Chondrite (Sahara NWA 869)

Chondrites are stony meteorites, natural extraterrestrial rocks named after the chondrules they contain: small, nearly spherical silicate droplets that formed in the early solar system. At over 4.5 billion years old they are among the most primitive rocks known and have never been melted. They are the most common meteorites, about 86% of all meteorites recovered.
