GRANITE FORMATION IN THE EARTH'S LITHOSPHERE BY THE EXAMPLE OF THE KAAKHEM MAGMATIC AREA (EASTERH TUVA)
The link of lithogenesis with granitogenesis is gradually substantiated. The role of atmosphere and hydrosphere is pointed out in the maximum efficiency of exogenous processes that caused the differentiation of the basaltic crust and the formation of the sedimentary crust. The origin of water and oxygen on the Earth is explained. The role of the eutectic is described in the formation of like- composition granite melt and as consequence, the formation of an intergranular eutectoid granite melt that further the continuous process of granite formation under the certain thermodynamic and geodynamic conditions.
Keywords: lithogenesis, granitization, melt, fluids, thermodynamic conditions, eutectic.
