Meteorite (feldspathic breccia)
Purportedly found with other similar stones near Al Mahbas,
southern Morocco, and purchased by Fabien Kuntz in May 2015 from a dealer
in Agadir, Morocco.
characteristics: A single small stone (21.73
g) lacking fusion crust. The interior exhibits white, pale orange and light
gray clasts set in a gray matrix (~25 vol.%).
(A. Irving and S. Kuehner, UWS)
Fragmental breccia composed of mineral clasts of anorthite, olivine,
pigeonite, augite, subcalcic augite, ferropigeonite, fayalite, silica
polymorph, Ti-Al-chromite, ilmenite, troilite and rare baddeleyite in a
finer grained matrix.
Olivine (Fa37.0-39.9, FeO/MnO = 97, N = 2), pigeonite (Fs29.1Wo,
FeO/MnO = 55), ferropigeonite (Fs65.9Wo7.3, FeO/MnO =
70), subcalcic augite (Fs20.5Wo25.4; Fs64.7Wo25.2;
FeO/MnO = 55-70), augite (Fs31.6Wo37.5, FeO/MnO =
74), fayalite (Fa73.9, FeO/MnO = 106), plagioclase (An91.1-91.4Or0.1-0.4,
N = 2). Bulk composition (R.
Korotev, WUSL): INAA of
subsamples gave the following mean abundances (in wt.%) FeO 15.3, Na2O 0.30; (in ppm) Sc 30.2, Ni
140, La 5.0, Sm 2.47, Eu 0.67, Yb 1.9, Lu 0.28, Hf 1.8, Th 0.8.
Lunar (feldspathic breccia).
4.44 g including a polished endcut at PSF; remainder with Kuntz.
