Marinoan glaciation
{'<entity_0>': 'Marinoan glaciation', '<entity_1>': 'glacial period'}
[['Marinoan glaciation', 'instance of', 'glacial period']]
The <entity_0> was a period of worldwide <entity_1> that lasted from approximately 650 to 635 Ma (million years ago) during the Cryogenian period. However, the term <entity_0> came into common usage because it was the <entity_1> that occurred during the Marinoan Epoch, as distinct from the earlier <entity_1> during the Sturtian Epoch (the time period of deposition of the older Sturtian Series). The term <entity_0> was later applied globally to any glaciogenic formations assumed (directly or indirectly) to correlate with Mawson's original Elatina <entity_1> in South Australia.
