Lithological and geochemical characterization of Silurian deposits in the Talbeysky block of Chernyshev ridge

The article presents the results of lithological and geochemical research of Silurian deposits in the Talbeysky block of Chernyshev ridge, which are one of the important objects to exploration for hydrocarbon deposits. Based on the structure and lithological composition of the deposits three series were defined in wells section: sulphate-carbonate, carbonate and argillo-carbonate. The Lower Silurian sulphate-carbonate and carbonate series contain mostly poor source rocks (TOC
