... Uluru (Ayers Rock) and Kata Tjuta (Olgas). Detrital-zircon age populations indicate that all basin sediments were derived from the Musgrave Complex, which was therefore emergent rather than covered by sediments as required by the model. In the basement, the preservation of Mesoproterozoic mica ages...
