The 60-tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite.[1]A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon.
Example of meteorite strewnfield: distribution ellipse of Pultusk meteorite. A strewn field is the area where meteorites from a single fall are dispersed. [1] It is also often used for the area containing tektites produced by large meteorite impact. [2]
Roter Kamm (German: Red Ridge) is a meteorite crater, located in the Sperrgebiet, within the Namibian section of the Namib Desert, approximately 80 kilometres (50 mi) north of Oranjemund and 12 kilometres (7.5 mi) southwest of Aurus Mountain in the ǁKaras Region. The crater is 2.5 kilometres (1.6 mi) in diameter and is 130 metres (430 ft) deep.
The Haviland Crater, also called the Brenham Crater, is a meteorite crater in Kiowa County, Kansas. [1] [2] The oval crater is 50 feet (15 m) in diameter, making it one of the smallest impact craters in the world. Its age is estimated to be less than 1000 years. [3] It has been explored with ground-penetrating radar. [4]
Aerodynamically shaped tektites, which are mainly part of the Australasian strewn field, are splash-form tektites (buttons) which display a secondary ring or flange. The secondary ring or flange is argued as having been produced during the high-speed re-entry and ablation of a solidified splash-form tektite into the atmosphere.
The crater was formed by a meteor impact less than 70 million years ago, during the late Cretaceous Period of the Mesozoic Era. Originally called Tindouf, the 3.5-kilometer wide crater has been heavily eroded since its formation; however, its circular morphology is highlighted by exposures of older sedimentary rock layers that form roughly ...
The fragments contain an unusually high density of inclusions for an iron meteorite, which may have contributed to the disintegration of the original meteorite. The average composition of the Campo del Cielo meteorites is 3.6 ppm iridium , 87 ppm gallium , 407 ppm germanium , 0.25% phosphorus , 0.43% cobalt , and 6.67% nickel , with the ...
The Cape York meteorite, also known as the Innaanganeq meteorite, is one of the largest known iron meteorites, classified as a medium octahedrite in chemical group IIIAB. [5] In addition to many small fragments, at least eight large fragments with a total mass of 58 tonnes have been recovered, the largest weighing 31 tonnes (31 long tons; 34 ...
