Geochemical and geophysical investigations were carried out to obtain more evidence of the potential of geothermal resources in Chunxiao Town (China). Hydrochemical data indicate the possible existence of mixing process between deep geothermal water and shallow groundwater. Analysis with SiO2 geothermometer shows that the geothermal reservoir temperature was estimated around 40–60 °C. In addition, combination investigations with CSAMT, radioactive radon, and soil thermal-released mercury detection reveal the specific location of the conduction fractures for thermal water circulation. Furthermore, the drilling work shows the deep thermal water temperature of >55 °C and the thermal water yield of 300 m3/d. All these results could provide important guidance for the scientific exploration and effective utilization of geothermal resources in coastal area. View Full-Text
