Abstract: Abstract Constructing an accurate timeline is critical for reconstructing the Earth systems through critical transitions in climate, geochemistry, and life. Existing dates constrain synchronous initiation (ca. 717 Ma) and termination (ca. 660 Ma) of the… read more here.

Abstract: Abstract The continuous existence of the Marinoan Ice Age, a late Cryogenian panglaciation (Snowball Earth), is challenged by the occurrences of widespread glacial marine and nonglacial deposits consisting of stratified diamictite, laminated siltstone and claystone,… read more here.

DOI: 10.1130/g49134.1
Abstract: Global Neoproterozoic glaciations are related to extreme environmental changes and the reprise of iron formation in the rock record. However, the lack of narrow age constraints on Cryogenian successions bearing iron-formation deposits prevents correlation and… read more here.
