Writeup from MB 99:

Northwest Africa 2680 (NWA 2680)

Morocco

Purchased: 2005

Classification: Iron meteorite (IAB-sLH)

Petrography: Silicate-rich iron with 60-65 vol% metal which mainly consists of small domains each with a differently oriented octahedral pattern; typical size 0.6 to 1.0 cm. Within the domains, kamacite forms narrow lamellae with high (10-20) aspect ratios. Widest bands are ~0.15 mm, thus the metal structure is Off. Most domains are surrounded by swathing kamacite 0.2-0.3 mm thick. Angular silicate blocks are abundant, comprising 10-15 vol%; largest clast 5x1.5 mm. FeS also abundant, ~10 vol%. Schreibersite not confirmed. Based on structure, possibly paired with NWA 4024 and 5980 that are described as winonaites.

Geochemistry: Co (mg/g) 5.36, Ni (mg/g) 136.6, Ga (µg/g) 24.3, Ge (µg/g) <140, As (µg/g) 19.4, Ir (µg/g) 2.04, Au (µg/g) 1.73.
