Laâyoune 002 

Saguia el Hamra, Western Sahara
Find: 2022 January
Mass: 5148 g (2 pieces)

Lunar meteorite (feldspathic breccia)

History: Found near Laayoune, Morocco, in January 2022 and purchased from the finder by Aziz Habibi.

Physical characteristics: Both stones (3680 g, 1468 g) lack fusion crust and have a similar overall gray color with some whitish clasts visible.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed of mineral clasts of anorthite, olivine, orthopyroxene, pigeonite and augite plus accessory ilmenite, chromite (with variable Ti content) and minor secondary barite.

Geochemistry: Olivine (Fa46.3-46.7, FeO/MnO = 94-98, N = 4), orthopyroxene (Fs33.5Wo3.8, FeO/MnO = 57), pigeonite (Fs36.9-45.1Wo6.5-8.4, FeO/MnO = 57-64, N = 3), augite (Fs19.1-20.9Wo39.1-39.7, FeO/MnO = 53-54, N = 2), anorthite (An96.1-97.7Or0.3-0.1, N = 3).

Classification: Lunar (feldspathic breccia).

Specimens: 20.7 g in the form of a polished endcut at UWB; remainder with Mr. A. Habibi.

Laâyoune 003 

Saguia el Hamra, Western Sahara
Find: 2022 July 16
Mass: 340.38 g (many pieces)

Lunar meteorite (feldspathic breccia)

History: Bought by Emilie Cèbe and Arnaud Valz-Blin (Eclectic-Art) on July 16, 2022, from Jérémy Bassemon, who had bought the material from an Algerian dealer.

Physical characteristics: Many cm-sized light gray fragments.

Petrography: (J. Gattacceca, CEREGE) Mineral clasts of mostly anorthite and pyroxene set in a glassy feldspathic matrix. Clasts are up to 1 mm, most of them a few 100 µm. Accessory minerals: chromite, ilmenite, and secondary barite. Rare metal, including grains Ni rich grains (up to 25 wt% Ni).

Geochemistry: Pigeonite Fs29.8±1.3Wo6.0±1.2, FeO/MnO = 64.5±6.9 (n=4). Anorthite An95.7Ab4.0Or0.3 (n=4).

Classification: Lunar (feldspathic breccia).

Specimens: Type specimen at CEREGE. Main mass with Robert Joulin, and some material with Emilie Cèbe and Arnaud Valz-Blin (Eclectic-Art).

Randy Says…

I have not studied Laâyoune 002 and 003. Despite that the petrographic descriptions are not self-evidently similar I assume that the meteorites are paired because the reported find locations are 0.2 km apart.
