摘　　要：激发极化法是一种寻找硫化物金属矿床的有效方法,被广泛应用于矿产勘查工作中.通过介绍时间域激发极化法在辽宁凤城矿产远景调查中的应用,进行激电中梯面积测量后,圈定5个激电异常,并解释和评价.对探槽揭露发现有Cu,Pb,Zn矿带的M4激电异常布置了4条激电测深剖面,对潜在的矿(化)体的埋深和形态进行了描述,对进一步深部找矿提出了建议.As one of the effective methods to search for sulfide metallic deposits,the induced polarization （IP） method is widely applied in mineral exploration.The paper discusses the application of time domain IP method in mineral prospective survey in Fengcheng County,Liaoning Province.With area measurements in IP intermediate gradient,five IP anomalies are delineated.Based on geological and geochemical survey,four IP sounding profiles are laid out in the M4 anomalous area of Cu,Pb and Zn belts revealed by trench.The burial depth and shape of potential mineralized body are described,which provide suggestions for further deep prospecting,
