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 ...
The town was established in 1876 on a farm called Visgat, on the Vredefort impact structure, the largest and oldest visible bolide impact crater in the world (with a diameter of 300 kilometres (190 mi)).
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]
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 ...
That would mean it is far bigger than South Africa’s roughly 186-mile-wide Vredefort impact structure, considered to be the biggest in the world, Glikson said. ... He estimated the crater to be ...
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 ]
There appeared to be the remains of about 20 structures buried in the crater, the researchers said, and they were built in a circular formation. ... → Elaborate 600-year-old castle — complete ...
The Vredefort impact event, which occurred around 2 billion years ago in Kaapvaal Craton (what is now South Africa), caused the largest verified crater, a multi-ringed structure 160–300 km (100–200 mi) across, forming from an impactor approximately 10–15 km (6.2–9.3 mi) in diameter. [67] [68]
