Catagenesis of organic matter of sedimentary sequence in Omra-Soyva district

The results of coal-petrographic, geochemical and pyrolysis research of Devonian sediments within Omra-Soyva district are presented in the paper. Paleotemperature gradients were calculated, and models of catagenetic heating of Paleozoic sediments were constructed. They showed that in different parts coeval strata underwent the main oil generation stage not simultaneously, which can be explained by the different abyssal zonation of catagenesis.
