From Meteoritical Bulletin :

History and physical characteristics: A 2250 g dark brown, heavily stained stone was found in Algeria in 2005 and sold in Rissani, Morocco in 2005.
Petrography: (T. Bunch and J. Wittke, NAU) contains a few shocked dark clasts and several centimeter-sized cream-colored igneous-textured (idiomorphic granular) clasts. These irregular-shaped, olivine pyroxenite clasts contain (vol %): orthopyroxene/clinopyroxene, 56; olivine, 33; mesostasis, 5; diopside, FeS, ilmenite, chromite, and metal, 4. Both clinoenstatite (polysynthetically twinned) and orthopyroxenite are present, crystallographic orientation within the section, notwithstanding. For compositional considerations, they are treated the same.
Mineral compositions: Chondritic host examples: POP chondrule olivine cores (Fa9–17, FeO/MnO = 47-55 g/g), rims (Fa26.1–35.8, FeO/MnO = 69-90 g/g). Matrix olivine, Fs15–35.6; FeO/MnO avg. = 53 g/g; Cr2O3 = 0.05–0.45%, mean = 0.12 wt. %. Olivine pyroxenite clasts: orthopyroxene, Fs0.2-0.7Wo0.8 (N=27); olivine, Fa0.7–4.7, FeO/MnO = 15-19 g/g (N=13); diopside, Fs1Wo42; mesostasis plagioclase, An96.9; ilmenite, MgO = 5.4 wt. %; chromite, Cr/(Cr+Al) = 0.82; taenite, Ni = 37.8 wt. %.
Classification: Ordinary chondrite (LL3.2). Subtype designation based on olivine heterogeneity and olivine Cr2O3 contents.
