Northwest Africa 7267 (NWA 7267)

(Northwest Africa)

Purchased: 2012 Feb

Classification: Ordinary chondrite (L, melt breccia)

History: Purchased by Greg Hupé in 2012 February from a Moroccan dealer at the Tucson Mineral Show.

Petrography: Fresh breccia composed of L4 to L5 chondrite clasts, medium-sized chondrule fragments and related crystal debris in a sparse metal-rich matrix. The interstitial metal forms anastomozing and cuspate zones between the chondrite clasts, which themselves contain moderate amounts of stained kamacite and troilite.

Geochemistry: Olivine (Fa24.0-24.5), orthopyroxene (Fs19.9-20.2Wo1.5-2.0; sparse magnesian cores Fs12.5Wo3.0), clinopyroxene (Fs9.0-10.7Wo43.8-43.5).

Classification: Ordinary chondrite (L-melt breccia).
