Abstract:

Abstract:  Starting from the successful application of low temperature Raman spectroscopy in studying some geologically interesting hydrates by Dubessy,the insitu cryogenic Raman spectroscopic technique has been used in the study of saltwater system fluid inclusions both synthetically and naturally produced and got great achievement in identification of different dissolved salts,and in the study of fluid phase equilibrium and salinityIt is verified that this technique is an important supplement to the traditional routine microthermometric study of fluid inclusionsThe insitu cryogenic Raman spectroscopic study is becoming a new hot spot in the fluid inclusion research fieldIt will have a broad application in the geofluid studies.
