Newly discovered paleosols in the Gaskiers Formation of Newfoundland provide a new perspective on its paleoenvironment, and are evidence that it was not a deep submarine tillite, nor the first highly oxidized deep-sea floor, nor a cap carbonate from extreme geochemical perturbation of the global...
At present, three Neoproterozoic glacial events have been described, namely the Sturtian (∼760–700 Ma), Marinoan (recently determined as 635 Ma, Hoffmann et al., 2004), and Gaskiers glacial event (Newfoundland, Canada). An Ediacaran biota 565 ± 3 Ma in age occurs above this last ...

Macrofossils of the inferred protistゞrade organism Palaeopascichnus linearis occur stratigraphically beneath glacial diamictites of the ~580 Ma, Gaskiers〆quivalent, Trinity 'facies' of the Rocky Harbour Formation on the Bonavista Peninsula of Newfoundland, Canada. These fossils significantly preヾ...
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 ...
DEGLACIAL STRATIGRAPHY AND PALEOMAGNETISM OF THE GASKIERS-DROOK TRANSITION, AVALON PENINSULA, NEWFOUNDLANDWe report four fine-scale lithostratigraphies supporting paleomagnetic sampling of Gaskiers-Drook transition in southern Avalon, and we suggest lateral continuity of cap carbonate deposition, ranging from...
