Adelaide Superbasin

The Adelaide Superbasin (previously known as the Adelaide Geosyncline and Adelaide Rift Complex) is a major Neoproterozoic to middle Cambrian geological province in central and south-east South Australia, western New South Wales, and western Victoria. It consists of a thick pile of sedimentary rocks and minor volcanic rocks that were deposited on the eastern margin of the Australian continent during the time of breakup of the supercontinent Rodinia. The Adelaide Superbasin has been the subject of much research, as it contains geological evidence for the breakup of Rodinia; two Snowball Earth events (the Sturtian and Marinoan glaciations); the Neoproterozoic oxygenation event, the transition to mostly eukaryotic life; and the Ediacaran Fauna.
