Writeup from MB 109:

Northwest Africa 13036 (NWA 13036)

Morocco

Purchased: 2019 Oct

Classification: Lunar (feldsp. melt breccia)

History: A group of stones found together near Tichiya, southern Morocco, was purchased jointly by Adam Aaronson and Ahmad Bouragaa.

Physical characteristics: The stones (total weight 1780 g) lack fusion crust but have a dark external weathering patina. Interiors are light gray and very fine grained with visible tiny rounded vesicles.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Very fine grained specimen dominated by microvesicular, melt-textured crystalline material surrounding sparse small feldspathic lithic clasts. Minerals are anorthite, olivine, orthopyroxene, subcalcic augite, chromite, troilite and secondary barite.

Geochemistry: Olivine (Fa28.6-36.8, FeO/MnO = 73-93, N = 7), orthopyroxene (Fs17.4Wo3.4, FeO/MnO = 58), subcalcic augite (Fs23.0Wo20.3, FeO/MnO = 42), anorthite (An95.9-97.5Or0.1, N = 3).

Classification: Lunar (feldspathic melt breccia).

Specimens: 21 g including one polished mount at UWB; remainder with A. Bouragaa and Aaronson.
