The periodicity of geotectonic stages and coal generation
The study of the process of coal sequence generation and coalified organic matter accumulation in sediments in relation to large time cycles is described. Derivation of cycles from geotectonic stages (of some 220 million years) is made. The periodicity of geotectonic stages and their hierarchy and phases of development make it possible to consider major cycles of coal genesis. The duration of the main coal genesis period might have been some 40 million years, starting with the end of the third quarter of the geotectonic stage and coming to an end at about the middle of the fourth quarter.
