(Northwest Africa)

Purchased: 2023 Feb

Classification: HED achondrite (Diogenite, olivine)

Petrography: (K. Metzler, IfP) Achondritic breccia consisting of pyroxenite clasts with sizes up to several mm, embedded in small amounts of fine-grained related debris. Considerable amounts of olivine and plagioclase fragments are present. Accessories are Cr-spinel, F-apatite, and Fe-Ni metal.

Geochemistry: Mineral compositions and geochemistry: Pyroxene composition: Fs_24.8±0.9Wo_1.8±0.2(Fs_23.6-26.2Wo_1.5-2-2); mean Fe/Mn (at.): 33.9; n=14. Olivine composition: Fa_31.6±0.7(Fa_30.4-33.3); Fe/Mn (at.): 52.9; n=15. Plagioclase composition: An_92.6±2.0Or_0.1±0.2(An_88.6-95.9Or_0.0-0.5); n=13.

Classification: Brecciated olivine-bearing diogenite, based on texture and mineral chemistry.
