[8] The granting of prospecting rights around the edges of the crater has led environmental interests to express fear of destructive mining. [3] This central peak uplift, or dome, is typical of a complex impact crater, where the liquefied rocks splashed up in the wake of the meteor as it penetrated the surface. Struik Publishers, Cape Town. Clicking on the links in the column "Continent" will give a list of craters for that continent. 6. One of the first microcontinents to form was the Kaapvaal Craton, which is exposed at the centre of the Vredefort Dome, and again north of Johannesburg.

The original crater is believed to have sprawled 160 miles (260 km).

Is this the funniest animal picture ever? To keep the lists manageable, only the largest craters within a time period are included. The oldest impact crater on Earth is also the largest.

Our first lake-filled crater, Manicouagan in Quebec is one the largest and best-preserved crater on the planet. Geological processes, such as erosion and plate tectonics, have destroyed most multiple-ring craters on Earth.

By Although the crater itself has long since been eroded away, the remaining geological structures at its centre are known as the Vredefort Dome or Vredefort impact structure.

[28] The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian craters are grouped together per EID convention. (2005).

The effects of asteroid impacts linger for billions of years.

Some 35 million years ago, a meteorite crashed into carbon-rich graphite rock deposits in Siberia, and the impact's immense pressures and temperatures converted the carbon into diamonds. Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. But scientists got a surprise when they drilled into the crater looking for rock samples to confirm the impact. New York, The Vredefort Dome in the centre of the crater is home to four towns: Parys, Vredefort, Koppies and Venterskroon. Chicxulub crater's discovery clinched what was once a wild theory: that a meteor impact wiped out the dinosaurs. An artist’s concept of the giant asteroid or comet plunging into what is now Chesapeake Bay 35 million years ago. For example, the Wilkes Land crater has been connected to the massive Permian–Triassic extinction event. In 2019, scientists from the University of the Free State discovered 8,000-year-old carvings made by the Khoisan people. On 19 December 2011, a broadcasting license was granted by ICASA to a community radio station to broadcast for the Afrikaans- and English-speaking members of the communities within the crater. The crater's age is estimated to be 2.023 billion years (± 4 million years),[1] which places it in the Paleoproterozoic Era.

quartzites and banded ironstones),[3][6] they form the prominent arc of hills that can be seen to the northwest of the crater centre in the satellite picture above. The Earth's crust was wholly or partially molten during the Hadean Eon. The crater is calculated to be 2.023 billion years old (± 4 million years), with impact being in the Paleoproterozoic Era. Norman, N., Whitfield, G. (2006) ‘’Geological Journeys’’. Morokweng Crater. The curving western shoreline of Chesapeake Bay takes its shape from the 53-mile-wide (85 km) marine crater. The largest unconfirmed craters 200 km (120 mi) or more are significant not only for their size, but also for the possible coeval events associated with them. [10] The EID gives a size of about 50 m (160 ft) for Campo del Cielo, but other sources quote 100 m (330 ft).

Johannesburg is where the Witwatersrand Basin (the yellow layer) is exposed at the "present surface" line, just inside the crater rim, on the left. Little remains at the surface of the 37-mile-wide (60 km) crater, which wasn't discovered until the 1990s.

List of possible impact structures on Earth, Planetary and Space Science Centre University of New Brunswick Fredericton, Hartebeesthoek Radio Astronomy Observatory, "The Vredefort Dome: Centre of the World's Largest Meteorite Impact Structure!

Worms Frozen for 42,000 Years in Siberian Permafrost Wriggle to Life.

Asteroid impact date: Estimated 145 million years ago The global distribution of known impact structures apparently shows a surprising asymmetry,[29] with the small but well-funded European continent having a large percentage of confirmed craters. Confirmed impact craters listed by size and age, 250 (uncertain, estimated to be Late Palaeozoic).

[3][5] The rocks form partial concentric rings around the crater centre today, with the oldest, the Witwatersrand rocks, forming a semicircle 25 km (16 mi) from the centre. Vredefort crater in South Africa, also called the Vredefort Dome, was originally 185 miles (300 kilometers) across, scientists estimate.

234–37 (16 January 1992), Povenmire, Harold; Liu, W.; Xianlin, Luo; (1999), Glass, Billy P.; Pizzuto, James E.; (1994). It is named after the town of Vredefort, which is near its centre. Not to scale. 'Lost' chameleon rediscovered after a century in hiding. A thin layer of exotic iridium metal from a meteor impact had been detected worldwide at Cretaceous mass extinction before Chicxulub was found. Bland, Phil A.; de Souza Filho, C. R.; Timothy Jull, A. J.; Kelley, Simon P.; Hough, Robert Michael; Artemieva, N. A.; Pierazzo, E.; Coniglio, J.; Pinotti, Lucio; Evers, V.; Kearsley, Anton; (2002); Schultz, Peter H.; Lianza, Ruben E.; (1992) "Recent grazing impacts on the Earth recorded in the Rio Cuarto crater field, Argentina", Nature 355, pp. [11], However, the currently unknown source of the enormous Australasian strewnfield (c. 780 ka) could be a crater about 100 km (62 mi) across. Here on Earth, flying space debris triggered mass extinctions, but the same deadly asteroids might also have delivered the seeds of life soon after Earth was born. The overlying Ventersdorp lavas and the Transvaal Supergroup which were laid down between 700 and 80 million years before the meteorite strike, were similarly distorted by the formation of the 300-kilometre-wide (190 mi) crater.

It would have been larger than the 250 km (160 mi) Sudbury Basin and the 180 km (110 mi) Chicxulub crater. In 2005, the Vredefort Dome was added to the list of UNESCO World Heritage sites for its geologic interest.

The graph also indicates the period during which banded ironstone formations were formed on earth, indicative of an oxygen-free atmosphere.

The asteroid that hit Vredefort is estimated to have been one of the largest ever to strike Earth (at least since the Hadean Eon some four billion years ago), thought to have been approximately 10–15 km (6.2–9.3 mi) in diameter. The drill brought back a 10-inch (25 centimeter) fragment of the original meteorite from about 842 yards (770 meters) below the surface.

Morokweng formed 145 million years ago and is 44 miles (70 km) wide.

Sudbury crater in Ontario, Canada, clocks in at 81 miles (130 km) wide and 1.85 billion years old, close in age and size to Vredefort crater in South Africa. W indicates when the Witwatersrand Supergroup was laid down, C the Cape Supergroup, and K the Karoo Supergroup. Craters with diameter 20 km (12 mi) or more are all older than 10 Ma, except possibly Karakul, 52 km (32 mi), whose age is uncertain.

Impact ejecta from the crater can be found in the Flinders Range 185 miles (300 km) to the east, among rocks with fossils of the first complex life forms on Earth.

The Witwatersrand rocks are followed, in succession, by the Ventersdorp lavas at a distance of about 35 km (22 mi) from the centre, and the Transvaal Supergroup, consisting of a narrow band of the Ghaap Dolomite rocks and the Pretoria Subgroup of rocks, which together form a 25-to-30-kilometre-wide (16 to 19 mi) band beyond that.

The remains of the meteorite that created this crater were still in its depth. [1] To keep the lists manageable, only the largest craters within a time period are included.

p. 89–90, 102–107, 134–136. The largest in the last one million years is the 14-kilometre (8.7 mi) Zhamanshin crater in Kazakhstan and has been described as being capable of producing a nuclear-like winter.

The original crater is estimated to have had a diameter of roughly 300 km (190 mi),[2] but that has been eroded. The Vredefort crater /ˈfrɪərdəfɔːrt/ is the largest verified impact crater on Earth.
