The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. [2] [3] The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of ...
Vredefort (locally / ˈ f r ɪər d ə f ɔːr t /, Afrikaans: [ˈfriədəfɔrt]) is a small farming town in the Free State province of South Africa with cattle, peanuts, sorghum, sunflowers and maize being farmed. It is home to 3,000 residents.
Venterskroon is home to the Vredefort Dome Information Centre. The Vredefort Dome is the center of the Vredefort impact structure. This impact structure is the world's largest, oldest, and most deeply eroded complex asteroid impact structure in the world, and has been listed by UNESCO as World Heritage Site [ 2 ] [ 3 ]
The following tables list geological features on Earth that are known impact events as well as possible, but for which there is currently no confirming scientific evidence in the peer-reviewed literature, impact events. In order for a structure to be confirmed as an impact crater, it must meet a stringent set of well-established criteria. Some ...
An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, [2] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. [3]
If it is indeed a crater, it would be the largest ever found on Earth. ... That would mean it is far bigger than South Africa’s roughly 186-mile-wide Vredefort impact structure, considered to be ...
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] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
Researchers believe they’ve discovered the world’s largest asteroid impact crater in New South Wales, Australia. They think the impact may have happened between 445 and 443 million years ago.
