Geology of Queensland

The geology of Queensland can be subdivided into several regions with different histories. Along the east coast is a complex of Palaezoic to Cainozoic rocks while much of the rest of the state is covered by Cretaceous and Cainozoic rocks. A Precambrian basement is found in the north west and Cape York regions. The Thomson Orogen occurs in the central and southern parts of Queensland, but is mostly covered by younger basins.

The North Queensland Orogen is along the coast from Charters Towers to Princess Charlotte Bay. The Bowen Gunndedah Sydney basin can be considered as one system that extends into Queensland. The New England Orogen is on the coastal parts from the border with New South Wales north to Ayr.
