摘　　要：潭口金矿床位于华夏板块之雩山隆起的西段,为快速缩小找矿靶区并评价矿区金矿资源状况,对该区开展1∶10 000沟系次生晕土壤地球化学测量工作,圈定以Au元素为主的综合异常2处,经地表异常查证及1∶2 000地质填图工作,并采用槽探工程揭露圈定2条含金矿化地质体。在地表面积性工作基础上对该区龙王迳区段选择钻探、坑探工程进行系统揭露和控制,取得了良好的找矿效果,此表明该方法在土壤层发育区能够有效快速地缩小圈定找矿靶区及准确指明找矿方向。The Tankou gold deposit is located in the western section of the Yushan uplift of the Cathaysian Plate.In order to quickly narrow down the prospecting target area and evaluate the gold resource of the mining area,the 1∶10000 valley system secondary halo soil geochemical survey was carried out,and 2 comprehensive anomalies dominated by Au elements were circled.Through the investigation of the surface anomalies,1∶2000 geological mapping,and the exposure of trench exploration,two gold-bearing mineralized bodies was circled.On the basis of the surface survey,the Longwangrun section of the deposit was selected for systematic exposure and control by drilling and pitting projects,and it showed a very promising prospecting potential.This research indicates that this method is effective in narrowing down the target area and accurately indicating the direction of prospecting in the soil layer development area.
