History: Purchased by Mbark Arjdal in July 2018 from an Algerian dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of closely-packed eucrite clasts in a very sparse matrix (~2 vol.%).

Geochemistry: Pigeonite (Fs51.4-53.0Wo14.0-11.0, FeO/MnO = 32-35, N = 3), anorthite (An90.6-90.8Or0.4, N = 2).

Specimens: 7.3 g including one polished thin section at UWB; remainder with Mr. M. Arjdal.
