西澳州CattleCreek地区铜镍硫化物矿床成矿潜力探讨 Introduction TheCattleCreekareainWesternAustraliaisknownforitspotentialforcopper-nickelsulfidedeposits.TheregionissituatedintheArcheanYilgarnCraton,whichhasalonghistoryofmineralization.TheaimofthispaperistoexplorethemineralizationpotentialandgeologicalcharacteristicsoftheCattleCreekarea. GeologicalSetting TheCattleCreekareaislocatedinthesouthernpartoftheYilgarnCraton,whichiscomposedofavarietyofrocktypes,includingmetasediments,granites,andgreenstones.Theareahasbeensubjectedtoseveralphasesofdeformation,includingfoldingandshearing,whichhaveledtotheformationofnumerousfaultsandfractures.Therocksintheareahaveundergoneextensivechemicalalterationduetohydrothermalfluidsandweathering. Depositionalhistory ThedepositionalhistoryoftheCattleCreekareaischaracterizedbyseveralstagesofsedimentationandvolcanicactivity.DuringtheearlystagesoftheArcheanperiod,theregionwascoveredbyshallowseas,whichdepositedsandstonesandshales.Subsequentvolcanicactivityresultedintheformationofbasalticandandesiticrocks.Later,magmaticintrusionsofgranitesanddioritesoccurredintheregion,leadingtotheformationofseveralmineralizedsystems. MineralizationPotential ThemineralizationpotentialoftheCattleCreekareaissignificant,withseveralcopper-nickelsulfidedepositsidentifiedintheregion.Thesedepositsareassociatedwithmaficandultramaficrocks,whichhaveundergoneextensivechemicalalterationduetohydrothermalfluids.Themineralizationisprimarilyhostedinsulfideores,includingpyrrhotite,chalcopyrite,andpentlandite.Thedepositsarecommonlyassociatedwithfaultzonesandshearzones,whichactasconduitsformineralizedfluids.
