Writeup

Writeup from MB 106:

Northwest Africa 11234 (NWA 11234)

(Northwest Africa)

Purchased: 2016 Nov

Classification: Ordinary chondrite (LL3)

History: Purchased by Fabien Kuntz in November 2016 from a dealer in Nouakchott, Mauritania.

Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, well-formed chondrules (apparent diameter 700±400 µm) are set in a sparse, fine-grained matrix containing chlorapatite. An autolithic clast is present in the studied thin section.

Geochemistry: Olivine (Fa_0.5-50.9, Cr₂O₃ in ferroan examples = 0.02-0.44 wt.%, N = 7), orthopyroxene (Fs_0.8-23.9Wo_0.9-1.4, N = 3), clinopyroxene (Fs_7.3-7.9Wo_35.1-45.7, N = 2). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.32.

Classification: Ordinary chondrite (LL3).

Specimens: 22.02 g including one polished thin section at PSF; remainder with Kuntz.
