摘　　要：在广西龙胜县平等金矿区开展了1∶1万土壤地球化学测量工作。结合矿区地层、构造、岩浆岩等地质特征,进行了土壤地球化学测量找矿工作研究。通过元素含量分析,得出矿区Au、Pb、Ag、As、Sb、Hg元素含量相对较高,其中Au的变异系数最大,说明Au参与了次生富集作用;通过元素组合分析,得出矿区As-Sb、Pb-Ag-Zn-Hg、Au三类元素组合,主成矿元素Au与其他元素的相关性都很低,反应金矿化的成矿物质来源比较复杂;通过单元素异常及综合异常的分析,圈定出了3个找矿重点靶区。On the basis of the geological features such as stratum,structure,magmatic rock,etc.in the mining area,the soil geochemistry survey of 10,000 scale is carried out in Pingdeng gold mining area in Longsheng County,Guangxi.According to the elemental content,it is found that the contents of such elements as Au,Pb,Ag,As,Sb,Hg are relatively higher than other elements in the mining area.The variation coefficient of Au is the largest,indicating that Au element participates in the secondary enrichment.Through element combination analysis,there are As-Sb,Pb-Ag-Zn-Hg,and Au three types of element combination in the mining area.The main metallogenic element,Au,has a low correlation with other elements.It is inferred that the source of gold-forming mineralization materials is relatively complex.Three key target areas for ore prospecting are identified by the analysis of single element anomaly and synthetical anomaly distribution.
