Northwest Africa 11301 (NWA 11301)

(Northwest Africa)

Purchased: 1995

Classification: Ordinary chondrite (LL3)

History: Purchased by Ken Regelman in 1995 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely packed, well-formed chondrules (apparent diameter 700400 μm, N = 15) occur in a sparse matrix.

Geochemistry: Olivine (Fa1.4-53.0, Cr2O3 in ferroan examples 0.02-0.07 wt.%, mean 0.030.02 wt.%, N = 8), orthopyroxene (Fs4.6-25.3Wo0.4-3.4, N = 3), clinopyroxene (Fs1.3-2.8Wo46.7-46.5, N = 2). Magnetic susceptibility log χ ( 10-9 m3/kg) = 4.32.

Classification: Ordinary chondrite (LL3).

Specimens: 21.8 g including one polished thin section at UWB; remainder with mr. K. Regelman.
