应用显微激光拉曼光谱分析单个流体包裹体同位素

单个流体包裹体同位素是研究特定成岩成矿（藏）阶段古流体成因和来源最有效的方法之一，在矿床、油气、地质流体和大地构造演化动力学等多个领域具有十分重要的用途。但是，目前还没有成熟的分析单个流体包裹体同位素的方法。文中在对目前国内外流体包裹体分析技术总结分析基础上，认为激光拉曼光谱是一项可以分析单个流体包裹体同位素的最有效方法，国外在该领域已经开展了许多创新性的研究工作，并取得了一些重要进展。对激光拉曼光谱分析单个流体包裹体同位素的原理和可行性进行了分析论证，提出通过对已知比值的同位素标准物质拉曼光谱测试和研究，在确定稳定同位素分子的拉曼参数和实验条件等基础上，可以建立起单个流体包裹体稳定同位素激光拉曼测试方法，从而改变目前只能依靠分析群体包裹体同位素来示踪古流体成因和来源的局限性和不确定性。

Analysis of isotope of individual fluid inclusion by means of laser Raman spectroscopy

Stable isotope of individual fluid inclusion is one of the most effective methods for the study of formation and fluid sources of specific petrogenesis and metallogenesis of mineral deposits.It is widely used in geology of ore deposits,oil/gas geology and geodynamics of geo-fluids and tectonic evolution.However,there is not any technology or method for the analysis of stable isotopes in single fluid inclusions both at home and abroad.Based on summarizing the analytical techniques of fluid inclusions,this paper considers that the laser Raman spectroscopy is the most effective method for stable isotope analysis of single fluid inclusions.Indeed as one of the effective methods,laser Raman spectroscopy has been researched and has been made important progress.Based on the study of principles and feasibility of the method of laser Raman spectroscopy,it is proposed that laser Raman testing method for stable isotopes of single fluid inclusions could be established by Raman spectroscopy testing and researching of the standard materials with known isotopic ratios.In this way Raman parameters and experimental conditions of stable isotopes in single fluid inclusions could be determined.It will help to free from restriction and uncertainty in tracing the origins and sources of paleo-fluids caused by the analysis on group fluid inclusions.
