Writeup from MB 90:

Northwest Africa 2914

Morocco

Find: April 2005

Achondrite (eucrite, monomict breccia)

History: Three paired partial stones weighing a total of 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 features that include alternating bands of cataclastic and melt flows, mylonite-like swirls and lenticular masses, and rounded, finely crushed breccia clasts that are 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 high degree of shock and low degree of weathering.

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