Northwest Africa 14068 (NWA 14068)

(Northwest Africa)

Purchased: 2020 Oct

Classification: Enstatite chondrite (EL7)

History: Purchased by Ziyao Wang in October 2020 from a dealer in Laayoune, Morocco.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Thoroughly recrystallized, enstatite-rich assemblage with accessory kamacite, sodic plagioclase, daubreelite and Cr-troilite. No remnant chondrules were observed in the studied thin section. Kamacite has been extensively altered to Fe hydroxides, which also stain grain boundaries throughout the specimen.

Geochemistry: Enstatite (Fs0.5±0.2Wo1.6±0.0, range Fs0.3-0.7Wo1.6, N = 2), plagioclase (Ab75.4An20.0Or4.6), kamacite (Ni = 6.1 wt.%, Si = 1.0 wt.%).

Classification: Enstatite chondrite (EL7).

Specimens: 27.0 g including one polished thin section at UWB; remainder with WangZ.
