We report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. the crater formation stage, when accelerated material is ejected out of the evolving crater and injected into the crater basement. È uno dei pochi crateri meteoritici antichi in cui si siano trovati frammenti del corpo meteoritico che lo ha creato.. Voci correlate. Meteor Crater is a meteorite impact crater approximately 37 miles (60 km) east of Flagstaff and 18 miles (29 km) west of Winslow in the northern Arizona desert of the United States.The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Cañon Diablo. How is Morokweng crater hidden? Shock deformation features mark the extent of a large central uplift with a diameter of ~ 80 km, and a crater final rim of ~190±10 km. The Morokweng crater is one of the largest on Earth, and was formed at the boundary of the Jurassic and Cretaceous periods. The Morokweng crater, centered at 26 o 32' S and 23 o 32' E, is at the edge of the Kalahari Desert in northern South Africa. With a diameter of over 70 km, it is one of the ten largest craters on the planet and was created when a huge asteroid collided with the Earth about 144 million years ago. The village, which lies 140 kilometres north-west of Vryburg , was first occupied by Kgosi Maiketso in the 1790s after he broke away from the main Barolong faction at Kuruman . It has a diameter of at least 70 kilometers and is one of the largest terrestrial impact craters known today. Created by an asteroid measuring about 5-10km in diameter, the impact bowl lies hidden beneath the sand of the Kalahari Desert. Morokweng is a town in Kagisano-Molopo Local Municipality in the North West province of South Africa. From airborne radar surveys, we identify a 31-kilometer-wide, circular bedrock depression beneath up to a kilometer of ice. In Morokweng, South Africa, lies a crater larger than the city of London. More; Woodleigh Crater (WA) The Woodleigh crater, mostly hidden beneath red sand, is located on Woodleigh Station, east of Shark Bay in Western Australia. Buried beneath thousands of feet of limestone in the Yucatán Peninsula are the remains of an impact so great that it wiped out over half of the Earth’s species. Il cratere Morokweng è un cratere meteoritico di circa 70 km di diametro e di circa 144 milioni di anni di età situato in Sudafrica. The Morokweng crater in South Africa dates to roughly the same time period, although at 70km in diameter was a much larger impact than that which created Gosses Bluff. Morokweng Crater is buried beneath South Africa's Kalahari Desert: Geologists discovered it through remote sensing surveys. This depression has an elevated rim that cross-cuts tributary subglacial channels and a subdued central uplift that appears to be actively eroding. The Morokweng impact crater stands out in all available geophysical and geological datasets of South Africa as a remarkable set of concentric rings with diameters ranging from ~30 km to ~260 km. How deep is the Morokweng crater? The resulting cavity is transient, and for larger structures, such as the Morokweng crater, the excavation is accompanied by the forma-tion … Crateri da impatto sulla Terra; Cratere di Vredefort; Collegamenti esterni.
