SOME APPLIED ASPECTS OF THERMOBAROGEOCHEMISTRY OF MOLYBDENUM-TUNGSTEN AND GOLD ORE FORMATIONS

Abstract

The applied direction of thermobarogeochemistry is important for the implementation of variousscale predictive and metallogenic works and for solving various geological problems that require solutions at different stages of the geological exploration process. The theoretical basis of thermobarogeochemical forecasting, prospecting and mineralization assessment is the stability of the regime of physicochemical conditions for the formation of productive mineral parageneses. They are formed in a rather narrow range of changes in the thermobarogeochemical characteristics of the ore-forming environment specific in chemical composition and aggregatedensity state, which is manifested in the phase typomorphism of the corresponding families of fluid inclusions practically regardless of the geological conditions and metallogenic specialization of the ore regions. This circumstance testifies to the distinct convergence of physicochemical conditions and thermobarogeochemical indicators of the development of genetically related ore-forming processes of molybdenum-tungsten, gold-ore and other formations. An equally important prerequisite for the implementation of the problems of applied thermobarogeochemistry is the variability of diagnostics and spatial extrapolation of gradients and trends of these parameters (thermobarogeochemical zonation) with the determination of the spatial position of zones that are physicochemically favorable for the development of molybdenum-tungsten, gold or other mineralization, as well as the upper and lower ore physicochemical levels of their wedging, taking into account the structural and facies conditions of ore localization.
