BULK AND LOCAL TECHNIQUES OF ANALYSIS OF VOLATILE COMPONENTS IN FLUIDINCLUSIONS

Destructive and nondestructive techniques of analysis of gas phase of fluid inclusions in minerals have been considered. Thermometry, Raman spectroscopy, and gas chromatography have been compared taking quartz, topaz, and cassiterite as examples. It has been shown that the degree of agreement of dta taken by these techniques depends mainly on the i ndividual features of a sample. The pure the mineral, as well as the m ore inclusions it has and the more uniform the inclusions are the clos er the data of these different techniques. We conclude that to choose a technique one should consider the features of both sample, fluid inc lusions in there and the task. Sometimes it can be only destructive or nondestructive techniques otherwise - any of them of a combination.
