摘　　要：普朗铜多金属矿是“三江”成矿带内超大型斑岩铜矿床,成矿地质条件优越,近年在矿区南部施工多个钻孔显示较好的金矿化信息,目前缺乏深入研究和系统总结。矿区南部开展了1/5000构造地球化学测量,异常元素以Au、Ag、As、Sb为主,多呈带状、片状重叠产出,各元素异常套合较好。圈定的YS1和YS2两个综合异常带均位于石英闪长玢岩与角岩的接触带附近,显示出较好的找矿前景。ThePulang copper polymetallic deposit is a super-large porphyry deposit located in the'Sanjiang'metallogenic belt.The metallogenic geological conditions are superior.In recent years,multiple boreholes constructed in the southern part of the mining area have shown good gold mineralization.However,there is a lack of in-depth research and systematic summary.In this work,1/5000 tectono-geochemical survey was carried out in the southern part of the mining area.The abnormal elements are mainly Au,Ag,As and Sb,which are mostly banded and flaky overlapping,and the anomaly of each element is well fitted.The two comprehensive anomaly zones of YS1 and YS2 delineated by are located near the contact zone between quartz diorite porphyrite and hornfels,showing a good prospecting prospect.
