The Yarrabubba impact structure is the eroded remnant of an impact crater, situated in the northern Yilgarn Craton near Yarrabubba Station between the towns of Sandstone and Meekatharra, Mid West Western Australia. [2] [3] With an age of 2.229 billion years, it is the oldest known impact structure on Earth. [1]
This result establishes Yarrabubba as the oldest recognised meteorite impact structure on Earth, extending the terrestrial cratering record back >200 million years. The age of Yarrabubba coincides, within uncertainty, with temporal constraint for the youngest Palaeoproterozoic glacial deposits, the Rietfontein diamictite in South Africa.
Traces of Catastrophe – Comprehensive technical reference on the science of impact craters; Giant-impact hypothesis – Hypothesis of the formation of the Moon; Deniliquin multiple-ring feature – Buried feature in southeast Australia, suggested to be an impact structure (520 km-diameter crater would be the largest one on Earth)
The huge Yarrabubba crater in Western Australia has been dated to 2.229bn years ago in a geological study. Oldest impact crater on Earth could throw light on ancient climate change Skip to main ...
Researchers have determined that the 45-mile-wide (70-km-wide) Yarrabubba crater in Australia formed when an asteroid struck Earth just over 2.2 billion years ago.
Yarrabubba shares a boundary with Cogla Downs Station. [1] The Yarrabubba impact structure, which takes its name from the property, is found on the margins of the station. [2] The property was advertised for sale in 1906. At this time it occupied an area of 294,000 acres (118,978 ha) and was stocked with 100 head of cattle.
A man planning a camping trip using Google Maps ran across a uniquely curved spherical pit in Quebec. It may be an ancient asteroid impact crater. A Camper Was Playing With Google Maps—and ...
The Murchison Province contains the Yarrabubba crater, which is the oldest dated meteorite impact crater, at 2229 ± 5 Ma. The crater is heavily eroded and no surface expression remains of the original structure.
