Abstract:On the basis of ananlyzing the hydro-geochemical characteristic of geothermal water, the formation and evolution of chemical compositions in the geothermal have been studied in this paper. By the analysis of hydro-geochemistry, isotope ananlysis and paleohydro-geological conditions; the origin of geothermal water in Heze uplift has been discussed, the geothermal water being infiltration metamorphic water from rainfall concluded.
