Uluru / Ayers Rock is a massive rock structure located in Northern Territory, Australia. Consisting of red sandstone that is relatively resistant to weathering, Uluru / Ayers Rock prominently rises 348 meters above the surrounding lowlands. The structure has likely been formed by sediment deposition in alluvial fans associated with mountain uplift during the late Neoproterozoic to early Cambrian (~ 550 million years ago), followed by tilting in the Paleozoic (~ 400 million years ago). Subsequent erosion of the surrounding rocks and the formation of iron oxides further shaped Uluru / Ayers Rock into its present state as a majestic red mountain.
