History: Three partially crusted stones with a weight of 201 g were purchased in Erfoud, Morocco, in 2006.

Petrography: (T. Bunch and J. Wittke, NAU ): A basaltic shergottite that contains 54 vol% Ca-pyroxene (pigeonite and augite), 41 vol% plagioclase (maskelynite) and minor ulvöspinel, ilmenite, merrillite, chlorapatite, pyrrhotite, and K-Si-rich, late stage glasses. Pyroxene shows mottled compositional zoning. Dark, shock pocket glasses and veins are also present. A few melt inclusions of K-Si-rich glass, phosphates, ferroan pigeonite, and ilmenite were found in ulvöspinel.

Geochemistry: Pigeonite Fs37.4-53.8Wo10.8-15.8 (FeO/MnO = 34); augite Fs27.8-40.6Wo33.4-36.0; maskelynite An54.7Or1.6. Oxygen isotopes (D. Rumble, CIW ): Replicate analyses of acid-washed whole rock samples by laser fluorination gave, respectively δ18O = 4.65, 4.59, 4.45, 4.78, δ17O = 2.73, 2.67, 2.58, 2.80, Δ17O = 0.280, 0.260, 0.240, 0.284 (all permil). Bulk composition (ICPMS, C.
