Mass: 916g
History: Purchased by M. Cimala from a Moroccan dealer in February 2013.
Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, mostly medium-sized (some larger) and well-formed chondrules (0.7-2.8 mm, mean diameter 1.7 mm). Minerals are olivine, orthopyroxene, subcalcic augite, augite, sodic plagioclase, troilite, chromite and altered kamacite.
Geochemistry: Olivine (Fa0.6-51.8; Cr2O3 in ferroan olivine = 0.05-0.13 wt.%, mean 0.08 wt.%, s.d. = 0.03 wt.%, N = 8), orthopyroxene (Fs0.7-21.3Wo0.5-0.8, N = 3), subcalcic augite (Fs20.1Wo26.7), augite (Fs13.8Wo37.8).
