摘要

显微激光拉曼光谱仪作为一种新型的微区分析仪器,其高精度、方便、快捷、无损的特点,为地学研究中新技术、新方法的应用提供了最先进的手段。通过研究不同物质拉曼光谱的变化特征,可以帮助确定流体包裹体中流体的成分和盐度,同时利用激光诱导荧光还可以获得显微组分的荧光变化特性。因此,激光拉曼光谱分析可以为流体性质、沉积环境及成藏期次研究提供重要依据。

Abstract

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.
