- ‘It has been identified in carbonaceous achondrite and iron meteorites.’
- ‘Based on their texture, stone meteorites are divided into two types, the chondrites and the achondrites.’
- ‘Primitive achondrites then experienced varying degrees of melting, thermal processing, and recrystallization.’
- ‘The shop offers a wide range of Lunar and Martian meteorites along with many rare achondrites and chondrites.’
