Australia
Mountain-building And Glaciation In Victoria
The Glass House Mountains in southeastern Queensland and the Warbungle Mountains in northern New South Wales were formed by volcanism in recent times, during the Miocene Epoch, around 20 million years ago. Gold bearing deep leads can be found in basaltic lava flows along ancient valleys. The Flinders ranges in South Australia were uplifted in the modern geological era, the Cenozoic. About the same time the sea retreated from the Murray Basin in South Australia. During the Pleistocene (less than two million years ago), a 400 sq mi (103,600 ha) area around Mount Kosciusko was covered with glaciers.
