Northwest Africa 11303 (NWA 11303)

(Northwest Africa)

Purchased: 2017 Mar

Classification: Lunar meteorite (feldspathic breccia)

History: Material excavated from a site near Tindouf, Algeria, was purchased by Dustin Dickens in March 2017 from a Mauritanian dealer. The coordinates of the site are unknown.

Physical characteristics: Many small fragments coated by pale reddish-brown terrestrial weathering products. The fresh interiors of the largest fragments exhibit white to beige clasts in a dark gray, fine-grained matrix.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular mineral grains of anorthite, olivine, orthopyroxene, exsolved pigeonite, ferroan pigeonite, augite, ilmenite, Ti-chromite and fayalite in a partly vesicular matrix containing minor kamacite and barite.

Geochemistry: Olivine (Fa26.7-47.2, FeO/MnO = 75-81, N = 2), orthopyroxene (Fs24.1Wo3.6, FeO/MnO = 67), orthopyroxene host (Fs47.1Wo3.3, FeO/MnO = 68), ferroan pigeonite (Fs52.4Wo18.8, FeO/MnO = 67), augite (Fs8.0Wo44.3, FeO/MnO = 35), plagioclase (An96.7-97.4Or0.2-0.1, N = 2).

Classification: Lunar (feldspathic regolith breccia).

Specimens: 20.0 g including one polished endcut at UWB; remainder with Mr. D. Dickens.
