Writeup

Writeup from MB 106:

Northwest Africa 10648 (NWA 10648)

(Northwest Africa)

Purchased: 2015 Dec

Classification: Ordinary chondrite (LL3)

History: Purchased by Fabien Kuntz in December 2015 from a dealer in Agadir, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed chondrules (apparent diameter 700±400 μm, one 4.2 mm) are set in a fine grained matrix (~15 vol.%).

Geochemistry: Olivine (Fa_6.1-73.2; Cr₂O₃ in ferroan examples 0.04-0.09 wt.%, mean 0.06±0.01 wt.%, N = 6), orthopyroxene (Fs_4.2-30.3Wo_0.2-1.1, N = 3), subcalcic augite (Fs_10.0Wo_33.6), augite (Fs_6.3Wo_43.2). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.17.

Classification: Ordinary chondrite (LL3). LL designation supported by magnetic susceptibility.

Specimens: 23.35 g including one polished thin section at PSF; remainder with Kuntz.
