摘　　要：大水金矿属于秦祁昆造山带,东昆仑—南秦岭褶皱系,西秦岭南亚带,共圈出96个矿体,组成3个较大的矿体群,属于中低温热液金矿床。本文通过物探推测法、化探预测法、Pb同位素预测法、坑内浅钻控制法4种研究大水金矿深部成矿预测靶区,研究结果表明在大水金矿西区深部及中区的南测找矿潜力巨大。Located at Qinling-Qilian-Kunlun orogenic belt,eastern Kunlun-South Qinling fold system and the southern subzone of the Western Qinling Mountains is Dashui gold deposit where about 96 ore bodies has been outlined,composing three large ore cluster.The deposit is a middle-low hydrothermal gold deposit.The comprehensive exploration methods including geophysical,geochemical and Pb isotopes for prediction and shallow drilling in pit for verification are employed to predict ore body in deep.The research shows that there are huge potentials for deep ore-prospecting in west and middle of Dashui gold deposit.
