Uluru mapping and describing the geological history of the area, geologists refer to the rock strata making up Uluru as the Mutitjulu Arkose, and it is one of many sedimentary formations filling the Amadeus Basin. Uluru is dominantly composed of coarse-grained arkose (a type of sandstone characterized by an abundance of feldspar) and some conglomerate.
