Writeup from MB 109:

Northwest Africa 13191 (NWA 13191)

Southern Provinces, Morocco

Find: 2015

Classification: Lunar meteorite (feldspathic breccia)

History: The meteorite was purchased by Guilin Geological Museum from Bing-an Miao, the owner of Huizhou Caiyuan Meteorite Technology Co., Ltd, Guandong, China.

Physical characteristics: It is a single specimen without fusion crust and has a typical breccia structure that consists of dark gray matrix and white clasts with size of a few mm, up to 5 mm. There are some fractures inside the sample.

Petrography: Petrology (H. Chen, Z. Xia, B. Miao, GUT): The meteorite is a feldspathic breccia composed of lithic clasts, mineral clasts, and vitric clast, set in a fine-grained, vesicular and partly vitreous matrix. The lithic clasts consist of anorthosite, gabbro, peridotitic anorthosite, gabbro anorthosite, and troctolite. Mineral clasts are mainly anorthite, orthopyroxene, clinopyroxene, pyroxene with exsolution lamella, olivine, and ilmenite.

Geochemistry (Z.Xia, GUT): Plagioclase (maskelynite): An91.2-99.9Or0-2.73(n=29); Olivine: Fo51.8-68.9, Fe/Mn=85.7-97.6 (n=8); Pyroxene: Fs14.6-66.0En10.8-78.8Wo3.0-43.0, Fe/Mn=42.2-78.7 (n=26); silica: SiO2: 97.3-97.9, TiO2:0.30-0.38, Al2O3:1.13-1.41, CaO: 0.43-0.52; Na2O:0.32-0.39 (n=3).

Classification: Lunar (felspathic breccia)

Specimens: A polished thin section and about 20 g sample are stored in the Institution of Meteorites and Planetary Materials Research of GUT, the main mass is exhibited in the Guilin Geological Museum.
