郯庐断裂是我国东部纵贯南北的一组深大断裂。为了测定该断裂新活动的年代,我们根据前人提供的该断裂某些活断层露头与丁梦林等同志共同进行了调查与采样。样品采集 在江苏新沂嶂山闸东一公里新沂河北岸,可见到一条走向北10°东的地裂缝。裂缝面倾向北西,倾角约70°。在河南岸,也有同一裂缝延伸通过。该剖面由中更新世的黄色和浅黄绿色亚粘土夹密 The Tan-Lu fault is a group of deep faults that run through the north and south of eastern China. In order to determine the age of the new activity of the fault, we investigated and sampled together with Ding Menglin and other comrades based on the outcrops of some active faults of the fault provided by our predecessors. Samples collected in Jiangsu Xinyi Yushan gate one kilometer Xinyi Hebei north bank, you can see a 10 ° north to the north of the ground fissures. The fracture surface tends northwest, dip about 70 °. In Henan, there are also the same cracks extending through. The profile is clamped by mid-Pleistocene yellow and light yellowish green clay
