Writeup

Writeup from MB 105:

Northwest Africa 10982 (NWA 10982)

(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 highly 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.

Geochemistry: Olivine (predominantly Fa_24.9-25.4, magnesian core Fa_3.3, Cr₂O₃ in ferroan examples <0.05 wt.%, N = 7), orthopyroxene (Fs_0.9-20.9Wo_0.8-1.5, N = 3), clinopyroxene (Fs_7.6-8.1Wo_44.6-44.4, N = 2). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.88.

Classification: Ordinary chondrite (L3).

Specimens: 75 g including one polished thin section at PSF; remainder in the Hollis Collection.
