The Sturtian glaciation was a glaciation during the Cryogenian period. During the Cryogenian the Earth experienced repeated large scale glaciations, the Sturtian glaciation being the longest one, lasting about 60 million years.[1]
Naming
The Sturtian glaciation is named after the Sturt River Gorge (Near Bellevue Heights, South Australia).
