The

La première
météorite lunaire d'Afrique avec un
nom et coordonnées!
Anoual
32°44'4.5"N, 2°57'28.7"W
Anoual, Morocco.
Find: May 3 2006
Achondrite (Lunar, mare basalt/gabbro
breccia)
History: Nomads from near Anoual (a village located in the East of Morocco between
Bouarfa and Talsint; about 40 km E-N-E of the latter) learned that the small
odd stones that had been found close to their settlement in June and July of
2005 was indeed a meteorite from the Moon (NWA 2727). After extensive searching
and screening of the soil, Mr. Boujena recovered 12 pieces for a total mass of
5.92 g, over a small area of about 5 m in diameter. The small size of the pieces
can be explained by the brecciated character of the stone. Ph. Thomas visited
the place in May 2006 and May 2007, participated in the search, took pictures,
in particular of the investigated soil and registered the GPS coordinates.
Physical characteristics: Tan greenish stones devoid of fusion crust.
Petrography: (A. Jambon, O. Boudouma and D. Badia. UPVI). Breccia composed dominantly
of two lithologies: A phyric basalt and a gabbro. Basalt with subhedral olivine
phenocrysts (<1mm; 20 vol%) slightly resorbed in a finely crystallized groundmass.
Highly fractured gabbro clasts. Small doleritic clasts with zoned pyroxenes.
Mafic areas of once molten rock with olivine needles. One clast of quenched basaltic
melt with numerous zirconolite needles (0.7 vol%; 0.1 mm) silica and celsian
K-spar. Ilmenite, troilite, chromite. Plagioclase and clinopyroxene. Carbonate
fills the largest fractures.
Geochemistry: (EMPA) Olivine (Fa45-28, with few crystals >Fa45; FeO/MnO =
97). Pyroxene: from (Mg#= 0.80) pigeonite (Wo10) and augite (Wo45) to pyroxferroite
(Fs70Wo25; FeO/MnO = 70). Plagioclase (An91-83). Spinel (Cr66Sp25Us3Mt6).
Classification: Lunar mare basalt/gabbro breccia. Paired with NWA
2727/3160 (and
potentially NWA
3333)
Type specimens: A total of 1.205 g of sample (one polished section) is on deposit
at UPVI. Mr. Ph. Thomas holds the main mass.
During
our recent trip in Morocco, we recovered 7
additional pieces of Anoual, for
a total of 2.757 g.
We have already given 20 % (0.552g) of this new
batch as complementary mass to the reference
specimen.
New
fragments
available,
only 5 fragments
between 0.033g to 1.656g.
