Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Bob Falls in May 2017 from a dealer in Zagora, Morocco.

Physical characteristics: This fresh stone (150.87 g) lacks fusion crust and consists of angular white to beige clasts in a dark-gray matrix.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia consisting of mineral clasts of anorthite, olivine, orthopyroxene, pigeonite, exsolved pigeonite, augite, ilmenite, chromite, plus some polymineralic lithic clasts, within a fine grained, partly vesicular matrix of the same minerals with minor kamacite, taenite, troilite, pentlandite, calcite and barite.

Geochemistry: Olivine (Fa5.6-54.0, FeO/MnO = 77-109, N = 3), orthopyroxene (Fs24.4-46.0Wo4.6-3.4, FeO/MnO = 56-67, N = 3), pigeonite (Fs49.5Wo19.7, FeO/MnO = 58), augite (Fs22.2Wo40.7, FeO/MnO = 64), plagioclase (An92.7-97.8Or0.5-0.2, N = 2).

Classification: Lunar (feldspathic breccia).
