Geophysical processes and biosphere: article

Аnnotation: The paper features the concept of biosphere impact on the Earth’s evolution which is confirmed by the relevant calculations. According to this concept the shell structure was formed during the prebiosphere period. In this period the global convection occurred as the tectonics of small plates. The absence of the continents in this period excludes the involvement of water in oxidation of igneous rocks. During the biosphere period the photosynthetic organisms began to supply free oxygen and organic matters (OM) in their environment using the solar energy. Oxygen is involved in the geochemical processes of ore formation, nitrogen and oxygen of the atmosphere formation and in generation of granites from magma effusives. For the first time there distinguished the global systems of the granite generation of the continental crust and hydrocarbons (HC) which are formed at subduction-collision absorption of the oceanic crust. On the way to transition into the Benioff zone granites are melted out from the products of halmyrolysis enriched in oxygen and the thermal OM metamorphism yields solid allotropic carbon compounds, oil, combustible and other gases and is accompanied by the release of energy resulted from OM decomposition. This is one of the ways of the conversion of the biosphere solar energy into endodynamic processes of the Earth’s evolution. The average annual precipitation of the primary organic matter in the ocean is 785.5 Mt and 1.7 km
