What is Uluru Ayers Rock made of ?


  • Uluru is a huge chunk of rock, known as a monolith, set the middle of Australia.
  • 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.
  • The 300 million-year-old rock is comprised of sand, feldspar (various crystalline minerals) and rock, and originally hailed from a sea floor. A large chunk is above ground today (348m), and the flat top and grooved sides are a result of weathering. Uluru was discovered by William Gosse in the 1800s, who named it after the Chief Secretary to South Australia, Henry Ayers.
  • Uluru is the Aboriginal and official name. Ayers Rock is the most commonly used name, especially outside Australia.


  • The intriguing sculpted shapes, valleys and ridges, caves, potholes and plunge pools are the result of the last few hundreds of millions of years of erosion. The flaky surface is due to chemical decomposition.
