(Northwest Africa)

Purchased: 2015 Sep

Classification: HED achondrite (Eucrite)

History: Purchased by Aras Jonikas in September 2015 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of diabasic eucrite clasts and related crystalline debris. Exsolved pyroxene is orange in thin section and calcic plagioclase is polycrystalline. Accessory minerals include silica polymorph, ilmenite, Ti-chromite and troilite, plus minor secondary calcite and barite.

Geochemistry: Orthopyroxene host (Fs59.9-61.3Wo4.5-2.7, FeO/MnO = 30-34, N = 3), clinopyroxene exsolution lamellae (Fs28.1-28.8Wo42.3-41.7, FeO/MnO = 28-29, N = 3).

Classification: Eucrite (diabasic breccia, shocked).
