Mass: 95.1 g
meteorite (basaltic regolith breccia)
oriented 95.1 g shield-shaped stone with partial thin, pale brown fusion
crust found in Algeria or Morocco was purchased in Tagounite
by a Moroccan dealer for A. and G. Hupé (Hupé)
in 2004 April. The specimen has a thin, dark weathering varnish, but the
interior is a very fresh, black, hard, vitreous-looking rock with small
white to yellowish clasts.
and mineralogy (S. Kuehner and A. Irving, UWS):
Polymict breccia consisting of mineral and lithic clasts derived predominantly
from mare basalt and mare microgabbro
lithologies, and additionally some highlands clasts, in a very fine
grained, mostly crystalline and partly vitreous, vesicular matrix. Mineral
clasts include calcic plagioclase (An86-97), pyroxenes (orthopyroxene,
ferropigeonite, ferrosilite, pyroxferroite;
FeO/MnO = 68.9-75.8), olivine (mostly Fa30-43, but ranging to
nearly pure fayalite; FeO/MnO = 81.9-94.2), ilmenite, Ni-poor Fe metal,
troilite, Cr-bearing ulvöspinel, and rare pentlandite, baddeleyite, and a
Ce-Ca-Fe-bearing, Zr-rich titanate (probably
zirconolite). A further description can be found in (Kuehner et al., 2005).
(R. Korotev, WUSL):
INAA of several subsamples indicate that this specimen is dominated by mare
components with ~20% lunar highland components (Korotev and Irving, 2005).
(D. Rumble, CIW):
analyses of two whole rock fragments by laser fluorination gave δ18O
= +5.83&‰, 5.96‰, δ17O = +3.06‰, 3.10‰, Δ17O
= -0.03‰, -0.05‰, respectively.
Specimens: type specimens, 19.5 g, two polished thin sections,
and one polished mount, UWS;
main mass, Hupé.
