摘　　要：拉曼光谱在矿物包裹体成分研究中的应用近年来已有一些报导,而在国内则刚刚开始。通过矿物包裹体成分的分析可以获得成矿溶液的化学组成及有关的物理化学参数,这是矿床研究的宝贵资料。但是,矿物包裹体极其细小,一般只有几微米到几十微米。This paper introduces the general theory and method on analysis the composition of fluid inclusions with MOLE raman microprobe.At present,the destructive analytic method is bing used in the ana lysis of the composition of fluid inclusions.But this method can’t distinguish orignal and seconoary fluid inclusion and the solution of host minerals affects analytic results.The analysis of fluid inclusion with MOLE raman microprobe is non-destructive and point analytic method.The analytic results are satisfactory.Seven fluid inclusions have been analysed by the MOLE raman microprobe.One of them is the fluid inclusion in quartz from Danzhai mercujy deposit.The compsition of gaseous phase are CO_(2)42%,N_(2)37%CH421%.The compsi-tion of liquid phase is mainly water,the salinity 8 wt%.The doughter minerals in the fluid inclusions also have been determined to be calcit.The sample is fluorite of mineralization period in No 335 uranium deposit,Gua.ng-Dong province.The fluid inclusions in fluorit from No 681 uranium deposit,Zhe-Jiang province contain CO_(2),H_(2)S.The article also introduces Dhamelincourt’s work on study of fluid inclusions with MOLE raman microprobe.
