Around 500 million years ago, the whole area became covered in sea. Sand and mud fell to the bottom and covered the seabed, including these fans. The weight of the new seabed turned the fans into rock. The sandy fan became sandstone (Uluru) while the rocky fan became conglomerate rock (Kata Tjuta).

Why do people go to Ayers Rock?

Beautiful sunrises and sunsets, ancient landscapes, and fascinating culture are just a few of the reasons you should visit Uluru. Often overlooked by domestic and international travelers, the 'Australian Red Center' offers its visitors a more secluded and spiritual experience.

What is under Uluru?

Uluru rock is composed of arkose, a coarse grained sandstone rich in the mineral feldspar. The sandy sediment, which hardened to form this arkose, was eroded from high mountains composed largely of granite. Kata Tjuta rock is a conglomerate - gravel consisting of pebbles, cobbles and boulders cemented by sand and mud.
