Abstract: | The article is dedicated to multidisciplinary studies of organic matter (OM) in Eocene deposits. In the Ciscaucasia region, the mean content of organic carbon in the Kumian deposits is high. A decrease in quality is partly related to the approaching of the displacement source. In the investigated regions of Ciscaucasia and Crimea, hydrogen sulfide contamination of the water column in Eocene basins did not exist. Eocene carbon deposits are characterized by increased and high OM oil source potential. A sharp increase in primary biological production is likely to be related to endogenous processes. |
