摘要
通过野外地质地貌调查结合无人机航拍测量、地质雷达勘探及浅层地震勘探综合分析认为,金山凸起东缘断裂整体呈NE向展布,走向40°,北起忻口村一带,向SW经金山铺村西、前淤泥村西延伸至部落村以北,进而向SWS转折进入盆地区。经探槽开挖和年龄测试,该断裂段最新断错晚更新世早期地层。
By means of the field geological and geomorphological investigation combined with UAV aerial photography survey,geological radar exploration and shallow seismic exploration,we comprehensively reckon that the eastern margin fault of Jinshan uplift extends with the strike of 40°in a whole,starting from the northern Xinkou village,extending to the southwest through the western Jinshanpu village and western Qianyuni village,and turning to the SWS and into the basin area around northern Buluo village.Through trenching and chronology tests,we think the fault latestly misplaced the early Late Pleistocene strata.
