Classification: Chondrite L3.8 S1/W2
Time/Place: 2004 in Morocco
Mass: 680g

Petrography: (A. Irving and S. Kuehner, UWS) Closely-packed, medium-sized (apparent diameter 600±200 μm), well-formed chondrules. Minerals are olivine, orthopyroxene, subcalcic augite, sodic plagioclase, altered kamacite, troilite, chromite and taenite.
Geochemistry: Olivine (Fa15.8-25.5, N = 5; Cr2O3 content of ferroan olivine <0.02 wt.%), orthopyroxene (Fs11.9-35.4Wo0.4-4.3, N = 3), subcalcic augite (Fs11.0-26.6Wo34.8-27.0, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.65.
Classification: Ordinary chondrite (L3). Subtype estimated to be L3.8 based on the limited range in fayalite content of olivine and paucity of Cr2O3 in ferroan olivine (Grossman and Brearley, 2005).
