LASER RAMAN MICROSCOPE AND ITS APPLICATION IN GEOLOGY

Laser Raman microscope is a new microanalysis device.With characteristics of high accuracy,convenience,high speed and no damage,it has provided the most advanced way for applications of new techniques in geology.Studies of Raman spectra characteristics of different materials help to determine fluid composition and salinity in fluid inclusions.Fluorescence variance of maceral may also be obtained by laser-induced fluorescence.Laser Raman microscopy can provide important evidences for fluid cha-racteristics,sedimentary environment and accumulation stage research.
