The structure's central uplift is known as the Vredefort Dome. 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.
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 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.
A schematic diagram of the area surrounding the Vredefort Dome, where a massive meteor created an impact crater 300 km in diameter 2,02 billion years ago. The red dot represents the point of impact. The outer circle has a radius of 150 km, and indicates the approximate location of the crater rim.
The Vaal River (dark line) emerges from the dark crescent formed by the Vredefort Dome (at bottom right), while the Magaliesberg forms another crescent (in the top right corner), with tailings of platinum mines visible along its northern flank
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 ...
