Australia: The Land Where Time Began

A biography of the Australian continent 

Larapinta Sea

A warm shallow sea that covered much of Australia during the Ordovician. In the sea were coral reefs, a wide diversity of many invertebrate groups, particularly the molluscs. In places like the Georgina Basin carbonate deposits formed, and in the Daly River Basin there are halite crystals in the sediments. The country of the northern block had low relief, but that of the southern block was rugged and volcanic.
