摘要
With the increasing exploration depth of concealed metal deposits, the single geophysical methods are unable to meet the present exploration needs in depth and precision. To solve this problem, this paper proposes a combined method of CSAMT (controlled-source audio frequency magentotelluric) and SIP (spectral induced polarization) technology, and applied it to the survey of concealed metal deposits in the Luanchuan mountainous area, Henan Province. The results show that this method can explore to larger depths, discriminate anomalies well and has higher resolution to deep objects.
