(Northwest Africa)

Purchased: 2013 July

Classification: HED achondrite (Howardite)

Petrography: (A. Greshake, MNB) The small grayish colored individuals contain abundant diogenetic and less abundant coarse-grained basaltic eucrite clasts set into a fine-grained clastic matrix. Some dark melt clasts were encountered. Basaltic eucrite clasts are composed of exsolved pyroxene and calcic plagioclase. Accessory minerals include silica polymorphs, pyrrhotite, and chromite.

Geochemistry: Low-Ca pyroxene: Fs20.7-56.7Wo1.7-5.8; FeO/MnO=24-32; augite: Fs23-29.2Wo39.6-41.7; FeO/MnO=27-32; calcic plagioclase: An68-87.7
