　　Changbai Mountain in China has been explored as a potential area for enriching thermal spring and cold spring waters.A study of the hydrogeochemical characteristics and reservoir temperatures of the nine thermal springs and fifteen cold springs were evaluated by hydrogeochemical analysis,statistical analysis and geothermometry analysis.The results showed that the concentrations of ions of thermal spring waters were commonly higher than those of the cold spring waters.HCO3- and Na+ were the most abundant anion and cation in the thermal spring waters,and the type is Na-HCO3.While the cold springs were enriched in Ca,Mg,HCO3 and SO4,and the types are Ca-Mg-HCO3-SO4,Ca-HCO3,Ca-Mg-Na-HCO3 and Ca-Mg-Na-SO4-HCO3.The temperatures of thermal spring waters ranged from 35 ℃ to 84 ℃.Anorthite,olivine,pyroxene and SiO2(a)were under-saturated for all thermal spring waters,and olivine,pyroxene,SiO2(a),dolomite and fluorite were under-saturated for all cold spring waters.
