Classification: Diogenite S-low / W-moderate
Place/Time: September 2015 in Ouarzazate, Morocco
History: Purchased by Marcin Cimala in September 2015 from a dealer in Ouarzazate, Morocco.
Petrography: (A. Irving, UWS) Protogranular aggregate of predominantly orthopyroxene with ~5 vol.% olivine, accessory chromite, kamacite and troilite, plus rare calcic plagioclase. Cataclastic textures are absent. Secondary calcite occurs in small patches and along grain boundaries.
Geochemistry: (P. Carpenter, WUSL) Orthopyroxene (Fs24.7-24.8Wo3.7-3.8, FeO/MnO = 29-30, N = 3), olivine (Fa29.7-29.9, FeO/MnO = 48-50, N = 2).
Classification: Diogenite (protogranular, olivine-bearing).
