What mineral is Ayers Rock made of?

Answer 1

Ayers Rock, or Uluru, in central Australia, is the second largest monolith in the world, second only to Mt Augustus, in Western Australia. Explorer William Gosse, of the South Australian Survey Department, became the first European explorer to visit Ayers Rock, which he sighted on 18 July 1873.

It is not known how ir why Uluru developed, or where it came from, but judging by the position of the rock strata, there is evidence to suggest it formed as the result of a sudden flood, with the sand particles adhering over a short period of time. Uluru-Ayers Rock and the nearby Olgas (also known as Kata Tjuta) are part of the same sandstone slab beneath the Earth's surface. Parts of this sandstone slab tilted 90 degrees, which is why the sandstone layers of Ayers Rock actually run almost vertically, rather than horizontally. Over time, wind and rain gradually eroded away the softer parts of the rock. It is estimated that only one-eighth of Ayers Rock is actually visible above the surface - the rest of it is underground, continuing for 5-6 kilometres.

Answer 2

Uluru/Ayers Rock is a rock in the Northern Territory in Australia. It is made of red sandstone. It is not the largest rock in the world, being second to Australia's Mt Augustus, which is almost twice the size. However, Uluru/Ayers Rock is more spectacular in appearance, being devoid of all vegetation.

Answer 3

Ayers Rock is a large sandstone rock. It (Uluru) is primarily composed of coarse-grained arkose (a type of sandstone characterized by an abundance of feldspar) and some conglomerate. Average composition is 50% feldspar, 25-35% quartz and up to 25% rock fragments; most feldspar is K-feldspar with only minor plagioclase as subrounded grains and highly altered inclusions within K-feldspar. The grains are typically 2-4 millimetres (0.079-0.16 in) in diameter, and are angular to subangular; the finer sandstone is well sorted, with sorting decreasing with increasing grain size.[ The rock fragments include subrounded basalt, invariably replaced to various degrees by chlorite and epidote.

Answer 4

Mount Olga, or Kata-Tjuta, and Uluru-Ayers Rock are composed of sandstone.

Answer 5

sand stone

Answer 6

Uluru/Ayers Rock, in Australia, is a sandstone monolith. It is made up of around 50% feldspar, 25–35% quartz and up to 25% rock fragments.

Answer 7

Ayers Rock, also known as Uluru, is mainly composed of a type of sandstone called arkose. This sandstone contains a high proportion of feldspar minerals, giving Uluru its distinctive red color.

Answer 8

No. Ayers Rock/Uluru is sedimentary rock.
