摘　　要：放牛沟矿床中的矿物、岩石及矿石含汞量的差异说明汞的次生地球化学异常来自矿体,特别是PbZn矿体。壤中气汞(Hg°)、土壤吸附汞(△Hg)及全汞(THg)异常套合出现是PbZn矿体的可靠标志。全汞异常能反映浅部矿体;吸附汞和壤中气汞异常不但反映浅部矿体,还能指示盲矿体及含矿断裂。根据汞的地球化学异常特征的研究,结合地质、土壤和岩石地球化学勘查结果,提出了两处找矿有希望地段。The difference of mercury contents of minerals, rocks and ores indica tes that the geochemical anomaly of mercury comes from ore body in the Fangniugou deposit. The appearance of anomaly assemblage with gaseous mercury (Hg°), absorbed mercury (△Hg) and total mercury (THg) is available mark of the Pb.Zn ore body.The total mercury anomaly can indicate shallow ore bodies; absorbed m ercury and gaseous mercury anomaly not only indicate shallow ore bodies but also belind orebodies and ore-bearing fractures. Based upon the characteristics of geochemical anomaly of mercury and combined with the results of petro-geochemical and soil survey, two prospectives are proposed.
