Northwest Africa 7319 (NWA 7319)

(Northwest Africa)

Purchased: 2012 Apr

Classification: Ordinary chondrite (L5, melt breccia)

History: Purchased by Greg Hupé in April 2012 from a dealer in Erfoud, Morocco.

Physical characteristics: Fresh interior slices show dispersed clasts of chondrule-bearing material within more abundant fine-grained, black material containing ellipsoidal metal+sulfide grains.

Petrography: Some regions contain sparse chondrules with moderate amounts of metal, but the predominant lithology is composed of very fine grained olivine, pyroxene and rounded grains of intergrown kamacite+troilite.

Geochemistry: Olivine (Fa23.7-23.8), orthopyroxene (Fs19.7-20.6Wo2.8-1.9).

Classification: Ordinary chondrite (L5-melt breccia).
