摘　　要：通过在广西那坡地区开展1∶5万水系沉积物测量,并以获得的地球化学数据为基础,分析研究了水系沉积物中元素含量分布、相关关系、组合特征,圈定了元素异常,划分出6个综合异常远景区;结合异常区域的地质背景、成矿地质条件等因素评价其找矿潜力,认为工作区Pb、Zn、Au、Sb、W矿找矿潜力较大,为下一步地质找矿工作指明方向。Through 1∶50000 stream sediment survey in Napo area of Guangxi province,it analysised the element content distribution,correlation,ombination feature,delined of element anomalies,divided 6 potential prospecting areas based on geochemical data;then it assessd prospecting potenrial combining geological background,metallogenic geological conditions,as well consided the study area has more prospecting potential about Pb,Zn,Au,Sb,W mine,which identified the next step direction of geological prospecting work.
