Location: Northwest Africa, location unknown. Purchased in 2022.

Found: Purchased in October 2022.

Classification: Carbonaceous chondrite (CO3).

Description: History: Purchased by Eric Twelker in October 2022 from a dealer in Guelmim, Morocco. Petrography: (A. Irving, UWS , and J. Boesenberg, BrownU ) Well-defined small chondrules (apparent diameter 270±240 µm, N = 265) containing devitrified glass together with mineral fragments and some small CAI are set in a fine grained matrix (~20 vol.%, reddish-brown in thin section) containing kamacite, troilite and minor Cr-magnetite. Calcic plagioclase is present in some chondrules and some chondrules contain abundant inclusions of metal and troilite. Minerals in CAI include gehlenite, diopside and forsterite. Geochemistry : Olivine (Fa _21.7±18.6 , range Fa _0.9-50.4 , N = 13; Cr ₂ O ₃ in ferroan olivine 0.04-0.28 wt.%, mean 0.08±0.07 wt.%, N = 14), low-Ca pyroxene (Fs _14.9±15.9 Wo _1.9±1.5 , range Fs _1.0-45.2 Wo _0.5-4.9 , N = 10), subcalcic augite (Fs _3.7±2.8 Wo _33.4±4.0 , range Fs _1.8-5.7 Wo _30.6-36.3 , N = 2), plagioclase (An _74.9-75.2 Or _0.8 , N = 2), magnetite (Cr ₂ O ₃ 3.8 wt.%).

Classification : Carbonaceous chondrite (CO3).
