Meteoritical Bulletin, No. 94, September 2008. Meteoritics & Planetary Science
Find: 2007 October
Mass: 93.3 g
(lunar, feldspathic breccia)
Purchased by Greg Hupé from a Moroccan dealer in Tagounite,
Morocco in October 2007.
characteristics: A single, light colored 93.3 g stone.
The interior is light gray, mostly very fine grained with a few white
clasts (Fig. 2), and prominent but sparsely distributed metal grains (surrounded
by hydroxide staining).
(A. Irving and S. Kuehner, UWS):
Breccia composed of small gabbroic to troctolitic clasts (granular
aggregates of rounded olivine grains and calcic plagioclase enclosed within
low-Ca pyroxene with accessory Ti-chromite and troilite), sparse large
grains of kamacite (up to 1 mm, partly altered to iron hydroxide) and rare
large grains of silica polymorph in a dominant, very fine grained matrix of
the same phases. There are secondary (terrestrial) veinlets and small
patches of calcite.
Low-Ca pyroxene (Fs22.3-22.8Wo5.9-5.3, FeO/MnO =
51.9-53.0; Fs20.8-36.1Wo7.4-12.0, FeO/MnO =
56.5-58.3), olivine (Fa27.2-36.9, FeO/MnO = 87.7-96.3),
plagioclase (An94.9-96.4Or0.3-0.1). Bulk composition
(R. Korotev, WUSL):
FeO 8.5 wt.%, Sc 19.2 ppm, Sm 1.1 ppm, Th 0.6 ppm, Ni 450 ppm.
Achondrite (lunar, feldspathic breccia).
Specimens: A total of 18.7 g and one polished thin section are on
deposit at UWS.
The main mass is held by Mr. G. Hupé.
