Resumen:
Introduction: D’Orbigny is the sixth and by far the largest angrite known. It is peculiar with respect to three features: the abundance of hollow shells, the abundant presence of glasses and the open druses with perfectly crystallized augites of prismatic habit [1-2]. Here we report on the distribution of Fe2+ among the non-equivalent sites in the druse pyroxenes of the D’Orbigny meteorite as determined by Mössbauer spectroscopy.
