Writeup from MB 106:

Northwest Africa 11076 (NWA 11076)

(Northwest Africa)

Purchased: 2016 Nov

Classification: Ordinary chondrite (LL(L)3)

History: Purchased by Darryl Pitt in November 2016 from a dealer in Mauritania.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely-packed, well-formed chondrules (apparent diameter 500±400 μm) are set in a fine grained matrix containing altered metal.

Geochemistry: Olivine (Fa2.6-76.8, Cr2O3 in ferroan examples 0.05-0.14 wt.%, mean 0.09±0.03 wt.%, N = 7), orthopyroxene (Fs1.0-17.0Wo0.9-1.3, N = 3), diopside (Fs0.9Wo35.8), subcalcic augite (Fs17.4Wo29.5). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.22.

Classification: Ordinary chondrite (LL(L)3).

Specimens: 11.7 g including one polished thin section at UWB; remainder with DPitt.
