Purchased: 2017 Jan

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Ben Hoefnagels in January 2017 from a dealer in Zagora, Morocco.

Physical characteristics: A single stone (73.6 g) with a brownish weathered exterior and a fresh, mostly very dark gray interior with some whitish clasts.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular mineral fragments and sparse, fragmented glass spheres in a finer grained matrix containing some vesicles. Minerals are anorthite, olivine, pigeonite, ferropigeonite, fayalite, kamacite, Al-Cr-Fe-Mg spinel, zircon and minor barite. The specimen is crosscut by some glass-rich shock veins.

Geochemistry: Olivine (Fa15.5-50.5, FeO/MnO = 75-91, N = 4), pigeonite (Fs25.5-35.2Wo10.6-18.8, FeO/MnO = 58-69, N = 4), ferropigeonite (Fs63.2Wo24.4, FeO/MnO = 72), anorthite (An93.9-96.6Or0.3, N = 2).

Classification: Lunar (feldspathic regolith breccia).
