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.

The Murchison Province of the craton contains the over 2 billion year old Yarrabubba impact structure, previously regarded as the oldest dated meteorite impact crater, until the discovery of evidence such as shatter cones confirming the existence of the 3.47 billion year old North Pole Crater near Marble Bar in the Pilbara.
