Generation rule of geothermal resources in Fuzhou and analysis of potential geothermal anomaly areas

Based on systematic geological investigation in potential geothermal anomalous areas in Fuzhou, this paper first carried out comprehensively study of geothermal fields’ topographic characteristics, lithology, faults, crustal architecture and geophysics, depth of hot groundwater circulation, temperature of the reservoir and hydro-geochemical characteristics, etc. It can be concluded that the low-lying areas, such as basins and valleys where NE-and NEE-trending faults intersect and where the concentrations of F^-, SO^2-₄, SiO₂ and Sr are quite high in groundwater, are the potential prospective areas for geothermal resources. The knowledge can provide valuable information for seeking new potential geothermal anomaly areas in Fuzhou.
