*A 'teaching' slice is a slice that is thick enough to be used for outreach and handled by students and enthusiasts without fear of breaking. Typically collectors prize rare meteorite slices that are ultra-thin and maximize surface area to weight ratios. This is the exact opposite, and is prized for its durability.
Top Meteorite offers exceptional quality specimens at very reasonable prices.

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.
