tan-lu fault zone and microscopic deformation features analysis of the dislocated material for an example,conteast discussion on the fracture activities features of the fault segment since later Quaternary,results that,macro-micro revealed fault’s new activities habits and research slot analysis of results more match,that is in the junction segment of Tan-lu fault zone had happen number of times fast deformation events go for the main way to inclined to translation inverse. But their performance is different,microscopic deformation show more diverse.The results of the study must be made up limited extent for the regular analusis of fault activity habits.更多还原
