Writeup from MB 105:
Northwest Africa 10462 (NWA 10462) (Northwest Africa) Purchased: Dec 2014 Classification: Ordinary chondrite (LL6, anomalous) History: Four identical appearing specimens were purchased by Zohir Fettouh in December 2014 in Guelmim from a local meteorite hunter who found them near Bir Anzarane, Morocco. Type specimen was provided by Steve Arnold. Physical characteristics: Four stones with weathered exterior; saw cuts shows a gray fine-grained interior with some mild brecciation. Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows some distinct chondrules, plagioclase up to 100 μm. No kamacite, but FeNiS phase + taenite, and chromite, iron sulfide and iron-nickel sulfide were observed. Geochemistry: (C. Agee and N. Muttik, UNM) Olivine Fa33.8±0.4, Fe/Mn=70±2, n=6; low-Ca pyroxene Fs27.0±0.3Wo1.8±0.2, Fe/Mn=41±2, n=6. Classification: Ordinary chondrite (LL6-an). Anomalous based on olivine Fa-content outside the range for LL-chondrites (Fa>33), similar to NWA 6588 (LL6-an with Fa33.3). Specimens: 21 g including a probe mount on deposit at UNM, Zohir Fettouh holds the main mass. | ||||||||||||||||||||||||||||||
