Journal: Russian Geology and Geophysics

Publisher: Novosibirsk State University

Published: 01 June 2018

...–Wonoka negative carbon isotope excursion (Middle Ediacaran). Carbonates of the lower Nepa Regional Stage (Besyuryakh Formation) demonstrate positive δ 13 C values (up to 5‰) and minimum 87 Sr/ 86 Sr ratios of 0.70796–0.70832. The C and Sr isotope record of the Nepa Regional Stage provides its robust...
