New minerals approved by the International Mineralogical Association (IMA-CNMNC) are allocated unique symbols consistent with the main listing. New symbols are announced in the newsletters of the IMA-CNMNC. An updated "mineral symbol picker" list [7] is also available for checking on the availability of symbols prior to submission for approval.
A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material.

On Earth, the natural form of silicon carbide is a rare mineral, moissanite. [19] In the Solar System the rocky planets Mercury, Venus, Earth and Mars are 70% to 90% silicates by mass. By contrast, stars with a high ratio of carbon to oxygen may be orbited by planets that are mostly carbides, with the most common material being silicon carbide ...
