Early-Middle Frasnian (Late Devonian) carbon isotope Event in the Timan-Pechora Basin (Chernyshev Swell, Pymvashor River section, North Cis-Urals, Russia)

Biostratigraphically constrained carbonate (δ13Ccarb) and organic carbon (δ13Corg) variations in the Early-Middle Frasnian boundary interval in the Pymvashor River section (Timan-Pechora Basin, Cis-Urals, in the far north of European Russia) were considered. The studied interval of section is repres...
