Writeup from MB 105:

Northwest Africa 10886 (NWA 10886)

(Northwest Africa)

Purchased: 2016

Classification: HED achondrite (Eucrite, monomict)

History: Purchased by Gary Fujihara in Morocco, June 2016.

Physical characteristics: Single stone, weathered exterior without fusion crust. A cut and polished surface reveals a breccia with clasts up to 1.5 cm set in a dark-gray shock-melted groundmass.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows a fragmental breccia with basaltic clasts bounded by zones of shock melt.

Geochemistry: (C. Agee and M. Spilde, UNM) Low-Ca pyroxene Fs60.1±3.6Wo3.6±1.4, Fe/Mn=31±1, n=7; augite Fs27.4±0.7Wo42.5±0.3, Fe/Mn=33±2, n=3; plagioclase An89.2±0.6, n=4.

Classification: Eucrite (monomict), equilibrated basaltic clasts of a single lithology with compositional separation of low Ca-pyroxene and augite.

Specimens: 31.72 g including a probe mount on deposit at UNM, Gary Fujihara holds the main mass.
