ThedensitiesofCO_2inclusionsinmineralsarecommonlyusedtodeterminethecrystallizingconditionsofthehostminerals.However,conventionalmicrothermometryisdifficulttoapplyforinclusionsofsmallsize(<5-10μm)orlowdensity.RamananalysisisanalternativemethodfordeterminingCO_2density,providedthattheCO_2density-Ramanshiftrelationisknown.ThisstudyaimstoestablishthisCO_2density-RamanshiftrelationbyusingCO_2inclusionssynthesizedinfusedsilicacapillaries.Byusingthisnewly-developedsynthetictechnique,weformedpureCO_2inclusions,andtheirdensitiesweredeterminedbymicrothermometry.TheRamananalysisshowedthattherelationbetweenCO_2density(Ding/cm3)andtheseparations(△incm~(-1))betweenthetwomainbands(i.e.Fermidiadbands)inCO_2Ramanspectracanberepresentedbyacubicequation:D(g/cm~3)=0.74203(-0.019⊿~3+5.90332⊿~2-610.79472⊿+21050.30165)-3.54278(r~2=0.99920).OurcalculatedDvalueforagiven⊿isbetweenthoseobtainedfromtwopreviously-reportedequations,whichwerederivedfromdifferentexperimentalmethods.AnexamplewasgiveninthisstudytodemonstratethatthedensitiesofnaturalCO_2inclusionsthatcouldnotbederivedfrommicrothermometrycouldbedeterminedbyusingourmethod.
