本文利用低温原位拉曼技术,对 CaCl_2-H_2O 体系和 MgCl_2-H_2O 体系人工合成流体包裹体进行了研究。结果表明:对于盐浓度不同的溶液而言,可采用不同的冷冻方式有效采集低温拉曼光谱;通过系统采集不同温度下的拉曼光谱,可以直接准确地测定包裹体中流体的成分和低温相变过程。人工合成包裹体原位低温拉曼光谱的研究,为将该技术应用于天然包裹体分研究奠定了理论基础,可以预见,该技术必将在流体包裹体研究领域发挥其它方法不可替代的重要作用。 In this paper, artificially synthesized fluid inclusions in CaCl 2 -H 2 O system and MgCl 2 -H 2 O system were studied by using cryogenic in situ Raman spectroscopy. The results show that for different salt concentration solutions, different freezing methods can be used to collect low temperature Raman spectra efficiently. By systematically collecting Raman spectra at different temperatures, the composition of the fluid in the inclusion and the low temperature phase can be directly and accurately determined Change process. In situ cryogenic Raman spectroscopy of synthetic inclusions has laid the theoretical foundation for the application of this technology in the study of natural inclusion. It is forecasted that this technique will play an irreplaceable important role in the research of fluid inclusions .
