Physical characteristics: Single light-gray stone with fusion crust. Cut surface show fine-grained light-gray interior.

Petrography: (J. Gattacceca, CEREGE) Brecciated igneous rock with grain size ~400 µm. Main minerals are pyroxene (exsolved) and plagioclase (not maskelynite). This rock contains both eucrite material with subophitic texture, and diogenite material (more than 10 vol%). Accessory minerals: sulfide, chromite, ilmenite, kamacite, silica polymorph.

Geochemistry: Diogenitic low-Ca pyroxene Fs25.9Wo3.1 (n=2). Eucritic low-Ca pyroxene Fs34.8Wo3.1 (n=1), Fs57.1±1.1Wo7.9±2.0 (n=3). Ca-pyroxene Fs30.1Wo39.4 (n=2). Pyroxene overall FeO/MnO 29.8±1.1 (n=8). Plagioclase An90.5Ab9.3Or0.1 (n=2). Chromite Cr# = 0.82
