Australia: The Land Where Time Began

A biography of the Australian continent 

Torrens River

According to 1 interpretation, the Torrens River debouched from the upland, flowing into a lake in the fault-angle depression that existed between the back slope of the Para Block and the scarp of the Eden Fault. The sediment load of the river was deposited in the lake as its velocity decreased. Coarse boulders were deposited first, that are now near the present Athelstone, followed by cobbles, near Paradise, and further to the west, gravel was deposited near Beefacres. The fluvial deposit remnants, interfingering laterally with lake beds that are fossiliferous, are still visible. This dates the Torrens River back at least 60 million years to the Eocene.
