Writeup from MB 106:

Northwest Africa 8134 (NWA 8134)

(Northwest Africa)

Purchased: 2013 Oct

Classification: Ordinary chondrite (H4)

History: Purchased by Adam Aaronson in Temara, Morocco in October 2013.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, relatively small chondrules (apparent diameter predominantly 350±250 μm, but some chondrules are in the 1.5-2.2 mm range) in a dark reddish-brown matrix containing altered metal. Glass is present in some chondrules. Minerals are olivine, orthopyroxene, augite, sodic plagioclase, altered kamacite, chromite and troilite.

Geochemistry: Olivine (Fa16.9-17.3, N = 3), orthopyroxene (Fs14.5-14.6Wo0.4-2.7, cores Fs4.6.Wo0.4; N = 3), augite (Fs6.3-13.5Wo38.8-43.3, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg)=4.88.

Classification: Ordinary chondrite (H4).

Specimens: 25.4 g including one polished thin section at UWB. The remainder is held by Aaronson.
