Abstract
Achondrites are meteorites that formed by varying degrees of melting and differentiation on their parent bodies. They are divided into asteroidal and planetary achondrites. Asteroidal achondrites are remnants of differentiated planetesimals and protoplanets that existed shortly after the formation of the Solar System. They are partially to totally melted rocks. Planetary achondrites represent material derived from large planetary bodies (the Moon and Mars) and formed by complex igneous processing.
