Claypool continued: Extending the isotopic record of sedimentary sulfate
Abstract The Proterozoic Eon spans Earth's middle age during which many important
transitions occurred. These transitions include the oxygenation of the atmosphere …

Snowball Earth climate dynamics and Cryogenian geology-geobiology
Geological evidence indicates that grounded ice sheets reached sea level at all latitudes

U-Pb and Re-Os geochronology tracks stratigraphic condensation in the Sturtian snowball Earth aftermath
The snowball Earth hypothesis predicts a strong hysteresis resulting in discrete multi-million-
year glaciations followed by globally synchronous deglaciation. Here we present new U-Pb …
