Physical characteristics: One small individual covered with a black shiny crust was recovered from the north-African Sahara. Petrography: The meteorite is a polymict breccia composed of lithic and mineral clasts set in a fine-grained clastic matrix. Lithic clasts are dominantly gabbroic, basaltic and impact melt up to 5 mm in size; mineral clasts include olivine, fayalite, pyroxene with very fine exsolution lamellae, and feldspar grains. Accessories are pigeonite (Fs55.3Wo13.7), Ti-chromite, ilmenite, and silica. Some melt veins and pockets are present. Geochemistry: olivine: Fa34.1±2.2 (Fa31.7-40.3, n=24) FeO/MnO mean= 100±9; fayalite: Fa92.3±3.9 (Fa83.7-97, n=26) FeO/MnO mean= 97±5; Ca-pyroxene: Fs39.1±9.5Wo32.4±9.6 (Fs29.7-55.8Wo20.3-43.3, n=33, FeO/MnO mean= 79±11.9); calcic plagioclase: An93.4±1.6 (An90.2-94.6, n=16) | ||||||||||||||||||||||||||||||
