Description
A mineral mass that falls to the earth from outer space. There are three main categories of meteorites: 1) stony (aerolites), which account for approximately 61% of all meteorites , 2) stony irons (siderolites) account for 20%, and 3) metallic or iron meteorites (siderite) make up about 15%. The stony meteorites are composed of silicates. Stony meteorites containing small spherical inclusions are called chondrites. Tekites (australite) are small, round, glassy stones that are thought to come from meteor impact with the earth. The stony irons are a combination of silicate stone cemented with metallic Iron. Iron meteorites contain iron alloyed with about 2-50% Nickel. They also contain small amounts of Cobalt, Arsenic, and Manganese. Meteoric iron has been used since ancient times for tools and weapons.
