Writeup from MB 105:

Northwest Africa 10967 (NWA 10967)

(Northwest Africa)

Purchased: 2016 May

Classification: Ordinary chondrite (L3)

History: Purchased by Ben Hoefnagels in May 2016 from a dealer in Ouarzazate, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Unequilibrated with well-formed, closely packed chondrules (apparent diameter 400±300 μm) set in a finer matrix containing stained metal and minor merrillite.

Geochemistry: Olivine (Fa2.5-75.9, Cr2O3 in ferroan examples 0.03-1.17 wt.%, mean 0.33±0.40 wt.%, N = 14), orthopyroxene (Fs2.8Wo0.8; Fs16.3Wo4.0), clinopyroxene (Fs6.1Wo27.1; Fs9.4Wo38.0). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.63.

Classification: Ordinary chondrite (L3). The wide range in olivine composition coupled with the very wide range in measured Cr2O3 contents in ferroan olivine implies a very low petrologic subtype, quite similar to that determined for L3.1/3.2 chondrite Meteorite Hills 96503 by Grossman and Brearley (2005, Figs. 4 and 15a).

Specimens: 25.07 g including one polished thin section at UWB; remainder with Mr. B. Hoefnagels.
