Lunar meteorite (feldspathic breccia)
Purchased by Fabien Kuntz in March 2016 from a dealer in Zagora, Morocco.

single dark stone (24.73 g) lacking fusion crust. The fresh interior contains
~30 vol% of white and beige clasts in a
fine-grained black matrix.
(A. Irving and S. Kuehner, UWS)
Relatively fine-grained breccia composed of mineral fragments (anorthite,
pigeonite, exsolved pigeonite, olivine, augite, chromite, ilmenite,
troilite, kamacite) plus some glass fragments in a finer grained matrix.
Olivine (Fa7.3; Fa26.7; Fa38.2; FeO/MnO = 74-87,
N = 3), orthopyroxene host in exsolved pigeonite (Fs34.3Wo3.2,
FeO/MnO = 48), pigeonite (Fs33.0Wo7.2, FeO/MnO = 49),
augite (Fs16.3Wo35.1-37.8; Fs11.0Wo42.3;
FeO/MnO = 36-42, N = 3), plagioclase (An96.7-97.3Or0.1,
N = 2).
Lunar (feldspathic breccia).
Specimens: 5.01 g in
the form of one polished endcut at PSF; remainder
