GREAT OXYGENATION EVENT (GOE)
shortly after the extreme glaciations during the late Neoproterozoic (Hoffman et al., 1998) and was nearly synchronous with the rapid evolutionary pulse that coincides with the Ediacaran and Cambrian radiations. Final assembly of Gondwanaland and a circumGondwanaland mountain chain is thought to have provided nutrients to the oceanic realm and also resulted in a large 87Sr/86Sr spike due to the erosion of the mountains (Squire et al., 2006). Therefore, links between the assembly of the Gondwanaland supercontinent and biological evolution are forwarded by numerous studies (Meert and Lieberman, 2008).
