Pallasite meteorites like the Imilac formed in the asteroid belt, located between Mars and Jupiter. They are made up of minerals and metal, remnant materials from the first few million years of the solar system.
They formed inside asteroids at a time when planets were only just coming together.
So are all of these Imilac specimens believed to be fragments of one single object that exploded before reaching the surface? If so, why not call them Imilac meteorites (plural) instead of talking about "Imilac meteorite" as a name for a material that is uncountable?
