Geological story
Australia has one of the longest intact geological histories of any nation on earth and has been assembled from an extensive series of terranes being rafted in on via tectonic subduction. Its current neighbours on the globe were previously connected together in Gondwana before being rifted apart. Rocks from the neighbouring continents and oceans tell the story of Australia’s most recent tectonic history.
Rocks to show: Sibling rocks from different contents having been separated by rifting. Rocks showing the results of tectonic action. Rocks with tectonic significance from neighbouring countries and islands.
