摘　　要：本次调查工作共完成:地质调查点380个、1∶5万地质测量1 099.94 km2、地质物探综合剖面17条527.37 km、地质剖面(不同比例尺)202.17 km、地化剖面0.1 km、1∶5万水系沉积物测量280 km2、槽探1 847.61 m3、钻探1 000.67 m及1∶2.5万、1∶10万地形图数字化27幅。通过本次工作临江铜矿东北向控矿构造在玄武岩下部仍有延伸,在玄武岩盖层“天窗”发现错草顶子铜矿点,五人把铜矿点,其成矿地质背景与成矿条件均与临江铜矿相同。另通过地气测量圈定的异常进行钻孔验证,在玄武岩下部见有铜矿体1条及多条铜矿化、钼矿化蚀变带。In this survey, it has completed 380 geological survey points, 1 099.94 km~2 of 1∶50 000 geological survey, 527.37 km of 17 comprehensive geological and geophysical profiles, 202.17 km of geological profile(different scales), 0.1 km of geochemical profile, 280 km~2 of 1∶50 000 stream sediment survey, 1 847.61 m~3 of trenching, 1 000.67 m of drilling, and 27 digitized topographic maps of 1∶25 000 and 1∶100 000. Through this work, the northeast-trending ore-controlling structure of Linjiang copper mine still extends in the lower part of basalt. The Cuocaodingzi copper ore spot and Wurenba copper ore spot are found in the “skylight” of basalt cover. Their metallogenic geological background and metallogenic conditions are the same as those of Linjiang copper mine. In addition, the borehole verification was conducted through the anomaly delineated by the geological gas survey. There was a copper ore body and several copper mineralization and molybdenum mineralization alteration belts in the lower part of the basalt.
