摘　　要：北沟掌勘查区位于华北克拉通北缘中段,区内地层出露简单,北西向断裂构造发育,化探异常明显,1∶50000水系沉积物测量与1∶10000土壤测量异常套合好,Ag、Pb、Zn、Au、Mo等元素异常重现性较好,异常浓集中心明显,峰值高,与区内的蚀变带相耦合,区内已圈定12条蚀变带与4条矿化体,化探异常、蚀变带与矿化体郡守北西向断裂构造控制,经研究认为,该区有较大找矿潜力。The Beigouzhang exploration area is located in the middle section of the northern margin of the North China craton.The strata in the area are exposed simply,the NW-trending fault structure is developed,and the geochemical anomaly is obvious.The 1∶50000 stream sediment survey and 1∶10000 soil survey anomaly are well matched.The anomaly recurrence of Ag,Pb,Zn,Au,Mo and other elements is good,the anomaly concentration center is obvious,the peak value is high,and it is coupled with the alteration zone in the area.12 alteration zones and 4 mineralization bodies have been delineated in the area,The geochemical anomaly,alteration zone and mineralized body are controlled by the NW-trending fault structure of Shou.According to the study,the area has great prospecting potential.
