Northwest Africa 11380 (NWA 11380)

(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 PSF.

Petrography: (A. Irving and S. Kuehner, UWS) Some well-formed chondrules occur in a recrystallized matrix containing relatively abundant altered metal.

Geochemistry: Olivine (Fa19.0-19.1, N = 3), orthopyroxene (Fs16.3-16.4Wo1.4-1.3, N = 2), clinopyroxene (Fs5.5-6.25Wo46.0-45.2, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.92.

Classification: Ordinary chondrite (H4/5).

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