摘　　要：在内蒙古某铅锌矿勘查中,采用地质、化探、激电法、EH-4电磁测深等综合方法,取得了较好的地质找矿效果。建立了物化探"两高一低二边"(即高极化率、铅锌多金属元素质量分数高,低电阻率积磁场梯级带、视电阻率梯级带)的综合找矿模型,结合地质因素,对在该地区找寻构造破碎蚀变岩型的铅锌多金属硫化物矿体(矿化体),具有明显的指导作用。In the article in prospecting a Pb-Zn ore in Neimenggu,use synthetic methods of geology,geochemistry reconnaissance and induced polarization and EH-4 etc.,acquired better result of geology and looking for ores.The building of modle of look for mineral deposit of geophysics and geochemistry reconnaissance of ＂two high,one low and two gradient zone＂ that is high in polarization rate and the content of Pb-Zn and polymetals,low in resistance rate,magnetic gradient zone and gradient zone of apparent resistivity rate,synthesized the geological factor,it has abvious guiding function to look for ore body of Pb-Zn and metal sulphide of break altered rock type.
