摘　　要：2009年开始安徽省地球物理地球化学勘查技术院在皖南地区开展了横船渡等四幅图的1∶5万水系沉积物地球化学测量工作,发现了石台县银坑地区Ag、Cu、Pb、W、Mo、Bi、As、Sb,综合异常区,并在异常区域进行了1∶1万土壤地球化学测量工作,对异常元素组合良好的青山异常和甘坑异常开展岩石剖面和槽探工作,发现了铜矿化体3条,获得了银坑地区铜多金属找矿线索。该地区位于石台—青阳金—银—铅—锌—钨—锰成矿区,具有较好的成矿地质背景,通过对以往地质、物化探资料的进一步研究,认为该地区为一较好的铜多金属找矿靶区。Beginning in 2009 the Institute of Geophysical and Geochemical Survey Technology of Anhui Province carfled out 1 ： 50000 stream sediment geochemical survey in the south Anhui area covering four map sheets as Hengchuandu, etc., found Ag, Cu, Pb, W, Mo, Bi, As and Sb composite anomalous elements zones in the Yinkeng area of Shitai County, and then performed 1：10000 soil geochemical survey in the anomalous zones, further did rock profile and trenching work in the Qingshan and Gankeng anomalies with good association of anomalous elements, and discovered 3 lines of copper mineralization bodies and obtained clues for prospecting copper polymetals in the Yinkeng area, which is located in the Shitai-Qingyang gold-silver-lead-zinc-tungsten-manganese metallogenic district, with good geological setting for mineralization. Further study of previous geological and geophysical data also supported that the area is a good target for copper polymetals.
