甘肃某金矿地质地球化学特征及成因分析 Title:GeologicalandGeochemicalCharacteristicsandGenesisAnalysisofaGoldMineinGansu,China Abstract: ThegeologicalandgeochemicalcharacteristicsofagoldmineinGansuProvince,China,areanalyzedinthisstudy.Theresearchaimstoprovideinsightsintothegeologicalformationandgenesismodelofthegolddepositsintheregion.Basedonfieldinvestigations,drillingdata,andlaboratoryanalysis,itisfoundthatthegoldmineralizationinthemineiscloselyassociatedwiththeregionaltectonicevolutionandthemagmaticactivities.Moreover,thegeochemicaldataindicatesthatthegolddepositsareofanepithermaltypeandareenrichedinbasemetalssuchascopper,lead,andzinc.Theresultssuggestthatthegoldmineralizationinthisregionisprimarilyrelatedtothehydrothermalprocesses,whichcouldbepotentiallyusedforexplorationanddevelopmentofsimilargolddepositsinthefuture. 1.Introduction GolddepositsarewidelydistributedinGansuProvince,andthestudyareaisoneofthekeygoldminingregions.Understandingthegeologicalandgeochemicalcharacteristicsofthegolddepositsiscrucialforsuccessfulexplorationandexploitationofmineralresources.ThisstudyaimstoprovideacomprehensiveanalysisofthegeologicalandgeochemicalfeaturesofagoldmineinGansu,China,andexploreitsformationmechanism. 2.GeologicalSetting Theresearchareaislocatedinatectonicallyactiveregion,withmultiplestagesoftectonicevolution.Thegeologicalunitsconsistofvolcanicrocks,sedimentaryrocks,andintrusiverocks,whichhaveundergonecomplexdeformationandmetamorphism.Thegoldmineralizationoccursmainlyinthevolcanicrocks,whichareassociatedwithstructuraldeformationsandfaultactivities. 3.FieldInvestigationsandDrillingData Detailedfieldinvestigationswerecarriedouttostudythedistribution,morphology,andstructuralcharacteristicsofthegolddeposits.Thedrillingdataprovidedvaluableinformationontheverticalandlateralextensionofthemineralizationzones.Theresultsindicatethatthegolddepositsaremainlyconcentratedinthefracturezonesandfaultshearzones. 4.GeochemicalAnalysis Geochemicalanalysisofthegold-bearingrocksandoreswasconductedusingvario
