Northwest Africa 11069 (NWA 11069)

(Northwest Africa)

Purchased: 2016 Sep

Classification: Ordinary chondrite (LL(L)3)

History: Purchased by Fred Olsen in September 2016 from a Moroccan dealer at the Denver Show.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely packed, well-formed chondrules (apparent diameter 500±400 μm, one 4 mm) are set in a fine-grained matrix containing altered metal.

Geochemistry: Olivine (Fa0.4-49.7, Cr2O3 in ferroan examples 0.02-0.44 wt.%, mean 0.16±0.14 wt.%, N = 8), orthopyroxene (Fs1.5-21.8Wo0.4-1.0, N = 3), subcalcic augite (Fs19.4-22.7Wo23.0-29.6, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.20.

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

Specimens: 21.0 g including one polished thin section at UWB; remainder with Mr. F. Olsen.
