Physical characteristics: A single 47.3 g stone lacking fusion crust with visible whitish clasts. Petrography: (A. Irving and S. Kuehner, UWS) Breccia consisting of numerous mineral fragments in a finer-grained matrix. Minerals are anorthite, olivine, unexsolved pigeonite, subcalcic augite, exsolved pigeonite, fayalite, silica polymorph, ilmenite and rare kamacite. Geochemistry: Olivine (Fa31.0-48.4, FeO/MnO = 80-97), low-Ca pyroxene (Fs58.9Wo4.7, FeO/MnO = 59), subcalcic augite (Fs11.3Wo26.9, FeO/MnO = 37), orthopyroxene host (Fs53.4Wo4.0, FeO/MnO = 53), clinopyroxene exsolution lamellae (Fs27.7Wo39.8, FeO/MnO = 52). Bulk composition (R. Korotev, WUSL): INAA of subsamples gave mean abundances (in wt.%) FeO 4.4, Na2O 0.32, and (in ppm) Sc 7.9, La 1.8, Sm 0.77, Eu 0.76, Yb 0.59, Th 0.2.
