The Amadeus Basin is a large (~170,000 km2) intracratonic sedimentary basin in central Australia, lying mostly within the southern Northern Territory, but extending into the state of Western Australia.
Local deposition of up to 14 km of marine and non-marine sedimentary rocks took place from the Neoproterozoic to the late Paleozoic.
The basin was locally deformed during the Petermann Orogeny (late Neoproterozoic — Cambrian), and more extensively during the Paleozoic Alice Springs Orogeny, events that fragmented the former Centralian Superbasin.
The Amadeus Basin contains the producing Mereenie Oil Field near Kings Canyon and Palm Valley Gas Field near Hermannsburg, which supply most of the energy resources to the Northern Territory.
