Writeup from MB 103:

Northwest Africa 8015 (NWA 8015)

(Northwest Africa)

Purchased: 2012 Jun

Classification: Ordinary chondrite (L5, melt breccia)

History: Purchased by F. Kuntz in June 2013 at the Ensisheim Show.

Physical characteristics: The specimen (1513 g) is composed of rounded, pale orange clasts in a black, very fine-grained matrix containing wispy grains of fresh metal.

Petrography: (A. Irving and S. Kuehner, UWS) This is a typical L5 melt breccia composed of about equal proportions of L5 chondrite clasts (S2, W1) and quenched (impact) melted matrix of very fine grained silicates with irregular, shred-like grains of metal.

Geochemistry: Olivine (Fa_24.7-25.2), orthopyroxene (Fs_20.6-20.7Wo_1.3-1.6), augite (Fs_7.6-7.9Wo_43.8-43.3).

Classification: Ordinary chondrite (L5 melt breccia).

Specimens: 20.1 g including one polished thick section at UWB. The remainder is held by Kuntz.
