Abstract: Based on the genesis of geothermal resources and field investigation in Jinzhou City, this study discusses the geological, hydrochemical and thermal reservoir characteristics of two different types of geothermal fields in the area, and evaluates their resource potential. The results show that the convective type is controlled by fault structures, all located at the outer margins of Mesozoic fault basins, mainly with structural fracture and karst thermal reservoirs, lithologically composed of cataclastic dolomite and dolomitic limestone; while the conductive type is controlled by mantle plume formed within the Cenozoic basins, dominated by porous medium thermal reservoir with mudstone and sandstone. The contents of fluorine, metaboric acid and metasilicic acid in geothermal water are slightly high. The total geothermal resource potential in Jinzhou City is estimated at 10.156×10¹⁵ kJ, with the extraction coefficient of 0.01-0.43, indicating tremendous potential for development and utilization of geothermal resources.
