Northwest Africa 11332 (NWA 11332)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (H4/5)

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) Some well-formed chondrules occur in a fairly coarse grained, recrystallized matrix containing relatively abundant stained metal.

Geochemistry: Olivine (Fa18.4-18.5, N = 3), orthopyroxene (Fs16.3-17.0Wo1.1-1.0, N = 2), clinopyroxene (Fs6.6-9.0Wo46.4-43.4, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 5.20.

Classification: Ordinary chondrite (H4/5).

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