Writeup from MB 105:

Northwest Africa 10972 (NWA 10972)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (L3)

History: Purchased by an anonymous collector from a dealer at the Munich Show in 2005 and subsequently acquired by the Hollis Collection.

Petrography: (A. Irving and S. Kuehner, UWS) Unequilibrated with more magnesian cores in olivine and orthopyroxene. Well-formed, fairly closely packed chondrules (apparent diameter 450±300 µm) are set in a finer matrix containing stained metal and minor merrillite.

Geochemistry: Olivine (predominantly Fa24.6-29.6, magnesian core Fa8.8, Cr2O3 < 0.04 wt.%, N = 7), orthopyroxene (Fs7.4-19.2Wo0.2-1.0, N = 3), clinopyroxene (Fs8.4-10.7Wo43.6-42.6, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.62.

Classification: Ordinary chondrite (L3).

Specimens: 121 g including one polished thin section at PSF; remainder in the Hollis Collection.
