Northwest Africa 11056 (NWA 11056)

(Northwest Africa)

Purchased: 2016 Oct

Classification: Ordinary chondrite (LL3)

History: Purchased by John Higgins in October 2016 from a dealer in Nouakchott, Mauritania.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely packed, well-formed chondrules (apparent diameter 500±300 μm) are set in a sparse, fine-grained matrix containing altered metal.

Geochemistry: Olivine (Fa0.4-47.3, Cr2O3 in ferroan examples 0.05-0.11 wt.%, mean 0.08±0.03 wt.%, N = 7), orthopyroxene (Fs2.5-22.7Wo0.2-2.2, N = 3), pigeonite (Fs31.0Wo16.8), augite (Fs11.2Wo45.3). Magnetic susceptibility log χ (× 10-9 m3/kg) = 3.73.

Classification: Ordinary chondrite (LL3).

Specimens: 23.95 g including one polished thin section at UWB; remainder with Mr. J. Higgins.
