摘　　要：马蹄沟—王家台地区处于南秦岭铅-锌-银-金-汞-铜成矿带。通过开展1∶2.5万水系沉积物测量,采用元素变异系数、相关性分析、聚类分析等方法,在马蹄沟—王家台地区圈定了7处Au-Ag-As-Sb组合异常、7处Cu-Pb-Zn组合异常及3处找矿靶区,经工程验证发现并圈定了矿化蚀变带及矿体,表明该地区具有较好的找矿前景。Matigou-Wangjiatai area is located on the Pb-Zn-Ag-Au-Hg-Cu metallogenic belt,South Qinling.Based on the 1∶25000 stream sediment survey,element variation coefficient,relevance analysis,and cluster analy-sis methods are used,delineating 7 Au-Ag-As-Sb element composite anomalies,7 Cu-Pb-Zn element composite anomalies,and 3 prospecting targets.Verified by engineering practices,mineralized altered belts and ore bodies are discovered and delineated,indicating good prospecting potential in the area.
