Writeup from MB 110:

Northwest Africa 14344 (NWA 14344)

(Northwest Africa)

Purchased: 2021

Classification: Primitive achondrite (Winonaite)

History: Purchased by Mendy Ouzillou from Saïd Yousfi.

Physical characteristics: Eight identically appearing pieces, exterior has a brown and black colored sandblasted patina with irregular surfaces. Freshly broken surface reveals a light brown and gray fine-grained groundmass of silicates, with metal and sulfide scattered throughout.

Petrography: (C. Agee and A. Ross, UNM) Microprobe examination and reflected light microscopy of a polished mount shows a texturally equilibrated mosaic of olivine, enstatite and diopside with grain size in the range 100-300 μm, many triple junctions are present. Kamacite, taenite, and troilite make up approximately 10% of this meteorite, most grains are 100-300 μm in diameter. Cl-rich apatite was detected. Scarce albitic plagioclase was found.

Geochemistry: (A. Ross, UNM) Olivine Fa4.0±0.1, Fe/Mn=18±1, n=6; enstatite Fs4.8±0.2Wo1.8±0.2, Fe/Mn=12±1, n=4; diopside Fs1.5±0.4Wo45.6±0.5, Fe/Mn=10±1, n=3; plagioclase Ab75.4±0.1An21.4±0.3, n=2.

Classification: Primitive achondrite (Winonaite) likely paired with NWA 13917.

Specimens: 20.9 g including a probe mount on deposit at UNM, Mendy Ouzillou holds holds the main mass.
