Radiometric constraints on mid-Ediacaran Period glaciation (Gaskiers) in Newfoundland narrowed the known temporal gap between widespread ice ages and the evolution of complex metazoans to several million years. To further evaluate this claim we studied an Ediacaran glacial diamictite at the base of ...
Discontinuous outcrops of diamictites and siltstones are found above post-Marinoan carbonates from the Araras Formation and represent the record of a second glaciation in the northern Paraguay belt, Brazil. This new stratigraphic unit, named the Serra Azul Formation, varies in thickness between 250...
These paleosols are evidence of a humid temperate climate and marked marine regression accompanying Gaskiers Glaciation of the early Ediacaran (580 Ma). Geochemical weathering trends in the paleosols, especially phosphorus depletion, are characteristic of biologically active soils. Ediacaran microbial ...

The 20-30 m of siltstone and shale presumably recording the deglacial aftermath of Gaskiers glaciation appears as anomalous, in the Avalonian succession, as the diamictite sequence itself.RAUB, Timothy D
