Northwest Africa 11672 (NWA 11672)

(Northwest Africa)

Purchased: 2017 Jun

Classification: Ordinary chondrite (L3)

History: Purchased by Gary Fujihara in June 2017 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, well-formed, unequilibrated chondrules (apparent diameter 620±340 µm, N = 18) are set in a recrystallized matrix containing slightly stained kamacite.

Geochemistry: Olivine (Fa1.8-64.0, Cr2O3 in ferroan examples 0.02-0.84 wt.%, mean 0.19±0.33 wt.%, N = 8), orthopyroxene (Fs3.3-18.8Wo0.2-2.0, N = 3), augite (Fs8.7-11.8Wo41.3-36.7, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.73.

Classification: Ordinary chondrite (L3).

Specimens: 21.8 g including one polished thin section at UWB; main mass with Mr. G. Fujihara.
