This meteorite is largely comprised of enstatite, and it is presumed to be a partial melt derived from an E or EH-chondrite precursor. There’s quite a bit of literature on this meteorite, most of it related to the E-chondrite parent body and the timeframe of its differentiation. The volatilization and deposition of metal along silicate grain boundaries gives this meteorite a spectacular, unique appearance.
