Northwest Africa 2914

Morocco

Find: April 2005

Achondrite (eucrite, monomictbreccia)

History: Three paired partial stones weighing a totalof 122 g were purchased in Erfoud, Morocco, in April 2005.

Petrography: (T. Bunch and J. Wittke, NAU)Cataclastic cumulate basalt that shows a remarkable range of shock featuresthat include alternating bands of cataclastic and melt flows, mylonite-likeswirls and lenticular masses, and rounded, finely crushed breccia clasts thatare separated by dark, glassy to cryptocrystalline bands.

Geochemistry: Host: orthopyroxene (Fs59.3–62.7Wo3.1–1.9;FeO/MnO = 31), exsolved augite (Fs26.8–27.8Wo43–42.1;FeO/ MnO = 28), plagioclase (An92); chromite (Cr/(Cr+Al) = 0.88).Classification: Achondrite (eucrite monomict breccia) with moderate to highdegree of shock and low degree of weathering.

Specimens: A 21.1 g type specimen is on deposit at NAU*.Birdsell holds the main mass.
