The Mall Bay Formation (Ediacaran) and the Protracted Onset of the Gaskiers Glaciation in Newfoundland, Canada
The Gaskiers glaciation (580 Ma) immediately preceded the appearance of the Earth’s first large, complex, soft-bodied, fossils of the Ediacara biota. The Gaskiers glaciation is generally regarded as being short-lived and confined to the stratigraphic extent of the Gaskiers Formation in eastern …

Sedimentology of the Squantum ‘Tillite’, Boston Basin, USA: Modern Analogues and Implications for the Paleoclimate during the Gaskiers Glaciation (c. 580 Ma)
The Gaskiers glaciation (c. 580 Ma) has been classically traced along the Neoproterozoic Avalonian-Cadomian Terranes, which are now found scattered around the North Atlantic Ocean. Around 625 Ma these terranes were composed of volcanoes and arc-type basins. ‘Till-like’ diamictite horizons …

Geochronological constraints on the Trinity diamictite in Newfoundland : Implications for Ediacaran glaciation
… terrane in Newfoundland includes the Ediacaran Gaskiers Formation, which has been associated with a Snowball glaciation event. The complicated regional stratigraphy and lack of precise geochronological constraints has made it difficult to determine the spatial and temporal extent of the Gaskiers …

The Neoproterozoic São Francisco Basin, central Brazil: tectonic evolution, paleoclimate, and mineral systems
… of a complete Wilson Cycle, three Neoproterozoic glaciations, and global changes in the biogeochemical cycling of nutrient elements. The basal Macaúbas Group (ca. 950-650 Ma), composed of rift-related sediments, accumulated during breakup of the supercontinent Rodinia. Deposition was punctuated by …
