A New View on the Global Redox-Cycle of Biosphere Carbon

The global carbon cycle model is presented as a natural self-regulating machine that provides renewable biomass synthesis during evolution. consists of two parts, geological and biosphere. Between the there an interaction. part controlled by movement lithosphere plates, which under guidance gravitational forces from celestial bodies acting on Earth. plates divided into phase relatively quick movement, occurring in tectonically active state Earth’s crust, named orogenic period, slow quiet geosynclinal period. In energy moving plates’ collisions sufficient to initiate sulfate reduction, proceeding subduction zone. This reaction where sedimentary organic matter oxidized. Resultant CO2 injected “atmosphere—hydrosphere” system Its concentration achieves maximal values, whereas oxygen drops minimum since it reacts with reduced sulfur forms evolve thermochemical reduction due binding metals, coming surface volcanic exhalations. Carbon dioxide initiates photosynthesis associated biosphere events. ceases, does not enter anymore, though proceeds regime pool depletion. Under such conditions, temperature Earth decreases, ending glaciations. successive depletion results regular sequence climatic changes ratio CO2/O2 key environmental parameter providing changes. They consistently vary hot anaerobic period glacial aerobic end provide biotic turnover. Especially abrupt accompany transition new cycle, resulting mass extinction organisms entry huge masses biogenic material sediment. provided conditions for formation rocks rich (“black shales”).
