and Pilbara cratons. The Capricorn Orogeny is exposed in the rocks of the Bangemall Basin, Gascoyne Complex granite-gneisses and the Glengarry, Yerrida and Padbury basins. Unknown Proterozoic orogenic belts, possibly similar to the Albany Complex in southern Western Australia and the Musgrave Block, represent the Proterozoic link between the Yilgarn and Gawler cratons, covered by the Proterozoic-Palaeozoic Officer and Amadeus basins. Aboriginal Indigenous Australians have lived in the desert for at least 50,000 years and occupied all Outback regions, including the driest deserts, when Europeans first entered central Australia in the 1800s. Many Indigenous Australians retain strong physical and cultural links to their traditional country and are legally recognised as the traditional owners of large parts of the Outback under Commonwealth Native Title legislation. Aboriginal tribes and clans have been nomadic in the desert areas for thousands of years. They subsisted on the local flora and fauna, now known as bush food, and made sure that their sources of drinking water remained intact. The nomads moved in clearly demarcated tribal areas. For example, important tribes living in the desert areas include the Arrernte, Luritja and Pitjantjatjara. The latter tribe's sphere of influence extended from Uluṟu to the Nullarbor Plains. The Dieri tribe lives in a large area of ​​the Simpson, Strzelecki and Tirari deserts. The rock art and archaeological site at Karnatukul was, until recently, estimated to have been inhabited for up to 25,000 years, and known as the site of the oldest continuous recorded occupation in the Western Desert cultural region. Karnakatul shows one of the earliest uses of firewood, and habitation continued through times of extreme climate change, when the desertification occurred as the polar ice sheets expanded. The oldest examples of rock art, in Western Australia's Pilbara region and the Olary district of South Australia, are estimated to be up to around 40,000 years old. The oldest firmly dated evidence of rock art painting in Australia is a charcoal drawing on a small rock fragment found during the excavation of the Narwala Gabarnmang rock shelter in south-western Arnhem Land in the Northern Territory. The isolated desert areas remained undeveloped for a long time. For example, the Spinifex People first had contact with whites in the 1950s, when they were expelled from their tribal lands because of nuclear weapons testing (1950–1963) by the British and Australian governments.
