As Shenxian area is extensively covered by Cenozoic strata of rather great thickness, the prospecting for geothermal resources should find out the characteristics of thermal reservoir bed, cover bed and faulted structure. In this area, the CSAMT has a good transverse capability of distinguishing faulted structures, and the direct current electric sounding can yield fairly good result in distinguishing Cenozoic strata. Based on collecting relevant geological, seismic and logging data, the authors made geological integrated inference, with the direct current sounding semi-quantitative interpretation result as the constraint condition of the CSAMT quantitative interpretation. As a result, the buried depth and distribution of the deep concealed strata, thermal reservoir beds and faulted structures were basically detected, with good survey result obtained. It is held that the integrated application of two geophysical methods can yield results with high quality and high effectiveness in the early-stage exploration of geothermal resources.
