Writeup from MB 106:

Northwest Africa 11352 (NWA 11352)

Morocco

Purchased: Feb. 2017

Classification: Lunar feldspathic breccia

History: Purchased by Ke Zuokai in Feb. 2017 from a Moroccan dealer.

Physical characteristics: The meteorite has a black fusion crust. Small white clasts are visible.

Petrography: Lithic clasts and mineral fragments (0.1 to 1.1 mm) set in a fine-grained anorthositic matrix. The lithic clasts has a gabbroic, anorthositic, or minor noritic composition. Mineral fragments are dominated by anorthite and pyroxene grains with minor olivine. Some pigeonite grains exhibit exsolved lamella of augite. Vesicles occur in the matrix and some clasts. Other accessory minerals include chromite, ilmenite and troilite.

Geochemistry: Plagioclase An95.7-97.9Or0.01-0.3 (average: An96.8±0.6Or0.1±0.1, n=16); Olivine Fa0.9-31, Fe/Mn (cation ratio)=92.9-116.3 (average=98.2±8.6); pigeonite Fs19.9-46.6Wo6.2-18.0; minor orthopyroxene Fs33.1-47.9Wo1.9-3.1 and augite Fs11.4-52.4Wo28.8-41.8, pyroxene Fe/Mn (cation ratio)=47.0-68.4 (average=58.4±6.0).

Classification: Lunar feldspathic breccia classification based on texture and composition.
