Northwest Africa 10286 (NWA 10286)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (H3-5)

History: Purchased by an anonymous collector from a dealer at the Munich Show in 2005 and subsequently donated to the PSF.

Petrography: (A. Irving and S. Kuehner, UWS) Predominantly an unequilibrated specimen consisting of well-formed chondrules (apparent diameter up to 1.2 mm) in a finer grained matrix rich in stained metal, but one type 5 recrystallized clast is present in the studied thin section.

Geochemistry: Olivine (Fa0.7-48.5, Cr2O3 in ferroan examples 0.06-0.53 wt.%, mean 0.23 wt.%, N = 7), orthopyroxene (Fs3.8-38.4Wo0.2-1.9, N = 3), augite (Fs5.6-7.9Wo47.3-46.0, N = 2).

Classification: Ordinary chondrite (H3-5 breccia).

Specimens: The entire specimen plus one polished thin section made from it are reposited at PSF.
