Resumen:
The mineral occurs in the D?Orbigny angrite, a 16.5 kg meteorite found in July 1979 in Argentina. The polished angrite slab sample ca 1.5 x 1.5 x 0.3 cm in size used for the present study was kindly loaned by the Naturhistorisches Museum Wien, Austria (inventory number: Section D´Orbigny C-N1172-NH Wien). Detailed petrographic descriptions of the D?Orbigny angrite are available (Mittlefehldt et al., 2002; Kurat et al., 2004; Varela et al., 2003). See Authors? Remarks. Associated minerals are olivine intergrowths with Ca-rich fayalite (Ca ~20 mol%) + kirschsteinite (Ca ~40 mol%), Fe sulfides, ulvöspinel, Na-bearing anorthite, whitlockite and Al-bearing hedenbergite (Figure 1a, b) as multiple phase pockets sitting at grain triple junctions of olivine (with rims of Fe/Ca-rich olivine overgrowths) + augite (with rims of hedenbergite) aggregates.
