Abstract: Exploration of concealed convective geothermal resources has always been a tricky issue in geothermal survey. In order to improve exploration precision of position selection in concealed convective geothermal resources, the authors in this research have taken Huating Lake scenic spot in Taihu County of Anhui Province as an example to determinate key areas, target areas and boring location through remote sensing interpretation, geothermal geological survey, CSAMT and hydrochemical analysis, based on the forming conditions and main features of regional geothermal fields. The groundwater with 22 ℃ and 780.4m³/d outflow(drawdown, S=20.62 m) was discovered, and its hydrochemical characteristics are similar to the geothermal fluid, with the consistent water-bearing structural location between actual aquifer and deduced aquifer by CSAMT. The exploration workflow for concealed convective geothermal resources exploration is summarized and the application effect of the exploration method is analyzed based on above research. The researchers in this paper conclude that water-bearing structure can be effectively identified by the CSAMT, and the effective way to determine geothermal resources is systematical hydrochemical analysis. Besides, it is essential to analyze and identify structure system of geothermal resources during exploration.
