Progress towards an improved Precambrian seawater 87Sr/86Sr curve
The secular trend of seawater strontium isotope ratio (87 Sr/86 Sr) reflects changes in the
relative contributions of continental versus mantle reservoirs to ocean composition, and …

Past climates inform our future
BACKGROUND Anthropogenic emissions are rapidly altering Earth's climate, pushing it
toward a warmer state for which there is no historical precedent. Although no perfect analog …

Snowball Earth climate dynamics and Cryogenian geology-geobiology
Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

A Cryogenian chronology: Two long-lasting synchronous Neoproterozoic glaciations
The snowball Earth hypothesis predicts globally synchronous glaciations that persisted on a
multimillion year time scale. Geochronological tests of this hypothesis have been limited by …

Calibrating the terminations of Cryogenian global glaciations
Abstract Cryogenian Sturtian and Marinoan glacial and associated strata record the most
severe paleoclimatic events in Earth history and are the main test ground of the snowball …

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 …

Cyclostratigraphic constraints on the duration of the Datangpo Formation and the onset age of the Nantuo (Marinoan) glaciation in South China
Constructing an accurate timeline is critical for reconstructing the Earth systems through
critical transitions in climate, geochemistry, and life. Existing dates constrain synchronous …
