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.
A peridot formed as a result of volcanic activity tends to contain higher concentrations of lithium, nickel and zinc than those found in meteorites. [ 8 ] [ full citation needed ] Olivine is an abundant mineral, but gem-quality peridot is rather rare due to its chemical instability on Earth's surface.
Pyrrhotite has the formula Fe (1-x) S (x = 0 to 0.2) which is iron deficient. As troilite lacks the iron deficiency which gives pyrrhotite its characteristic magnetism, troilite is non-magnetic. [3] Troilite can be found as a native mineral on Earth but is more abundant in meteorites, in particular, those originating from the Moon and Mars.
Some presolar grains in primitive meteorites consist of hibonite. Hibonite also is a common mineral in the Ca-Al-rich inclusions found in some chondritic meteorites . Hibonite is closely related to hibonite-Fe (IMA 2009-027, (Fe,Mg)Al 12 O 19 ) ) an alteration mineral from the Allende meteorite . [ 4 ]

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 ...
Widmanstätten pattern showing the two forms of Nickel-Iron, Kamacite and Taenite, in an octahedrite meteorite Taenite is a mineral found naturally on Earth mostly in iron meteorites . It is an alloy of iron and nickel , with a chemical formula of Fe , Ni and nickel proportions of 20% up to 65%.
A Belgian-Dutch team of scientists says it has created the first “treasure map” showing where meteorites may be found On the hunt for meteorites, researchers look to a data-based 'treasure map ...
