通过地震剖面、可控源异常体解译、野外露头剖面勘察以及施工钻孔和连孔剖面等资料,首次详细证实了大路—姚桥断裂具新构造运动特征,根据邻区测年结果及中晚更新世沉积的下蜀组老黄土,推断出断层的活动时间为第四纪中更新世早期和中更新世以前。新构造运动致使中更新世以来断层两侧沉积了完全不同的岩相特征,形成了2套不同的沉积体系。新构造运动的发现对镇江市的规划和建设以及地质灾害的预防具有重要的指导作用,对苏锡常地裂缝的研究具有一定的指导意义。
According to the seismic profiles, interpretation of controllable source anomalous bodies, the investigation of outcrop profile in the outcrop and the data of construction borehole and even-hole profile, the characteristics of neotectonic movement of Dalu-Yaoqiao fault are confirmed for the first time. Based on the dating results of neighboring areas and Late Pleistocene sediments of the old Shu loess, infer the active time of the fault in the Quaternary Early Middle Pleistocene and before the Middle Pleistocene. Neotectonic movement resulted in the deposition of completely different lithofacies on both sides of the fault since the middle Pleistocene, forming two different depositional systems. The discovery of neotectonic movement plays an important guiding role in the planning and construction of Zhenjiang City and the prevention of geological disasters. It has some guiding significance for the study of the Chang-Shang-Chang fracture.
