Writeup from MB 106:

Northwest Africa 11326 (NWA 11326)

(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 PSF.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely packed chondrules (apparent diameter 500±400 μm, N = 12) occur within a reddish-brown matrix.

Geochemistry: Olivine (Fa2.2-46.8, Cr2O3 in ferroan examples 0.04-0.13 wt.%, mean 0.07±0.03 wt.%. N = 8), orthopyroxene (Fs1.7-40.3Wo0.1-3.1, N = 3), pigeonite (Fs17.4Wo21.8), augite (Fs9.7Wo35.4). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.72.

Classification: Ordinary chondrite (L3).

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