Place/Time: 2025 in Mauretania
Mass: 1265g
History:The meteorite was purchased from a dealer in Mauritania.
Physical characteristics: Grayish rock partly covered with fusion crust..
Petrography: (A. Greshake, L. Eisgruber, MNB) Achondritic breccia composed of up to 6 mm sized orthopyroxene and up to 4 mm sized plagioclase crystals (about 15 vol%) in related fine-grained clastic matrix. Most low-Ca pyroxenes contain fine lamellar and blebby augite exsolutions. Contains several up to 4 mm sized black impact melt clasts. Minor phases include chromite, troilite,and Ni-free metallic iron.
Geochemistry: low-Ca pyroxene: Fs33.3±0.3Wo3.0±0.8 (Fs32.9-33.8Wo2.0-4.1, FeO/MnO=28-32, n=7); Ca-pyroxene: Fs13.1±0.7Wo42.7±0.8 (Fs12.3-14.0Wo41.6-43.6, FeO/MnO=21-25, n=5); calcic plagioclase: An85.2±0.7 (An84.2-86.2, n=7)
