Abstract Chishanhu area is located in Jurong City of Jiangsu Province. Jurong belongs to the southern Jiangsu region of Yangtze block and has poor hydrogeological conditions. In combination with gravity, electrical sounding and MT, geological and drilling data, the authors chose resistivity inversion profile of CSAMT and microtremor measurement to explore lithology and depth of the thermal reservoir and location of the fault. Based on geothermal and hydrogeological conditions, the authors confirmed the geothermal well site and then successfully revealed a hot spring with water output of 500 m3/day and temperature 55℃ through actual drilling.
