[Development of Raman spectroscopy study of fluid inclusions]

In the present paper, the exploration process of the laser Raman analysis of fluid inclusions was reviewed and summarized. The authors tried to outlook the future research work on laser Raman analysis of fluid inclusions at low and room temperature. Research work at low temperatures: (1) Common multiple salt systems in the fluid inclusions; (2) Trying qualitative and quantitative analysis of ingredients in natural fluid inclusions; (3) Microthermometry considered first melting temperature as the eutectic temperature, and this view was suspected, so further research is needed; (4) chloride hydrate structure is inconclusive at low temperatures. Research work at room temperatures: (1) how Fe3+, Zn2+, Cu2+ and other ions being considered as the main metal ions of mineralization combine with Cl- and H2O are how to combine; (2) The reason for different concentrations of NaCl, CaCl2, MgCl2, CuCl2, ZnCl2, FeCl3 solution resulting in the shift of Raman OH stretching region (2 800-3 800 cm(-1)).
