Writeup from MB 105:

Northwest Africa 10980 (NWA 10980)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (LL3)

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 highly magnesian cores in olivine and orthopyroxene. Well-formed, fairly closely packed chondrules (apparent diameter 500-400 μm) are set in a finer matrix containing stained metal and minor chlorapatite.

Geochemistry: Olivine (Fa0.7-29.9, Cr2O3 in ferroan examples 0.02-0.13 wt.%, mean 0.06±0.04 wt.%, N = 7), orthopyroxene (Fs1.9-22.7Wo0.5-1.8, N = 3), pigeonite (Fs19.1Wo12.6), subcalcic augite (Fs15.2Wo33.0, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.41.

Classification: Ordinary chondrite (LL3).

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