Significance of Fluid Inclusion Studies of Barytes Deposits of Rajgarh Area, District Alwar (Rajasthan) India |
Fluid inclusion study in barytes of Rajgarh deposits wascarried out to determine the role of temperature, pressure and composition ofthe fluid medium from which minerals were formed – depends upon the correctidentification of fluids trapped from the original medium during growth ofcrystals, as distinct from those introduced at some later stage in the historyof the mineral. It has been proved that the results of fluid inclusion studiesare so consistent and reasonable that most of the scientists accepted them assuch. The density, salinity rate of movement and composition of the solutioncan be determined by the fluid inclusion study to understand the origin ofdeposits. More elaborated studies can yield data on isotopic and chemicalnature of hydrothermal solutions. Under certain circumstances (when mineralprecipitates from boiling solution), the true temperature of precipitation anddepth below the pale horizon can be calculated. The fluid inclusion studieshave been used in fields of economic Geology, Mineral Exploration,Sedimentology, Stratigraphy, Geothermometry, Geochemistry, etc. Fluidinclusions are probably best known as a Geothermometry specially in the studyof ore deposits, indicating the chemical composition of hydrothermal solutions.
