摘　　要：激电法是探查铅锌矿体行之有效的物探方法之一。广西佛子冲铅锌矿危机矿山接替资源找矿中,在矿区地质特征及地球物理特征的基础上,开展了激电中梯扫面和激电测深,圈定了多处物探电法异常;结合以往地质、化探、钻探成果资料,区分出矿致异常和非矿致异常;结合矿区地质、地球化学特征,建立了该矿区地质-地球物理-地球化学找矿模型,为下一步的地质找矿工作和钻探工程的布置提供了较为可靠的物探依据。通过钻探工程验证,其中7个钻孔均揭露到厚5~8 m的多层铅锌矿体,取得了比较良好的找矿效果,物探激电异常显示了佛子冲矿区及其外围具有巨大的找矿潜力。IP method is an effective method to explore for the Pb-Zn orebody.This paper takes the application of IP method in the sabstitue mineral resources prospecting of crisis mines in Fozichong Pb-Zn deposit in Guangxi as an example,and discusses how to carry out IP mid-ladder scanning and IP sounding survey under certain metallogenic condition and geophysical feature,providing a reliable geophysical basis for the next geological work and the arrangement of drilling holes.Through the drilling verification,seven drillin holes have encountered multi-layer lead and zinc orebodies with the thicknesses ranging from 5 to 8 meters.It has achieved for a good prospecting effect.IP anomalies have showed that there is still a huge prospecting potential in the Fozichong mining area and its periphery.
