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.
Stony-iron meteorites or siderolites are meteorites that consist of nearly equal parts of meteoric iron and silicates.This distinguishes them from the stony meteorites, that are mostly silicates, and the iron meteorites, that are mostly meteoric iron.
In meteoritics, a meteorite classification system attempts to group similar meteorites and allows scientists to communicate with a standardized terminology when discussing them. Meteorites are classified according to a variety of characteristics, especially mineralogical , petrological , chemical , and isotopic properties.
A "meteorite fall", also called an "observed fall", is a meteorite collected after its arrival was observed by people or automated devices. Any other meteorite is called a "meteorite find". [ 43 ] [ 44 ] There are more than 1,100 documented falls listed in widely used databases, [ 45 ] [ 46 ] [ 47 ] most of which have specimens in modern ...
Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, [3] with the exception of the IIE iron meteorite group. [4]
The CM meteorite Murchison has over 96 extraterrestrial amino acids and other compounds including carboxylic acids, hydroxy carboxylic acids, sulphonic and phosphonic acids, aliphatic, aromatic and polar hydrocarbons, fullerenes, heterocycles, carbonyl compounds, alcohols, amines and amides.
The Willamette Meteorite weighs about 34,200 pounds (15,500 kg). It is classified as a type III iron meteorite, being composed of over 91% iron and 7.62% nickel, with traces of cobalt and phosphorus. The approximate dimensions of the meteorite are 10 feet (3 m) tall by 6.5 feet (2 m) wide by 4.25 feet (1.3 m) deep.
The IAB meteorites are composed of meteoric iron (kamacite and taenite) and silicate inclusions.Structurally they can be hexahedrites, fine to coarse octahedrites, or even ataxites. [2]
