Writeup from MB 104:

Northwest Africa 10205 (NWA 10205)

(Northwest Aftica)

Purchased: 2015

Classification: Primitive achondrite (Lodranite)

History: Purchased by Adam Aaronson in Morocco, 2015.

Physical characteristics: Weathered exterior; saw cut reveals dark brown crystals ~2 mm in diameter.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous pyroxene grains some of which are up to 2000 μm, finer-grained (50-200 μm) olivines are also present. Numerous metal and iron oxide veinlets throughout. Kamacite and troilite detected, plagioclase is absent.

Geochemistry: (C. Agee and N. Muttik, UNM) Olivine Fa10.8±0.2, Fe/Mn=24±0, n=6; low-Ca pyroxene Fs9.8±0.3Wo1.6±0.4, Fe/Mn=14±0, n=3; diopside Fs3.9±0.3Wo43.8±0.5, Fe/Mn=9±1, Cr2O3=1.16±0.09 (wt%), n=3.

Classification: Lodranite, not an acapulcoite, based on grain size and absence of plagioclase.

Specimens: 5 g including a probe mount on deposit at UNM; Aaronson holds the main mass.
