Writeup from MB 105:

Northwest Africa 10502 (NWA 10502)

(Northwest Africa)

Purchased: 2015 May

Classification: Ordinary chondrite (LL3)

History: Purchased by Pierre-Marie Pelé in May 2015 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, fairly closely packed chondrules (apparent diameter 1.3±0.8 mm) are set in a finer matrix.

Geochemistry: Olivine (Fa2.1-38.3, Cr2O3 in ferroan olivine 0.05-0.07 wt.%, mean 0.06±0.01 wt.%, N = 8), orthopyroxene (Fs3.2-24.3Wo0.4-2.1, N = 3), clinopyroxene (Fs16.5-16.7Wo30.4-33.8, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.02.

Classification: Ordinary chondrite (LL3).

Specimens: 26.28 g including one polished thin section at PSF; remainder with Mr. P. Pelé.
