Northwest Africa 8363 (NWA 8363)

(Northwest Africa)

Purchased: 2013 Dec

Classification: Ordinary chondrite (L, melt rock)

History: Purchased by John Higgins in December 2013 from a dealer in Guelmin, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) This specimen consists almost entirely of fine, lath-shaped silicate grains (i.e., a melt texture) with ragged and wispy grains of melted metal; hence S6. Fine-grained aggregate of lath-shaped grains of olivine, orthopyroxene, clinopyroxene sodic plagioclase, chromite, merrillite, and troilite, plus ragged shred-like grains of kamacite and primary pores. Rare objects that may be relict chondrules are present in places.

Geochemistry: Olivine (Fa24.6-25.2, N = 3), orthopyroxene (Fs19.8-20.7Wo1.2-2.5, N = 3), clinopyroxene (Fs7.3-7.7Wo44.8-44.7).

Classification: Ordinary chondrite (L melt rock).

Specimens: 29 g including one polished thick section at UWB. The remainder is held by J. Higgins.
