aubrite An enstatite pyroxene-rich, achondritic meteorite that is poor in calcium. The enstatite, which often forms large crystals, has very low FeO/(FeO + MgO) ratios, Aubrites may contain up to 1.2% elemental silicon included within rare Fe–Ni grains, and appear to have close affinities with the similarly highly reduced enstatite chondrites.
