1. Most meteorites are stony meteorites, classed as chondrites and achondrites . 2. CHUR was determined by analysing chondrite and achondrite meteorites. 3. Could be an achondrite with anorthosite. 4. It occurs as an interstitial mineral phase between silicate minerals in enstatite chondrite and achondrite meteorites. 5. Most achondrites are also ancient rocks, and are thought to represent crustal material of differentiated planetesimals. 6. All other meteorites are achondrites : volcanic rocks from planets or asteroids large enough to have a molten core. 7. This time it's Russell, and the meteorite is an achondrite _ though probably not from Mars. 8. It was discovered in 1982 during the chemical analysis of The North Haig olivine pigeonite achondrite ( ureilite ). 9. Some scientists propose that many aubrites and enstatite achondrites are in fact impact breccias or impact-melt breccias. 10. Should the onset of melting occur the meteorite would probably be classified as a primitive achondrite instead of a chondrite.
