Writeup from MB 113:

Northwest Africa 16470 (NWA 16470)

Morocco

Purchased: May, 2021

Classification: Lunar meteorite (feldspathic breccia)

History: In May 2021, Xin Li purchased the meteorite, originally discovered in Morocco, from Peng Wang, a dealer in Xinjiang, China.

Physical characteristics: The specimen is irregular in shape, retains a small amount of fusion crust, is grayish-black in color, and is coated with a substantial amount of yellow terrestrial materials.

Petrography: The polished section of the specimen reveals that mineral and lithic clasts are distributed in a dark fine-grained feldspathic matrix. Fractures in the mineral clasts and melt veins are observed in this section. The lithic clasts consist largely of anorthosite, with a minor amount of troctolitic granulites. Mineral clasts predominantly consist of plagioclase, with a small amount of pyroxene and olivine. Fusion crust is also observed in the polished section. Trace phases include ilmenite, troilite, and Fe-Ni metal.

Geochemistry: Geochemisry: Plagioclase: An95.99-97.19Or0.00-0.49(n=12); Olivine: Fo54.5-80.2, Fe/Mn=81-111 (n=9); pyroxene: Fs23.9-35.3Wo4.0-28.2En44.3-71.2, Fe/Mn=51-75(n=5)

Classification: lunar (feldspathic breccia)

Specimens: The main mass is in the possession of Xin Li from Chengdu University of Technology, while a cut piece of 2.1 g and one polished thin section are on deposited at GUT.
