Abstract
Applying modern analytical methods, we investigated organic matter from the Lower-Middle Cambrian rocks of the Kuonamka Formation in the eastern Siberian Platform. We divided the rocks into groups and subgroups according to the content of organic carbon and studied the contents and distribution of saturated biomarker hydrocarbons in them. The concentration of organic matter is shown to be correlated with the distribution of relic hydrocarbons. We also estimated the sedimentation conditions, petroleum potential, and catagenesis of black shales.
