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 Eric Twelker in March 2009 from a dealer in Pohlheim, Germany. Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, fairly closely packed chondrules occur in a finer grained, metal-bearing matrix. Geochemistry: Olivine (Fa0.4-92.1; Cr2O3 in ferroan olivine 0.11-0.61 wt.%, mean 0.23 wt.%, sd 0.12 wt.%, N = 16), orthopyroxene (Fs0.5-19.1Wo4.3-5.5, N = 3), subcalcic augite (Fs19.3Wo25.1, N = 1), augite (Fs7.4Wo38.7, N = 1). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.84. Classification: Ordinary chondrite (L3). L group designation based on magnetic susceptibility. The very wide range in Fa content of olivine, along with the mean value and standard deviation for Cr2O3 content of ferroan olivines, indicate that this unequilibrated specimen is of a subtype

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.
