摘　　要：富宁水合口金矿是滇东南微细粒浸染型金矿成矿带的一部分。基于在研究区开展的1∶1万土壤地球化学测量工作,分析了Au、Hg、Sb、As四个元素的含量、分布特征,圈出了异常,并结合地层、构造、岩性等地质特征对土壤地球化学异常进行了评价,从而圈定了6个找矿靶区。通过对3号靶区工程验证找到一个矿体,为水合口金矿其他地区的找矿前景提供了一个有效的依据。The Shuihekou gold deposit in Funing of Yunnan Province is a part of the Southeast Yunnan micro-fine-disseminated gold metallogenic belt. Soil geochemistry is a simple and effective method in search for micro-fine-disseminated gold deposits. Based on the1∶ 10 000 soil geochemical survey in the study area,the authors analyzed the content and distribution characteristics of the four elements of Au,Hg,Sb,As and delineated the anomaly. The anomaly was evaluated in combiantion with the geological features of layer,structure,lithology and the prospecting indicators of Southeast Yunnan micro-fine-disseminated gold metallogenic belt,thus delineating six prospecting target areas. An orebody was found through engineering verification of No. 3 prospecting target,which provides effective evidence for prospecting potential of the other areas in The Shuihekou gold deposit.
