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]
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.
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.
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 ...
The following structures are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed.
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]

This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
