Northwest Africa

Purchased: 2016

Classification: HED achondrite (Eucrite, unbrecciated)

History: Purchased from Moroccan finder September 2016.

Physical characteristics: Single stone, weathered fusion crust, a saw cut reveals an unbrecciated, medium to fine-grained mix of plagioclase and pyroxene grains. One very thin (<1 mm) shock melt veinlet was observed.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows approximately 60% pyroxene and 40% plagioclase. Many of the pyroxene grains show exsolution lamellae.

Geochemistry: (C. Agee and B. Ha, UNM) Low-Ca pyroxene Fs63.1±0.8Wo1.9±0.3, Fe/Mn=32±1, n=6; clinopyroxene Fs48.8±9.7Wo19.4±11.2, Fe/Mn=32±1, n=7; plagioclase An85.6±4.3, n=4.

Classification: Unbrecciated eucrite
