Northwest Africa 15372 (NWA 15372) Northwest Africa Purchased: 2022 Classification: Primitive achondrite (Acapulcoite) History: Purchased by Mark Lyon from a Moroccan meteorite dealer in 2022. Physical characteristics: Single stone mostly covered with smooth, dark-colored fusion crust. There are also patches of orange-brown colored patina. Petrography: (A. Ross and C. Agee, UNM) Recrystallized granoblastic texture with triple junctions between olivine, pyroxenes, and plagioclase. Most silicate grains are in the size range 200-300 microns. Kamacite makes up approximately 5% of this meteorite. Troilite and chromite are ubiquitous minor phases. Vesicular fusion crust is approximately 500 microns thick. Geochemistry: (A. Ross, UNM) Olivine Fa11.1±0.1, Fe/Mn=21±1, n=6; low-Ca pyroxene Fs10.2±0.2Wo1.6±0.3, Fe/Mn=13±1, n=3; high-Ca pyroxene Fs4.2±0.1Wo44.8±0.9, Fe/Mn=9±1, n=3; plagioclase An12.2±0.1Ab82.3±0.1, n=4; fusion crust SiO2=43.2±1.0, TiO2=0.16±0.02, Cr2O3=0.29±0.01, Al2O3=2.6±0.1, FeO=22.4±1.8, MnO=0.39±0.02, MgO=25.0±0.9, CaO=3.3±0.3, NiO=0.40±0.25, Na2O=0.88±0.10, K2O=0.11±0.01 (all wt%), n=3.
