Geodynamics and geochemistry processes of density convection in East European evaporite paleobasin
Abstract
The article is devoted to the fundamental problem of modern fluid geodynamics and fluid geochemistry - clarifying the role of the gravitational factor in the formation of the East European kydrostratisfera sedimentary basin. The features of the Paleozoic depositional, the mechanism and lithologic-hydrogeochemical consequences of the halogenesis processes and uterine brines density convection of Lower Permian evaporite basin into underlying terrigen calcareous Paleozoic and Proterozoic environment. It was found that the exchange-adsorption and exchange-absorption interaction between brine and clastic rocks was been few involved in metamorphism chloride brines. The lithological-thermodynamic studies and balance calculations in the “brine-carbonate rock” system showed that the main role in the formation of multicomponent calcium chloride brines in the sedimentary cover basin, belongs to the processes of metasomatic dolomitization of limestone.
