🛢 Cooper Basin

The Cooper Basin is a Permian-Triassic sedimentary geological basin in Australia. The intracratonic rift basin is located mainly in the southwestern part of Queensland and extends into northeastern South Australia. It is named after the Cooper Creek, which is an ephemeral river that runs into Lake Eyre. For most of its extent, it is overlain by the Eromanga Basin. It covers 130,000 km2.
