Tying the C-isotope excursions of the Neoproterozoic successions of Tandilia System: Phantom glaciations?

The Neoproterozoic era (1000–539 Ma) encompasses drastic global changes, including extreme climatic events and transformative evolutionary transitions. Snowball Earth hypothesis (cf. Snowball vs Slushball Earth hypotheses) suggests that during Cryogenian the Earth was “completely” ice-covered Sturtian (~720-710 Ma) and Marinoan (635 Ma) events. In Ediacaran times, Gaskiers (582 Ma) followed by Shuram (~570 Ma) events were related to δ13C excursions recorded globally and commonly associated with prominent sedimentological, geobiological and geochemical changes.
