Meteorite Gemstone & Information | Gemopedia by JTV | Gemopedia™
A meteorite is a solid piece of debris that originated in outer space, entered Earth's atmosphere and survived impact with the surface. These fragments are usually from comets or asteroids, or debris from the Moon or Mars. There are several known meteorite impact sites, including Campo Del Cielo Argentina, the Sikhote Alin Mountains In Primorye Russia and the Sahara Desert region of Morocco. Meteorites are separated into three types based on their metal content: iron, stony-iron and iron.

Chondrites have chondrules or round grains formed by distinct minerals and are the most common meteorites found. Achondrites have been reprocessed through to melting and recrystalliazation and lack chondrules; they have a similar appearance to basalts or plutonic rocks. Iron meteorites are made up mostly of an iron-nickel alloy called meteoric iron. Stoney-iron meteorites are made up of a iron-nickel matrix with silicate materials.
