Writeup from MB 104:

Northwest Africa 10044 (NWA 10044)

(Northwest Africa)

Purchased: January 2015

Classification: HED achondrite (Eucrite, polymict)

History: Purchased in New York City from a Moroccan dealer.

Physical characteristics: One piece. A saw cut shows many dark, fragmental clasts up to 2 mm set in light-gray groundmass.

Petrography: (C. Agee, UNM) This eucrite consists of two lithologies, one is an equilibrated basaltic eucrite and the other is an unequilbrated basaltic eucrite. This is a fragmental breccia with some grains up to ~2 mm set in a fine-grained cataclastic groundmass. There are a few shock melt clasts present. Accessory phases include ilmenite, troilite, phosphate, and silica.

Geochemistry: (C. Agee and N. Muttik, UNM) Equilibrated low-Ca pyroxene Fs55.2±1.0Wo5.5±1.5, Fe/Mn=32±2, n=10; equilibrated augite Fs32.0±3.2Wo36.0±4.6, Fe/Mn=31±1, n=4; zoned pigeonite Fs45.4±4.2Wo9.0±2.4, Fe/Mn=32±1, n=10; plagioclase An91.9±1.3Ab7.7±1.3Or0.4±0.1, n=8.

Classification: Polymict eucrite
