Adrar 014 27º07.8117’N, 01º02.0238’E Adrar, Algeria Find: 2023 Classification: Lunar meteorite (feldspathic breccia) History: The samples were found in desert N of Timokten, Algeria, in 2023. Shun-Chung Yang purchased the samples from Ali Mftah in 2023. Physical characteristics: Stone has a light greenish-gray exterior and is irregular shaped. Interior has a light greenish-gray brecciated texture. Petrography: Description and classification (A. Love, App) Sample shows a melt breccia texture composed of sparsely-distributed up to 2.5 mm-sized angular to subrounded lithic and mineral clasts set within a melt matrix host with subophitic texture composed of weakly zoned olivine, pyroxene and plagioclase with an average grain size of 97 µm, n=14. Lithic clasts are anorthosites and troctolites. Mineral clasts dominated by plagioclase. Sample is transected by schlieren-textured devitrified glassy melt veins. Additional minerals are: rare ilmenite, pentlandite, chromite, spinel, troilite and barite. Geochemistry: (A. Love, App) Clasts: olivine (Fa22.8±6.8, Fe/Mn=78.6±4.2, n=7); low Ca-pyroxene (Fs16.4Wo2.4, Fe/Mn=49.0, n=1). host: olivine (Fa22.8±2.1, Fe/Mn=85.7±5.0, n=11); pigeonite (Fs22.6±3.0Wo13.1±2.9, Fe/Mn= 52.8±1.8, n=6); high Ca-pyroxene (Fs9.9±4.1Wo38.3±8.9, Fe/Mn=36.0±6.5 n=4); plagioclase (An97.7±0.2Or0.0, n=10). Classification: Lunar achondrite (feldspathic melt breccia A-S3 W3) Based on textures, and mineral chemistry, sample is a feldspathic melt breccia. Specimens: Shun-Chung Yang (S-R meteorites) holds the main mass. A polished thin section and a broken individual weighing 22.66 g are on deposit at App. | ||||||||||||||||||||||||||||||||||
