摘　　要：本文介绍了双频激电法配以放射性方法找金的机制,结合实例总结出数条规律,即石英脉型金矿化,一般表现为高视幅频率F_s和高视电阻率ρ_s特征;蚀变岩型金矿化,当硅化强烈时,除个别表现为高视电阻率外,一般表现为低ρ_s和高F_s特征;当破碎裂隙含水充泥或第四系覆盖较厚时,ρ_s和F_s均受影响而有所下降。This paper introduces the mechanism of prospecting for gold with the dual-frequency IP method and radioactive method. Several rules have been obtained to combine with examples, these are: to gold mineralisation of quartz vein type, generally it indicates the characteristics of higher resistivity,ρ_s and higher polarizability F_s; To gold mineralization of altered rock type, when silicification is strong, it indicates the characteristics of lower ρ_s and higher F_s except individually expressing as higher ρs; when the fracture zone is filled water or mud or the thick Quaternary overburden is developed, ρs, and F_s are all affeced and reducing
