Writeup from MB 111:

Northwest Africa 14594 (NWA 14594)

(Northwest Africa)

Purchased: 2021

Classification: Lunar meteorite (melt breccia)

Petrography: (K. Metzler, IfP) Achondritic breccia, consisting of lithic clasts (up to 10 mm) and mineral fragments (plagioclase, Ca-poor and Ca-rich pyroxenes, and olivine) set in a partly vesicular crystallized melt. Lithic clast are mainly subrounded fragments of clast-rich melt brecias. Accessories are ilmenite and troilite.

Geochemistry: Mineral compositions and geochemistry: Ca-poor pyroxene: Fs30.2±3.0Wo7.5±1.3 (Fs23.7-33.6Wo4.7-8.8); mean Fe/Mn (at.): 59.1; n=8. Ca-rich pyroxene: Fs18.0±1.8Wo32.6±1.2 (Fs16.7-19.3Wo31.8-33.5); mean Fe/Mn (at.): 51.5; n=2. Olivine: Fa37.5±0.3 (Fa37.1-37.9); mean Fe/Mn (at.): 103.8; n=9. Plagioclase An96.7±0.8Or0.1±0.1 (An95.9-98.8Or0.0-0.4); n=13.

Classification: Lunar (melt breccia), based on texture and mineral chemistry
