The impact has occurred in Precambrian granitic and granodioritic orthogneisses of the 1200–900 Ma old Namaqualand Metamorphic Complex which were partly covered by Gariep metasediments; the granites are invaded by quartz veins and quartz‐feldspar‐pegmatites. Figure 2a-c shows the near circularity of the crater. EARTH: Roter Kamm Crater (Namibia) ISS006-E-16068 Red line ≈ 2.5 km Blue Marble Matches Image #1 . For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface features. ... Vredefort Crater Diameter ≈ 160 km (entire structure not visible in image) National Aeronautics and Space Administration . National Aeronautics and Space Administration . The crater is about 2.5 km (1.6 miles) in diameter and is 130 meters (400 feet) deep. Located in the southern Namib Desert, the Roter Kamm crater has a diameter of 2.5 km with a raised rim, fractured with mostly radial faults, between 40 and 90 m high above the plain. The Roter Kamm crater is located in the Namib Desert, Namibia. The crater is a bowl-shaped basin filled with sand and brecciated country rock consisting of gneisses intruded by pegmatites and overlain by marble and sandstone. Abstract The well‐preserved 2.5 km diameter Roter Kamm impact crater is located in the Namib desert in Namibia. This list of impact craters in Africa includes all 20 confirmed impact craters as listed in the Earth Impact Database.These features were caused by the collision of large meteorites or comets with the Earth. The Roter Kamm crater has a diameter of about 2.5 km and is situated in the Namib Desert, SWA/Namibia. Crater Name Location Latitude Longitude Diameter (km) Age (Ma) Exposed Drilled Targed Rock** Bolid Type*** Roter Kamm: Namibia: S 27° 46' E 16° 18' However, its original floor is covered by sand deposits at least 100 meters (300 feet) thick. Roter Kamm is a moderate sized impact crater, 2.5 kilometers (1.5 miles) in diameter rim to rim, and is 130 meters (400 feet) deep. Crater Name(s) Roter Kamm: Country: Namibia: Longitude: 16 deg 18 min E: Latitude: 27 deg 46 min South: Diameter (km) 2.5 km: Age: Less than 5 million years: Description: Well preserved crater with xx m high rim, sediment filled crater floor and ejecta units exposed around the rim and outside the crater. The bright white irregular feature in the lower left corner is a small hill of exposed rock outcrop. Roter Kamm is a relatively young 2.5-km-diameter impact crater located in the southern Namib desert. References: Reimold W U and Koebert C. 2014. The rim to rim diameter of Roter Kamm is -2.5 km. About 3.7 million years ago, it was created by a meteor with the size of a large vehicle. Because of the sand coverage, impact products (breccias, impact melt, shocked rocks) are exposed exclusively in the form of ejecta on the crater rim. However, its original floor is covered by … The only exposures of Pre- cambrian granitoid rocks (granitic-granodioritic orthogneisses) are found along the partially sand covered rim (Reimold and Miller, 1989). Roter Kamm Crater, ǃNamiǂNûs Constituency, ǁKaras Region, Namibia : Meteorite crater, located in the Sperrgebiet, within the Namibian section of the Namib Desert, approximately 80 kilometres (50 mi) north of Oranjemund. Roter Kamm is a moderate sized impact crater, 2.5 kilometers (1.5 miles) in diameter rim to rim, and is 130 meters (400 feet) deep. Eolian sands are pervasive both inside and outside of the crater.
