Meteor Crater, or Barringer Crater, is an impact crater about 37 mi (60 km) east of Flagstaff and 18 mi (29 km) west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite , after the adjacent Canyon Diablo .
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.
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. [11] The source of the enormous Australasian strewnfield (c. 780 ka) is a currently undiscovered crater probably located in Southeast Asia. [12] [13]
Middlesboro crater is a 3-mile (4.8 km) diameter meteorite impact crater in which Middlesboro, Kentucky, is located. The crater was identified in 1966 when Robert Dietz discovered shatter cones in sandstone, which led to the further identification of shocked quartz.
"Holsinger Meteorite", the biggest recovered fragment of the Canyon Diablo meteorite Example of a small (90mm) fragment of the meteorite. The biggest fragment ever found is the Holsinger Meteorite, weighing 639 kilograms (1,409 lb), now on display in the Meteor Crater Visitor Center on the rim of the crater. Other famous fragments:
The Odessa Meteor Crater is a meteorite crater in the southwestern part of Ector County, southwest of the city of Odessa of West Texas, United States. It is accessible approximately 3 mi (5 km) south of Interstate 20 at Exit 108 (Moss Road). [ 1 ]
The impactor is considered to have been a stony meteorite about 2 km (1.2 mi) in diameter. The site at the time was the shore of a shallow inland sea, [ 7 ] the Western Interior Seaway . The impact disrupted granite , gneiss , and shales of the Precambrian basement as well as sedimentary formations of Paleozoic age, Devonian through Cretaceous .
The Decorah crater has been conjectured as being part of the Ordovician meteor event. [ 348 ] [ better source needed ] Several twin impacts have been proposed, such as the Rubielos de la Cérida and Azuara (30–40 Ma), [ 349 ] Cerro Jarau and Piratininga (c. 117 Ma), [ 73 ] and Warburton East and West (300–360 Ma).
