Summary

Description
English: The distribution of Archaean and Proterozoic basement rocks in Australia. The three Archaean cratons were the nuclei around which three continental masses amalgamated (by accretion of terranes): the North-, West-, and East-Australian cratons. The three most likely docked during the Grenville Orogeny around 1.4 and 1.0 billion years ago. The east and southeast part of Australia (bordering the Pacific coast) is younger and must have accumulated at a later stage. The Proterozoic consists of mobile belts (orogens) as well as (deformed) basins.
