Geology
Mount Augustus is composed of sandstone and conglomerate, a formation known to geologists as the Mount Augustus Sandstone, which overlies older granite near its northern end. The Mount Augustus Sandstone was deposited by ancient river systems and is somewhat younger than the 1.64 billion year old granite beneath. The originally horizontal sediments have been folded into an asymmetric anticline by later tectonic movements.
