Salek Mrabih purchased the sample from a meteorite dealer in June 2023. Physical characteristics: Stones have a rounded shape and lack fusion crust. The cut face is light gray in color and shows a brecciated texture. Petrography: Description and classification (A. Love, App) Sample shows brecciated texture dominated by anhedral exsolved pyroxene and plagioclase fragments. Average grainsize of plagioclase felspar is 65.6µm, n=20. Additional minerals are: a silica polymorph, apatite, Cr-bearing ilmenite, chromite and troilite. Geochemistry: (A. Love, App) low Ca-pyroxene (Fs65.3±1.1Wo2.8±1.2, Fe/Mn=31.1±0.5 n=12); high Ca-pyroxene (Fs31.0±1.5Wo41.0±1.5, Fe/Mn=31.3±1.2 n=12); plagioclase (An92.1_1.1Or0.2±0.1, n=12). Classification: HED achondrite (eucrite breccia M-S2 low weathering) Based on textures and mineral compositions, sample is a equilibrated basaltic eucrite breccia with M-S2 and low weathering. Specimens: Salek Mrabih (Dominion meteorites) holds the main masses. A polished thin section and 7 small individuals weighing 20.2 g are on Deposit at App. Data from: MB112 Table 0 Line 0: Place of purchase: Morocco Date: P 2023 Mass (g): 3200 Pieces: many Class: Eucrite Shock stage: M-S2 Weathering grade: low Ferrosilite (mol%): 65.3±1.1; 31.0±1.5 Wollastonite (mol%): 2.8.4±1.2; 41.0±1.5 Classifier: A.
