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]
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 ...
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.
This list of impact structures (including impact craters) on Earth contains the majority of the 194+ confirmed impact structure given in the Earth Impact Database as of 2024. [1] Alphabetical lists for different continents can be found under Impact structures by continent below.
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.
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 impact structure was formed during the Paleoproterozoic Era, 2.023 billion (± 4 million) years ago. It is the second-oldest known impact structure on Earth, after Yarrabubba. In 2005, the Vredefort Dome was added to the list of UNESCO World Heritage Sites for its geologic interest.
Investigators are piecing together the cause of the wildfire that claimed 11 lives, destroyed thousands of structures, and may be linked to a smaller blaze just days earlier.
