摘　　要：基于激电测深和音频大地电磁测深(EH4)方法,对镇雄三山地区1条物探剖面测量分析,有效确定了空间电性和结构特征。判识了断裂2条(F_(5)、F_(51)),其中断裂F_(5)为控矿和导矿断裂。圈定了3个极化异常体(Ⅵ-1~Ⅵ1-3)及1处极化体(JHT1),并推断1处找矿有利部位,与断裂构造及层间构造有关。Based on induced polarization sounding and audio-frequency magnetotelluric sounding(E)H4 methods,a geophysical profile in the Sanshan area,Zhenxiong was analyzed,effectively determiningthe spatial electrical and structural characteristics.Two faults(F_(5) and F_(51))were identified,with F_(5) being the ore-controlling and ore-conducting fault.Three polarization anomalies(Ⅵ-1~Ⅵ1-3)and one polarized body(JHT1)were delineated,and a favorable prospecting area related to fault and interlayer structures was inferred.
