Petrography: Carbonaceous chondrite with large CAIs <0.8 cm, AOAs, and obvious chondrules on the cut surface. CAIs are predominantly spinel with some fassaite and grossular. There is a sharp contact between the clast and host lithology. The clast silicates are mostly olivine. Rare magnetite is identified. Geochemistry: Olivine Fa1.1-30.1, mean Fa6.9±7.6 (n=32). Pyroxene Fs0.8-1.7Wo0.7-9.7, mean Fs1.1±0.3Wo1.8±2.5 (n=13). Clast olivine Fa0.6-9.9, mean 4.3±3.0 (n=15). Plagioclase An84.2-97.4Or0.0-0.1, mean An94.3±5.7Or0.0±<0.1 (n=5). Classification: Chondrule size, CAI size and composition suggest CV3 classification is appropriate. Not enough clast material is available to accurately determine if it belongs to a different meteorite type or not.
