  2. Pilbara Craton - Wikipedia

    en.wikipedia.org/wiki/Pilbara_Craton

    The Pilbara Craton is an old and stable part of the continental lithosphere located in the Pilbara region of Western Australia. The Pilbara Craton is one of only two pristine Archaean 3.8–2.7 Ga (billion years ago) crusts identified on the Earth, along with the Kaapvaal Craton in South Africa .

    en.wikipedia.org/wiki/List_of_shields_and_cratons

    A craton is an ancient part of the Earth's continental crust which has been more or less stable since Precambrian times. Cratons whose ancient rocks are widely exposed at the surface, often with relatively subdued relief, are known as shields.

  4. Yilgarn Craton - Wikipedia

    en.wikipedia.org/wiki/Yilgarn_Craton

    The Yilgarn Craton is a large craton that constitutes a major part of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts . Zircon grains in the Jack Hills , Narryer terrane have been dated at ~4.27 Ga , with one detrital zircon dated as old as 4.4 Ga. [ 1 ]

    Nevertheless, the oldest cratons on Earth include the Kaapvaal Craton, the Western Gneiss terrane of the Yilgarn Craton (~2.9 – >3.2 Ga), the Pilbara Craton (~3.4 Ga), and portions of the Canadian Shield (~2.4 – >3.6 Ga). Parts of Dharwar Craton in India are greater than 3.0 Ga.

  6. Geology of Australia - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Australia

    The cratons appear to have been assembled to form the greater Australian landmass in the late Archaean to Mesoproterozoic, ~2400 Ma to 1,600 Ma. Chiefly the Glenburgh Orogeny is partly responsible for the assembly of the West Australian landmass by joining the Yilgarn and Pilbara cratons. The Glenburgh Orogeny is exposed in the rocks of the ...

  7. Western Australia - Wikipedia

    en.wikipedia.org/wiki/Western_Australia

    The bulk of Western Australia consists of the extremely old Yilgarn craton and Pilbara craton which merged with the Deccan Plateau of India, Madagascar and the Kaapvaal and Zimbabwe cratons of Southern Africa, in the Archean Eon to form Ur, one of the oldest supercontinents on Earth (3 – 3.2 billion years ago).

  8. Natural history of Australia - Wikipedia

    en.wikipedia.org/wiki/Natural_history_of_Australia

    The Archean rocks from the Pilbara craton contain some of the first evidence of life, primitive cyanobacterial mats known as stromatolites. Soft-bodied organisms from the Ediacaran collectively known as the Ediacaran biota are found in sandstone around the Flinders Ranges in South Australia, notably at a site known as Wilpena Pound.

  9. Paleoarchean - Wikipedia

    en.wikipedia.org/wiki/Paleoarchean

    There are only two locations in the world containing rock formations that are intact enough to preserve evidence of early life: the Kaapvaal Craton in Southern Africa and the Pilbara Craton in Western Australia. [4] The Dresser Formation is located in the Pilbara Craton, and contains sedimentary rock from the Paleoarchean Era.
