英格蘭西南部花崗巖中液包裹體的巖相學(xué)研究及其在找礦工作中的潛在價值A(chǔ)PetrologicalStudyofFluidInclusionsinGranitefromSouthwestEnglandandtheirPotentialValueinMineralExploration

Introduction:

GraniteisacommonlyoccurringrockinSouthwestEngland,characterizedbyitscoarse-grainedtextureanduniquemineralcomposition.Thestudyoffluidinclusionsinthisrockhasbeenfoundtohavegreatimportanceinexplorationforminerals.Inthispaper,weaimtoinvestigatethepetrologicalpropertiesoffluidinclusionsingranitefromSouthwestEngland,andtheirpotentialvalueinmineralexploration.

Methodology:

ThesamplesofgranitewerecollectedfromseverallocationsinSouthwestEngland.Thinsectionswerepreparedfromtherocksamplesandobservedunderanopticalmicroscopetoidentifythemineralcomposition.Fluidinclusionsinthesampleswerethenanalyzedusingaheating-freezingmicroscopetodeterminethevolumeandcompositionofthefluidscontainedwithin.

Results:

ThegranitesamplesinSouthwestEnglandtypicallyconsistofquartz,feldspar,mica,andbiotite.Fluidinclusionsinthegranitewereobservedtobedominantlyaqueous,withsomesamplescontainingsmallamountsofcarbondioxide.Thefluidinclusionswerefoundtobeofvarioussizes,rangingfromafewmicrometerstoseveralhundredsofmicrometers.Thevolumeoffluidscontainedintheinclusionsrangedfromlessthan5%toover30%,withthemajorityofinclusionscontaininglessthan10%fluid.

Discussion:

ThepresenceoffluidinclusionsingranitefromSouthwestEnglandisofgreatimportanceinmineralexploration.Thevolumeandcompositionoffluidscontainedwithintheinclusionscanprovideimportantinformationaboutthegeologicalprocessesthathaveoccurredintherock.Theaqueousnatureofinclusionsinthegranitesuggeststhatgroundwaterhasplayedasignificantroleintheformationofthisrock.Thepresenceofcarbondioxideinsomeoftheinclusionsmayindicatethepresenceofmineraldepositssuchasgoldandcopper.
