Writeup from MB 105:

Northwest Africa 10960 (NWA 10960)

(Northwest Africa)

Purchased: 2016 Jun

Classification: Ordinary chondrite (L4)

History: Purchased by Ben Hoefnagels in June 2016 from a dealer in Ouarzazate, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed chondrules (apparent diameter 450±300 μm) are set in a relatively coarse grained matrix containing irregularly shaped grains of altered metal, merrillite and chlorapatite. Tiny blebs of metal are prevalent in the silicate phases (rendering them very dark in thin section) and thin, glassy shock veins transect the specimen in places.

Geochemistry: Olivine (Fa24.6-24.9, N = 3), orthopyroxene (Fs20.3-20.7Wo2.2-1.5, N = 3), clinopyroxene (Fs7.2-8.1Wo45.9-44.4, N = 2).

Classification: Ordinary chondrite (L4, highly shocked).

Specimens: 177.2 g including one polished thin section at UWB; remainder with Mr. B. Hoefnagels.
