pdf Characterization of Upper Wenlock and Lower Ludlow strata in the Silurian reference section of the Chernov Uplift (Timan-Pechora petroleum province)
The features of the Upper Wenlock and Lower Ludlow boundary strata in the Silurian reference section located in the central part of the Chernov Uplift in the Arctic zone of the European Northeast of Russia are characterized. Significant changes in sedimentation conditions, in the composition of different groups of organic remains, and in the behavior of carbon and oxygen isotopes, are revealed, which coincide with global biotic and isotopic events indicating a major ecosystem reorganization at the Wenlock - Ludlow boundary. The biostratigraphic correlation of the studied different facies Silurian strata in the Padimeityvis River basin with the coeval strata on the western slope of the Subpolar Urals, on the Chernyshev Uplift and on Dolgiy Island allows considering the stratigraphic completeness of the Wenlock and Ludlow strata in the Silurian section on the Chernov Uplift as unique.

Keywords: Wenlock, Ludlow, Silurian, isotopes of carbon and oxygen, biostratigraphic correlation, Chernow Uplift, Timan-Pechora petroleum province.
