Abstract：GeothealwaterinteYangjawangeotheralwellXinpuarea，Zunyiorthnzouasuedatereseachjectto discussthe genesisofgeothermal waterbasedonthehydrochemicalcompositionandhydrogen-oxygenisotopecharacteristicsof geothermal water.The hydrochemical type of geothermal wateris -Ca·Mg type，thebeneficial elementsaremainly SrandF.The origin of geothermal water isatmospheric precipitationrecharge in the Dalou Mountainarea，withits recharging elevations of 1 3 5 0 m ，and the temperature of the recharge areas is approximately .The estimated thermal storage temperature is and the depth of hot Water circulation is 1 0 7 0～1 1 3 7 m .The percentage of cold water mixing in geothermal water was calculated to be 82 % by silicon-enthalpy modeling.
