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]
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 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.
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 ...
If the team can determine the site is a crater formed by an ancient impact event, then the next step is researching just when it happened. Of the world’s roughly 200 impact craters, 31 are ...
As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
The Deniliquin multiple-ring feature is a distinct deeply buried structure in southeast Australia. It is named after the town of Deniliquin.Its characteristics suggest that it is associated with an asteroid impact structure of diameter 520 km (320 mi), which would make it the largest one on Earth, exceeding the largest known one, the Vredefort impact structure of about 300 km (190 mi) in diameter.
The Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory , Ottawa, under the direction of Carlyle S. Beals . Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
