Lunar (regolith breccia)
History: Found in the region of Almabas near the frontier between Morocco and Algeria.
Physical characteristics: One stone with no visible fusion
crust. Recognized as a lunar breccia by L. Labenne.
Petrography: (R. Hewins, S. Pont, B. Zanda, MNHNP)
This is a breccia composed mainly of crystal clasts a few hundred μm
in size, with a few glassy to dendrite-bearing spherules about 1 mm in
size. Matrix is very fine-grained, in some cases glass with schlieren, with
vugs or vesicles. There are a few breccia clasts up to 4 mm, very fine
grained (1-2 μm) and in some cases with igneous textures (i.e.
clast-laden melt rock clasts). Breccia clasts contain feldspathic igneous
clasts with intersertal textures resembling Apollo 14310 but finer, as well
as crystal clasts and rare lithic chips. Some pyroxene clasts show
exsolution. Accessory minerals include troilite, ilmenite, a silica phase
and, in the largest melt-rock, Ni-bearing metal.
Geochemistry: Mineral compositions and
Geochemistry: (R. Hewins ans S. Pont, MNHNP) The pyroxene compositions are
Fs36.7Wo7.6 to Fs55.3Wo19.6,
and the atomic Fe/Mn falls just below the UNM lunar line with average ratio 71. Both magnesian and
ferroan olivine clasts are present, with FeO/MnO of 103 falling just below
the lunar value. Spinel contains ~40 wt% Cr2O3.
Plagioclase is An93.6Ab6.2Or0.2. The
glassy matrix is basaltic (sensu lato).
Classification: (R. Hewins MNHN) Lunar breccia. The meteorite contains anorthite with
olivine and pyroxene Fe/Mn ratios matching lunar. As it contains Ni-rich metal,
glass spherules and breccia clasts it is classified as a regolith breccia.
Specimens: The main mass (31 g) is held by Labenne. The type specimen consists
of 0.977 g and 6.88 g at MNHNP.

(Northwest Africa)
Purchased: 2015
Mass: 14.4 g
Classification: Lunar meteorite
History: This stone was one of a group found
in northwest Africa, near to the Morocco/Algeria border; exact date and
weights of other stones is unknown. Purchased in 2015 from a Moroccan
Dealer in Morocco.
Physical characteristics: The total mass of the single stone was 14.4 g, and is dark
brown in color with a dark brown/black fusion crust.
Petrography: H. Ashcroft, M. Anand, OU. A
fragmental breccia containing a variety of mineral (up to 1 mm) and lithic
(up to 1 × 3 mm) fragments in a dark matrix composed of finer-grained
crystals and a dark, vesicular glass. Both basaltic and feldspathic
fragments are present in roughly equal proportions. The breccia has a
seriate fabric and the proportion of glass and crystals in the matrix
varies throughout the sample. Some crystals exhibit evidence for shock and
alteration (offset pyroxene lamellae, recrystallized and maskelynitised plagioclase). Minor secondary calcite
veins and barite are seen throughout the sample. Minerals are Olivine
(forsteritic and fayalitic), Pyroxene (Orthopyroxene, Pigeonite, Augite),
Anorthite and trace amounts of ilmenite, chromite, kamacite, schreibersite,
apatite, merrilite, silica.
Geochemistry: Feldspar crystals are anorthitic and vary between An80-90,
with an average of An94 (N = 184). Some feldspars are
recrystallized, and others have been maskelynitised.
A continuum of pyroxene compositions (pigeonite to augite) are observed
with a range in Fs15-64, and Wo5-43. Four main
clusters in olivine composition are observed with Fa37, Fa51
and Fa70. Some Fayalite (Fa90) is also observed. One
mafic clast contains orthopyroxene (Wo3En75Fs22),
Olivine, (Fa75) and anorthite (An95). One
hedenbergite-fayalite-silica symplectite is observed. The oxygen isotopes
(R. Greenwood and I. Franchi, OU)
are consistent with a lunar origin with δ17O 3.42 ‰, δ18O
6.51 ‰, Δ17O 0.03 ‰. Average FeO/MnO for Olivine is 105,
and Pyroxene is 66.
