A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material. [citation needed] This is a list of those minerals, excluding minerals also commonly found in terrestrial rocks. As of 1997 there were approximately 295 mineral species which have been identified in meteorites. [1]
Peridot can be found in mafic and ultramafic rocks occurring in lava and peridotite xenoliths of the mantle. The gem occurs in silica-deficient rocks such as volcanic basalt and pallasitic meteorites. Along with diamonds, peridot is one of only two gems observed to be formed not in Earth's crust, but in the molten rock of the upper mantle. [1]
A Meteorite mineral is a mineral found chiefly or exclusively within meteorites, as opposed to minerals also found commonly on Earth, such as Olivine. The main article for this category is List of meteorite minerals .
Moldavite (Czech: vltavín) is a forest green, olive green or blue greenish vitreous silica projectile glass formed by a meteorite impact in southern Germany (Nördlinger Ries Crater) [3] that occurred about 15 million years ago. [4]
Between 1911 and 1913, 33 fragments of the meteorite were collected in the vicinity of Gibeon and brought to the capital Windhoek. They weighed between 195 and 506 kilograms (430 and 1,116 lb) and were first stored, then displayed at the Zoo Park as a single heap. In 1975 a public fountain displaying the meteorite fragments was planned.
A few meteorites were found in Antarctica between 1912 and 1964. In 1969, the 10th Japanese Antarctic Research Expedition found nine meteorites on a blue ice field near the Yamato Mountains. With this discovery, came the realization that movement of ice sheets might act to concentrate meteorites in certain areas. [67]
The most carbon-rich meteorites, with abundances up to 0.7% by mass, are ureilites. [ 6 ] : 241 These have no known parent body and their origin is controversial. [ 7 ] Diamonds are common in highly shocked ureilites, and most are thought to have been formed by the shock of the impact with either Earth or other bodies in space.
In 2020, researchers at Australian National University found by accident they were able to produce lonsdaleite at room temperatures using a diamond anvil cell. [ 28 ] [ 29 ] In 2021, Washington State University's Institute for Shock Physics published a paper stating that they created lonsdaleite crystals large enough to measure their stiffness ...
