Writeup from MB 105:
Northwest Africa 10870 (NWA 10870) (Northwest Africa) Purchased: June 2016 Classification: Ureilite History: The meteorite was purchased in 2016 from a meteorite dealer at the mineral fair in St.Marie aux mines, France. Petrography: The rock shows a fine-grained, equigranular texture of olivine and orthopyroxene with frequent triple junctions at adjoining mineral grains. Olivine is compositionally homogeneous and orthopyroxene show slight zoning. Although intensely recrystallized the outlines of the original minerals are still visible. Also several characteristic reduced rims are preserved at olivine-carbon contacts. The sample contains lamellar intergrowths of daubreelite and troilite. Geochemistry: reduced rims in olivine: Fa2.6-5.7; Cr2O3 in ol: ~0.5 wt% Classification: Ureilite, melt rock. | ||||||||||||||||||||||||||||||
