He Was A Mineralogist of Achondrites

Aaron was lying down on a wide green field where he witness the entry of what seems like a rock from outer space entering. It's flying towards the field where he is. Luckily, it didn't hit him. He picked up the stone and kept it without letting anyone know. From that day onwards, Aaron had been studying the rocks and eventually became the mineralogist. He wasn't just any mineralogist but a renowned one. He always describe the Achondrites as lack of chondrules, originate on differentiated planetary bodies which has planetary bodies with a distinct core and crust, such as asteroids, planets, or moons, and were reformed from molten fragments that were flung into space as the result of another collision. Because achondrites closely resemble terrestrial rocks to the naked eye, they are less commmonly encountered as finds. The achondrites include angrites, aubrites, diogenites, eucrites, howardites, lunar meteorites,martian meteorites, primitive achondrites such as acapulcoites, brachinites, lodranites, andwinonaites, and ureilites. Tafassasset is an exceptional meteorite that has been linked to both the CR chondrites and the primitive achondrites. Because previous evidence suggests it might be a primitive achondrite from a known chondrite type, we have undertaken a study of the petrology, geochemistry, and formation history of the meteorite. Tafassasset is predominantly rich olivine yet contains abundant Fe,Ni-metal and sulfide. Other phases include high- and low-Ca pyroxene, plagioclase, chromite, and phosphate. It has a recrystallized texture, containing equigranular grains that often meet at triple junctions. There are no relict chondrules in the thin sections examined, although they have been reported previously.
