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.
Taking the analysis of trenching records and microscopic deformation characteristics of fault-broken matter in the Tan-Lu fault belt at the junction of Jiangsu-Anhui as an example, the characteristics of the activity since the late Quaternary in the fault zone are compared and discussed. The results show that the microscopic- The analysis results of the trenches are in good agreement with the results of the rapid deforming events with diagonal translational thrusting as the main mode since the Late Pleistocene in the Tan-Lu fault zone and the boundary between Jiangsu and Anhui Provinces. However, Different, the deformation of the micro-more rich and varied.Research results to some extent make up for the limitations of routine tomographic activity analysis.
