Northwest Africa 14343 (NWA 14343)

(Northwest Africa)

Purchased: 2020

Classification: Ordinary chondrite (LL6, melt breccia)

History: Purchased from a Moroccan meteorite dealer in August 2020.

Petrography: (C. Agee, A. Ross, UNM) Reflected light microscopy shows numerous texturally equilibrated clasts of type 6 ordinary chondrite material. Plagioclase grains are up to 150 microns in size. Ubiquitous minor troilite was detected with the electron microprobe.

Geochemistry: (A. Ross, UNM) Olivine Fa31.6±0.2, Fe/Mn=63±2, n=7; low-Ca pyroxene Fs25.5±0.4Wo1.6±0.3, Fe/Mn=39±2, n=7.
