Global Carbon Cycle and Organic Matter Accumulation in the Earth Crust

Global Carbon Cycle and Organic Matter Accumulation in the Earth Crust

The natural process of organic carbon accumulation in sediments is considered in the light of recently suggested model of global redox carbon cycle. It is inferred that in geologic time the process was uneven and some periods were favorable for the increased burial organic carbon rate. Organic carbon accumulation occurred in parallel with oxygen growth in the atmosphere. According to the model, the accumulation process is a cyclic one.
