Purchased: 2014 Feb
Mass: 704.5 g
meteorite (feldspathic breccia)
Purportedly found in Mauritania and purchased by Darryl Pitt in February
2014 from a dealer in Nouadhibou, Mauritania.
characteristics: Single stone (704.5 g) composed of
light gray to beige clasts in a dark gray matrix.
(A. Irving and S. Kuehner, UWS)
Fragmental breccia consisting of angular clasts in a finer grained matrix.
Minerals are olivine orthopyroxene, subcalcic augite, augite, diopside),
anorthite, ilmenite, troilite, rare kamacite and taenite. Several small
mare basalt clasts were observed.
Olivine (Fa21.7-47.0, FeO/MnO = 80-85, N = 3), orthopyroxene (Fs32.3-47.7Wo2.9-2.7,
FeO/MnO = 53-65), subcalcic augite (Fs45.3-51.6Wo25.6-21.4,
FeO/MnO = 55-59), augite (Fs13.7-14.2Wo44.3-44.0,
FeO/MnO = 36-39), diopside (Fs8.7Wo40.8, FeO/MnO =
38), plagioclase (An96.9-97.4Or0.1-0.2). Bulk composition (R. Korotev, WUSL)
INAA of subsamples gave the following mean abundances (in wt.%) FeO 4.3, Na2O
0.39; (in ppm) Sc 8.5, Ni 66, La 2.7, Sm 1.18, Eu 0.81, Yb 1.10, Lu 0.156,
Hf 0.94, Th 0.7.
Lunar (feldspathic fragmental breccia).
Specimens: 20.1 g
including one polished thin section at UWB. The main mass is held by DPitt.
