Writeup from MB 104:

Northwest Africa 10306 (NWA 10306)

(Northwest Africa)

Purchased: 2015 May

Classification: Ordinary chondrite (LL3)

History: Purchased by Fabien Kuntz in May 2015 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, well-formed chondrules (apparent diameter 0.4-3.8 mm) occur in a finer-grained matrix (~10 vol.%).

Geochemistry: Olivine (Fa0.4-45.3, Cr2O3 in ferroan examples 0.02-0.19 wt.%, N = 7), orthopyroxene (Fs0.8-29.7Wo0.6-1.2, N = 3), augite (Fs5.2Wo38.8, subcalcic augite (Fs12.0Wo29.3). Magnetic susceptibility log χ = 4.15 (χ in 10-9 m3/kg).

Classification: Ordinary chondrite (LL3).

Specimens: 22.83 g including one polished thin section at PSF; remainder with Kuntz.
