History: Purchased by Eric Twelker in April 2014 from a dealer in Erfoud, Morocco. Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, very closely packed chondrules occur in a very sparse metal-bearing matrix. Geochemistry: Olivine (Fa3.9-37.1; Cr2O3 in ferroan olivine 0.04-0.17 wt.%, N = 7), orthopyroxene (Fs2.0-20.6Wo0.5-0.8, N = 3), augite (Fs4.3Wo37.7, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.86. Classification: Ordinary chondrite (L3). L designation based on magnetic susceptibility. Specimens: 23.3 g plus one polished thin section at UWB. The remainder is held by Twelker.

History: Purchased by Blaine Reed in April 2021 from a Moroccan dealer at the Tucson Gem and Mineral Show. Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Well-delineated slightly shock-darkened chondrules containing devitrified glass are set in a relatively coarse-grained matrix containing fresh kamacite, augite, troilite, chromite and chlorapatite, but no plagioclase. Olivine in chondrules is equilibrated but low-Ca pyroxene is unequilibrated. Dark melt veins containing silicate glass, 1-10 µm olivine grains, and blebby kamacite+troilite are present. Geochemistry: Olivine (Fa24.7±1.0, range Fa24.0-26.4, N = 5), low-Ca pyroxene (Fs17.6±5.4Wo2.0±1.5, range Fs4.0-22.7Wo0.3-5.0, N = 9). Classification: Ordinary chondrite (L4, partially shock-melted). Specimens: 106.1 g including one polished thin section at PSF; remainder with Reed.
