History: The meteorite was purchased from a dealer in Algeria. Physical characteristics: Many brownish fragments with some fusion crust. Petrography: Protogranular aggregate predominantly composed of typically 150 to 200 µm sized calcic olivine, Al-Ti-augite, pleonaste spinel, and less abundant almost pure anorthite. Some cluster of more coarse-grained up to 500 µm sized minerals are present. Triple junctions between adjoning phases are frequently encountered. Minor phases include troilite and kamacite. Geochemistry: olivine: Fa38.4±0.1Ln1.7±0.1 (Fa38.2-38.6Ln1.5-1.9, FeO/MnO=72-85, CaO: 1.2±0.1, n=7); Al-Ti-augite: Fs10.1±0.2Wo52.6±0.2 (Fs9.8-10.5Wo52.3-52.8, FeO/MnO=47-121, Al2O3: 9.2±0.3 wt.%, TiO2: 1.1±0.1 wt.%, n=7); anorthite: An98.7-99.3Ab0.7-1.2, n=7, pleonaste spinel: Fe/(Mg+Fe): 0.52±0.01, Al2O3: 58.3±0.4 wt%, n=7 Specimens: Mario Suppes holds 115 g and and Polandmet - Marcin Cimala holds 55 g.
