1) Vredefort crater
Vredefort crater is the largest verified impact crater on Earth, more than 300 km across. It is located in the present-day Free State Province of South Africa and named after the town of Vredefort, which is situated near its centre. Although the crater itself has long since eroded away, remaining geological structures at its centre are known as the Vredefort Dome or Vredefort impact structure. In 2005, the Vredefort Dome was added to the list of UNESCO World Heritage Sites for its geologic interest.
2) Sudbury Basin
The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geologic structure in Ontario, Canada. It is the second-largest known impact crater or astrobleme on Earth, as well as one of the oldest.
The basin is located on the Canadian Shield in the city of Greater Sudbury, Ontario. The former municipalities of Rayside-Balfour and Valley East lie within the Sudbury Basin, which is referred to locally as "The Valley". The urban core of the former city of Sudbury lies on the southern outskirts of the basin.
3) Acraman crater
Acraman crater is a deeply eroded impact crater in the Gawler Ranges of South Australia.[1] Its location is marked by Lake Acraman, a circular ephemeral playa lake about 20 km in diameter.
The discovery of the crater and independent discovery of its ejecta were first reported in the journal Science in 1986. The evidence for impact includes the presence of shatter cones and shocked quartz in shattered bedrock on islands within Lake Acraman.
4)Manicouagan crater
The Manicouagan Crater is one of the oldest known impact craters and is the largest 'visible' impact crater on Earth, located primarily in Manicouagan Regional County Municipality in the Côte-Nord region of Québec, Canada, about 300 km (190 mi) north of the city of Baie-Comeau. At roughly 213-215 million years old, Manicouagan is one of the oldest large astroblemes still visible on the surface.
5) Kara crater
Kara is a meteor crater in the Yugorsky Peninsula, Nenetsia, Russia. It is 65 km in diameter and the age is estimated to be 70.3 ± 2.2 million years old.
