Quick Summary
Ureilites are a rare type of achondrite meteorite, meaning they lack chondrules, which are small, spherical objects found in many meteorites that formed in the early solar nebula. Achondrites, like ureilites, resemble terrestrial igneous rocks and are believed to have formed from melting and crystallization processes within asteroids. Ureilites are distinguished by their composition, which includes olivine and pyroxene, and often contain graphite and diamond. They represent about 4 percent of all known meteorites.1
