Writeup from MB 106:

Northwest Africa 11246 (NWA 11246)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (L3)

History: Purchased by an anonymous collector from a dealer at the Munich Show in 2005, subsequently acquired by the Hollis Collection and donated to the Planetary Studies Foundation.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely packed, well-formed chondrules (apparent diameter 400±300 μm) are set in a finer grained matrix containing altered metal.

Geochemistry: Olivine (Fa4.5-43.1, Cr2O3 in ferroan examples <0.02 wt.%, N = 7), orthopyroxene (Fs2.1-20.0Wo0.3-0.7, N = 3), clinopyroxene (Fs2.9-8.9Wo43.9-41.8, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.91.

Classification: Ordinary chondrite (L3).

Specimens: The entire specimen including one polished thin section is at PSF.
