摘　　要：矿区处于冈底斯-念青唐古拉褶皱系伯舒拉岭-高黎贡山褶皱带的古永-盏西褶皱束内,通过对矿区1:2.5万土壤地球化学数据进行地球化学参数统计,揭示了区内元素组合特征,并圈定了单元素异常和综合异常。在矿区圈定8处有远景的综合异常区内,通过1:1万地质填图及不同程度的工程揭露,发现锡、金、银矿化体。研究表明,土壤地球化学测量在此区域行之有效,为同类型地球化学景观区内找矿提供了借鉴价值。The mining area is located in the ancient Yong-calyx fold belt of the Gangdise-Xunqing Tanggula-koraaling-Gao Li Gong mountain fold belt.The geochemical parameters of the soil geochemical data of 1:2.5 ten thousand soil in the mining area are counted,and the combination characteristics of the elements in the area are revealed,and the single element anomalies and the comprehensive anomalies are delineated.Delineating 8 prospective abnormal areas in the mining area,we discovered tin,gold and silver mineralizing bodies by 1:1 geological mapping and various engineering exposing.The study shows that the soil geochemical survey is effective in this area,which provides a reference for prospecting in the same type of geochemical landscape area.
