Writeup from MB 111:

Awdar Labied 001        23.790°N, 13.759°W

Western Sahara

Find: 2020 Nov

Classification: HED achondrite (Eucrite, brecciated)

History: Found in November 2020 and purchased from a dealer in Ouarzazate, Morocco, by the ATTARIK Foundation in September 2021 for archiving and educational display at Hassan II University of Casablanca.

Physical characteristics: One large stone (5072 g) lacking fusion crust plus many smaller fragments.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed predominantly of crystalline debris with eucrite composition (predominantly exsolved pigeonite and calcic plagioclase) together with sparse lithic clasts with eucrite composition (with subophitic to intergranular textures and the same major mineralogy). Sparse larger grains of low-Ca pyroxene (up to 1.6 mm, lacking augite exsolution lamellae) and calcic plagioclase (up to 0.7 mm) are present. Accessory phases include silica polymorph, ilmenite, low-Ti chromite, troilite and rare pentlandite.

Geochemistry: Low-Ca pyroxene (Fs54.8-55.3Wo1.8-2.0, FeO/MnO = 32-33, N = 3), augite (Fs21.9-22.2Wo44.9-44.2, FeO/MnO = 29-35, N = 3), plagioclase (An88.6-92.2Or0.4-0.2, N = 3).

Classification: Eucrite breccia.

Specimens: 7.6 g including one polished thin section at UWB; remainder held by the ATTARIK Foundation at FSAC.
