Vredefort Dome, approximately 120 km south-west of Johannesburg, is a representative part of a larger meteorite impact structure (astrobleme). Dating back 2,023 million years, it is the oldest astrobleme found on Earth so far. With a radius of 190 km, it is also the largest and the most deeply eroded. Vredefort Dome bears witness to the world's greatest known single energy-release event, which caused devastating global change, including, according to some scientists, major evolutionary changes. It provides critical evidence of the Earth's geological history and is crucial to our understanding of the evolution of the planet. Despite this, geological activity on the Earth's surface has led to the disappearance of evidence from most impact sites and Vredefort is the only example to provide a full geological profile of an astrobleme below the crater floor, allowing research into the genesis and development of an astrobleme immediately post-impact.

The site contains high quality and accessible geological (outcrop) sites that demonstrate a range of geological evidences of a complex meteorite impact structure. The rural and natural landscapes of the serial property help to portray the magnitude of the ring structures resulting from the impact.
