Writeup from MB 110:

Northwest Africa 14010 (NWA 14010)

Niger

Purchased: 2018 Dec

Classification: Carbonaceous chondrite (CV3)

History: Found in Niger in 2018 and purchased in December 2018 by Jesper Grønne from a dealer in Agadir, Morocco. A portion (142.7 g) was subsequently traded to Mark Lyon in August 2020 and an additional 12.4 g traded to Dustin Dickens.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed, unequilibrated magnetite-bearing chondrules (apparent diameter 800 ± 540 µm, N = 20) are set in about 20 vol% of a fine grained matrix containing Cr-magnetite, troilite, pentlandite and minor secondary barite.

Geochemistry: Olivine (Fa_27.5±17.0, range Fa_0.9-58.6, N = 12), low-Ca pyroxene (Fs_3.1±3.9Wo_3.0±2.0, range Fs_0.9-7.6Wo_1.1-5.0, Al₂O₃ = 1.2-2.9 wt.%, N = 3), pigeonite (Fs_1.7Wo_7.3, Al₂O₃ = 3.9 wt.%), diopside (Fs_1.0Wo_41.2), augite (Fs_29.6Wo_47.9), plagioclase (An_77.5-87.0Or_0.1-0.0, N =2), magnetite (Cr₂O₃ = 1.1 wt.%, 0.1 wt.%, N = 2).

Classification: Carbonaceous chondrite (CV3).

Specimens: 21 g including one polished mount at UWB; 650 g including 375 g main mass with Mr. J. Grønne; 121 g with Mr. M. Lyon; 12.4 g with Mr. D. Dickens.
