Hypotheses that reflect the leading role of geologic change in the formation of the chemical composition of sedimentation basins during the Phanerozoic are proposed. The high salinity of the waters of the Paleozoic basins of the Northern hemisphere is explained by the concentration of salts during the periods of global glaciation. The shallow seas and negative temperatures in most of the world led to the fact that most of the water was withdrawn into the ice, and the remaining water (cry-opeg) was buried in precipitation. High salinity brines were the basis for large-scale Paleozoic halogenesis during the transition to a warm arid climate and this situation can be explained by the huge 67 thickness of many salt - bearing strata of the Paleozoic. Another situation arose in continental crystal massifs that never sank below sea level. At the end of the Proterozoic and early Paleozoic the African continent was located in the southern polar zone and at this time, powerful glaciers formed on its territory. In the late Paleozoic, glaciers began to melt, filling the cavities of crystalline rocks and adja - cent sedimentary basins with fresh water. The transgression of the Paleozoic seas did not affect the highly elevated crystalline massifs where fresh water was preserved.
