Facies-dependent δ13C variation and diagenetic overprinting at the onset of the Sturtian glaciation in North-East Greenland

Abstract:

Time-significant surfaces are used to construct a stratigraphic test of the intrabasinal reproducibility of a 16‰ Neoproterozoic carbon-isotope (δ 13 C) anomaly in the NE Greenland Caledonides. The δ 13 C excursion from +6‰ to -10‰ occurs in the carbonate-dominated Andrée Land Group and lies below glacial diamictites of the Tillite Group commonly correlated as Sturtian in age (~720 Ma) and has been widely interpreted to record a global isotopic event reflecting a perturbation in the carbon cy...
