Writeup from MB 111:

Northwest Africa 14705 (NWA 14705)

Morocco

Purchased: 2019 Nov

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Ziyao Wang from a Moroccan dealer at the China International Mineral and Gem show in Beijing in November 2019.

Physical characteristics: The single stone is dark brown in color. There are some black patches of fusion crust on the surface, and some rust and white specks are visible. The interior is a fine-grained black matrix.

Petrography: Petrology (H. Chen, L. Xie, Z. Xia, GUT): It shows typical breccia structure and large-area melt. Fragmental breccia mainly composed of mineral fragments, and impact melt clasts set in a fine-grained partly shock-melted groundmass. The main minerals are calcic plagioclase, olivine and pyroxene. Minor phases include ilmenite and FeS. The matrix is dominated by very-fine particles and glass (<10 ?m). The chemical composition of the glass is similar to that of anorthite.

Geochemistry (L. Xie and H. Chen, GUT): Plagioclase: An95.7-97.2Or0-0.26 (n=12); Olivine: Fo63.7-68.3, Fe/Mn=75-95 (n=14); Pigeonite: Fs25.2-26.4Wo7.5-8.8, Fe/Mn=54-65 (n=10); High-Ca pyroxene: Fs16.6-25.2Wo26.7-42.2, Fe/Mn=39-54 (n=8)

Classification: Lunar (feldspathic breccia)

Specimens: A total of 20 g of sample and one polished mount are on deposit at GUT. The owner Ziyao Wang holds the main mass.
