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]
The Murchison Province of the craton contains the Yarrabubba impact structure, at over 2 billion years old it is the oldest dated meteorite impact crater.[2]
