Physical characteristics: Many grayish fragments without fusion crust. Petrography: The meteorite is a polymict breccia composed of lithic and mineral clasts set into a fine-grained clastic matrix. Lithic clasts are basaltic and dark impact melt clast up to 2 mm in size. Main minerals are up to 1 mm sized orthopyroxene with diogenitic composition (about 25%), compositionally zoned low-Ca pyroxene, exsolved pyroxene and calcic plagioclase. Minor phases include silica, chromite, and FeS. No metallic iron detected. Geochemistry: low-Ca pyroxene: Fs60.3±4.0Wo3.4±1.0 (Fs54.4-63.8Wo2.3-5.1, FeO/MnO=30-32, n=10); augite exsolution lamellae: Fs20.9±0.2Wo42.2±0.2 (Fs20.4-21.1Wo41.8-42.6, FeO/MnO=21-24, n=10); diogenetic pyroxene: Fs26.5±0.2Wo2.4±0.1 (Fs26.1-26.8Wo2.2-2.6, FeO/MnO=26-28, n=10); zoned pyroxene: Fs45.0±11.0Wo14.5±8.6 (Fs34.4-64.1Wo5.8-25.2, FeO/MnO=26-32, n=10); calcic plagioclase: An94.0±1.5 (An91.5-96.0, n=10) | ||||||||||||||||||||||||||||
