Amadeus Basin

from Wikipedia, the free encyclopedia

The Amadeus Basin (English: Amadeus Basin ) is an approximately 170,000 km² sedimentary basin of the Australian craton (mainland core) in Central Australia . It is located in the south of the Northern Territory and extends from there to the state of Western Australia . It is named after lying in the basin Lake Amadeus , which in turn after the Spanish King I. Amadeus was named.

geology

In the sedimentary basin there are up to 14 kilometers thick marine and non-marine deposits, which were formed from the Paleoproterozoic to the Neoproterozoic . The nearby Sedimentary Basin , Officer Basin , Georgina Basin, and Ngalia Basin, as well as the Amadeus Basin, were believed to have once been part of the Centralian Superbasin . This was deformed during the Petermann orogeny from the late Neoproterozoic to the Cambrian and fragmented during the Alice Springs orogeny in the Paleozoic .

In the Amadeus Basin lie the Uluṟu and Kata Tju liegena as well as the Kings Canyon .

raw materials

The Amadeus Basin contains the Mereenie oil field and the Palm Valley Gasfield near Hermannsburg , which is the most important source of energy for the Northern Territory. Much of the natural gas flows through the pipeline to Darwin , while the oil is transported from Alice Springs to the refineries in Adelaide.
