摘　　要：结合成矿地质条件,简要介绍了磁法、甚低频电磁法、瞬变电磁法、激电测深在金矿找矿工作中的不同特点和作用;给出了在豫西几个金矿区多金属成矿带上寻找隐伏金矿体的成功实例,说明在具备地球物理前提的条件下,用磁法、甚低频电磁(或瞬变电磁)法快速扫面测量可圈定找矿靶区。在找矿靶区做一定量对称四极激电测深工作,可预测矿体埋藏深度等;这是经济、快速地探测浅—深部隐伏、半隐伏盲矿体的有效方法,值得推广应用。In combination with geological conditions,this paper deals briefly with the different characteristics and roles of magnetic method,very low frequency method,transient electromagnetic method and IP sounding method in the ore-prospecting work.Some successful case studies of the prospecting for concealed ore bodies in some gold ore districts of western Henan are presented in this paper,which show that the rapid scanning survey by using magnetic method and very low frequency method（or VLF-EM method） can delineate ore-prospecting target areas,and the symmetric quadrupole IP sounding method can be used to predict buried depth of the ore body.These methods are effective means for economic and rapid detection of shallow-deep concealed and semi-concealed blind ore bodies and hence deserve widespread application.
