Australia: The Land Where Time Began

A biography of the Australian continent 

Kanimblan Orogeny

Though the climate was gradually warming, the Permian was still a cold time, the higher areas still being covered with alpine glaciers, especially on the mountains in the southeast of the continent. Much of this mountainous country had risen during the Kanimblan Orogeny of the Carboniferous. During this orogeny, a wide belt extending from Tasmania to Cape York underwent a period of uplift and deformation. It was the most severe orogenic event known to affect the Tasman Geosyncline. Ice-rafted boulders and drop stones are present in sediment deposited in the Sydney Basin during the Permian, evidence that the area was still subject to freezing winters. Trees petrified in this period give further evidence of a strongly seasonal climate in the growth rings in their wood.
