Writeup from MB 104:

Northwest Africa 8788 (NWA 8788)

(Northwest Africa)

Purchased: 2014 Jul

Classification: Ordinary chondrite (LL3)

History: Purchased by Fabien Kuntz in July 2014 from a dealer in Foum El Hisn, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, well-formed, medium-sized chondrules (1.1±0.7 mm) occur in a matrix containing stained metal.

Geochemistry: Olivine (Fa1.7-60.9; Cr2O3 in ferroan examples 0.09-0.81 wt.%, mean 0.19±0.20 wt.%, N = 15), orthopyroxene (Fs4.1-14.9Wo0.3-2.1, N = 3), pigeonite (Fs34.3Wo5.5), subcalcic augite (Fs4.5-5.1Wo35.7-37.7, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 3.37.

Classification: Ordinary chondrite (LL3). LL group designation based on magnetic susceptibility.

Specimens: 5.29 g including one polished thin section at PSF; main mass with Kuntz.
