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]
It forms about one percent of the lunar crust and is present in any rock or meteorite originating from moon. In particular, all basalts brought by the Apollo 11, 12, 15 and 16 missions contain about 1% of troilite. [6] [13] [14] [15] Troilite is regularly found in Martian meteorites (i.e. those originating from Mars). Similar to the Moon's ...
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 .
They were first discovered in the 19th century by ore prospectors who mistook the shiny metal inclusions for silver and thought they had found an outcrop of a silver ore deposit. Later when an analysis was made and nickel-iron was found, the true nature as a meteorite was established. The meteorite was called Vaca Muerta. [3]
CM chondrites are a group of chondritic meteorites which resemble their type specimen, the Mighei meteorite. The CM is the most commonly recovered group of the ' carbonaceous chondrite ' class of meteorites, though all are rarer in collections than ordinary chondrites .
The Orconuma meteorite is classified as an H3-4 chondrite. This classification indicates that it is a type of stony meteorite that is rich in olivine and pyroxene, and it originated from the asteroid belt. The H3-4 classification also suggests that it underwent minimal thermal metamorphism on its parent body. [6]
The Maine Mineral and Gem Museum wants to add to its collection, which includes moon and Mars rocks, Pitt said, so the first meteorite hunters to deliver a 1-kilogram (2.2-pound) specimen will ...
Brenham [1] is a pallasite meteorite found near Haviland, a small town in Kiowa County, Kansas, United States. Pallasites are a type of stony–iron meteorite that when cut and polished show yellowish olivine (peridot) crystals. The Brenham meteorite is associated with the Haviland Crater.
