Dating of Neoproterozoic and Cambrian orogenies in Tasmania

The earliest geological history is recorded in rocks from over 1,270 million years ago. Older rocks from western Tasmania and King Island were strongly folded and metamorphosed into rocks such as quartzite. After this there are many signs of glaciation from the Cryogenian, as well as the global warming that occurred at the start of the Ediacaran period. An orogeny folded the older Precambrian rocks.
