国内外在流体包裹体激光拉曼光谱研究方面取得了大量的成果。本文回顾了流体包裹体激光拉曼光谱分析技术的发展历史,介绍了流体包裹体激光拉曼光谱技术定性和定量分析的原理和方法,指出了该技术存在的问题及未来研究方向。流体包裹体激光拉曼光谱分析主要受到样品、荧光、同位素、光化学反应、水溶性物质信号弱、气相水及水合物、子矿物等因素的影响。由于用来进行定量分析的拉曼散射截面参数明显受到压力影响,加上峰面积计算不规范化使得目前的流体包裹体激光拉曼光谱分析结果可靠性有待于重新审视。未来流体包裹体拉曼光谱分析技术应当在完善不同标准体系和标准物质光谱数据的基础上,针对不同类型包裹体采用采取不同条件,分析结果将在准确定性的基础上从相对定量向绝对定量发展。
With the development of new technology, laser Raman microospeetroscopy of fluid inclusions has been rapidly renovated in last decades. Information extracted from fluid inclusions has been widely used to interpret diverse geological processes. In this paper, writers review the history of research on Raman spectroscopy of fluid inclusions, introduce the theory and method of Raman spectroscopy of fluid inclusions, mainly discuss the problems and point out the future trends of this technique. The data of fluid inclusions analyzed by Raman spectroscopy are affected by samples, fluorescence, isotopes, photochemistry reaction, weak signal of water-solubility matter, water vapour and hydrates, and daughter minerals. Because the Raman scattering section of molecular changes with the pressure and the computation of area of Raman peak is not standardization, we must carefully treat the data from fluid inclusions by Raman spectroscopy. The future trends of laser Raman spectroscopy of fluid inclusions should be based on establishment the spectroscopy data of standard system and minerals, different type fluid inclusions should be analyzed under respective conditions, and the results will be developed from comparative content to absolute content ground on exact qualitative analysis.
