Keywords:geothermalresources;Xichenarea;geothermalsource;geochemicalanalysis;mineralizatioInrecentyears,thedevelopmentandutilizationofgeothermalresourceshasreceivedincreasingattentionduetoitsabundance,cleanliness,andsustainability.TheXichenarea,locatedinthenorthwesternpartofChina,isrichingeothermalresources.Ithasbeenconfirmedthatthegeothermalwaterinthisareaismainlyhotspringwater,whichiswidelydistributed.

ThegeochemicalanalysisshowsthatthegeothermalwaterintheXichenareaischaracterizedbyhighmineralization,hightemperature,andhighcarbondioxidecontent.ThemainmineralcomponentsareNa+,Ca2+,Mg2+andHCO3-.ThepHvalueofthegeothermalwaterisgenerallyaroundneutral,whichisconsistentwiththecharacteristicsofdeepgeothermalwater.ThestableisotopeanalysisoftheoxygenandhydrogeninthewaterindicatesthatthegeothermalwaterintheXichenareaismainlyderivedfrommeteoricwater.

Furthermore,thestudyalsorevealsthatthegeothermalsourceintheXichenareaismainlyfromdeepcrustalhydrothermalsolutionsandatmosphericprecipitation.Thedeepgeothermalwaterhasbeenheatedbytheearth'scrustandisenrichedwithmineralsubstancesduringcirculation.Thehightemperatureandpressureenvironmentatdepthmakesthegeothermalwatercontainavarietyofusefulminerals,suchaslithium,boron,andfluorine.
