摘　　要：镇雄祝家厂位于彝良—镇雄铅锌矿矿集区内。本文先利用土壤地球化学和中梯激电面积测量工作,圈出Pb、Zn元素两个异常(SH01、SH02),圈定1个极化异常体(JHL01),再利用音频大地电磁探测深部地质构造特征,查清了由地表至深部依次为薄中低层—高阻层—中低阻层电性特征,推断断裂(F_(5))为导矿构造和次级隐伏断裂(F_(51))为容矿构造,结合已知钻孔(ZK0202)资料,最终圈定1处成矿有利部位(S1)。Zhenxiong Zhujiachang is located in the Yiliang-Zhenxiong lead-zinc mining area.First of all,the soil geochemistry and the measurement of the middle-ladder IP area are used to delineate two anomalies of Pb and Zn elements(SH01、SH02),and one anomalous polarization anomaly body(JHL01)is delineated.Secondly,the audio magnetotelluric sounding is used to detect the characteristics of deep geological structure,and the electrical characteristics of the thin,middle and low layer,high resistivity layer and middle and low resistivity layer from the surface to the deep are identified.It is inferred that the fault(F_(5))is the ore conducting structure and the secondary hidden fault(F_(51))is the ore bearing structure,Based on the known borehole(ZK0202)data,a favorable location for mineralization(S1)is finally delineated。
