Writeup from MB 104:
Northwest Africa 10043 (NWA 10043) (Northwest Africa) Purchased: January 2015 Classification: Primitive achondrite (Lodranite) History: Purchased in New York City from a Moroccan dealer. Physical characteristics: One piece. A saw cut shows a mosaic of dark gray grains, some of which are as large as 1 cm. There are a few scattered, fine-grained, opaque minerals present. Petrography: (C. Agee, UNM) This lodranite consists of large poikilitic augite host crystals up to 1000 μm containing smaller olivines (~400 μm) and a few percent low-Ca pyroxene. Accessory phases include metal, oxidized metal, chromite, troilite, and a phosphate; no plagioclase was found. Geochemistry: (C. Agee and N. Muttik, UNM) Augite Fs7.6±0.3Wo42.5±0.7, Fe/Mn=16±1, Cr2O3=1.16±0.05, n=10; low-Ca pyroxene Fs16.5±0.9Wo2.4±0.0, Fe/Mn=20±1, n=2; olivine Fa14.5±0.2, Fe/Mn=27±1, n=13. Classification: Lodranite, not an acapulcoite based on coarse grain size and absence of plagioclase. Specimens: 20.6 g including a probe mount on deposit at UNM, DPitt holds the main mass. | ||||||||||||||||||||||||||||||
