MODERN ISSUES OF EVAPORITE FORMATION IN THE GEOLOGICAL HISTORY OF THE EARTH

Abstract

The relevance of the work. The geochemical specificity of the underground hydrosphere is extremely varied in composition brines and salt waters, which are characteristic of platform-type sedimentary basins with halogen formations. Therefore, elucidation of the origin, formation and distribution patterns of salt-bearing rocks is one of the fundamental problems of modern theoretical geology of oil and gas. The purpose of this work is to analyze the features of the formation of evaporites in the geological history of the Earth. The high importance of scientific and applied problems of "salt" geology and the wide interest in this problem are traditionally determined by the needs for various halurgic raw materials, as well as their close ties with the interests of many disciplines (hydrogeochemistry, studies of mineral deposits, oil and gas geology, etc.). The work reveals the possibility of using data on modern halogenesis to decipher the conditions and patterns of ancient salt accumulation in different geological periods, ranging from relatively young to the most ancient; in identifying the relationship and relationship of continental and marine halogenesis in different geological epochs; Conclusions : The regularities of the distribution and formation of salt-bearing rocks have been revealed, and the possibility of their use as sources of hydromineral raw materials has been determined.
