Abstract 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.
