(Northwest Africa)

Purchased: 2014

Classification: HED achondrite (Eucrite, cumulate)

History: Purchased by Steve Arnold from Youssef Ait El Caid in Morocco, 2014.

Physical characteristics: Several identical appearing pieces with weathered exterior. A saw cut shows white plagioclase (up to ~1 mm) and brown pyroxene (up to ~3 mm) set in a dark groundmass.
