郯庐断裂是纵贯我国东部的规模巨大的断裂带。它对我国东部的地质发展史、矿产分布、地震活动都有重要的控制作用。它的主体在山东、安徽一带,研究较详。但向北经勃海入辽宁后伸向何处?则众说纷云。根据我们近几年来的野外地质观察结果和结合物探、卫片、地震等方面资料分析,对于郯庐断裂的北延问题,提出粗浅看法,与同志们共同讨论。 The Tanlu fault is a large-scale fault zone that runs through the eastern part of our country. It plays an important role in controlling the geological history, mineral distribution and seismicity in eastern China. Its main body is in Shandong, Anhui area, the research is more detailed. But to the North by the Bohai into Liaoning after the stretch? According to our field geological observation in recent years and the combination of geophysical, satellite, seismic and other aspects of data analysis, for the northern extension of the Tan-Lu fault, put forward a superficial view, and comrades to discuss.
