Northwest Africa 11111

Find: 2016
Mass: 111 g

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Ke Zuokai in Dec. 2016 from a Moroccan dealer.

Physical characteristics: No fusion crust; covered by weathering products.

Petrography: (Li Y., PMO) Fine-grained mineral (plagioclase, low-Ca pyroxene and olivine) clasts and anorthositic rock debris (0.01-0.6 mm) are set in the very fine-grained recrystallized matrix. Compared to those in clasts (Fa27.6-45.6), the recystallized olivines are more Mg-rich (Fa21.4-32.0). Minor unrecrystallized shock melt veins (~50 μm) are also present, which crosscut the recrystallized matrix. Accessory Fe-Ni metal, troilite, and chromite were observed.

Geochemistry: Plagioclase An96.4-99.4Ab0.5-3.5Or0.4; olivine in clast Fa27.6-45.6, Fe/Mn=77.7-111.3; olivine in matrix Fa21.4-32.0, Fe/Mn=70.9-113.5; orthopyroxene Fs22.5-51.7Wo2.0-4.8, Fe/Mn=49.9-80.8; augite Fs12.4-24.0Wo38.2-45.1, Fe/Mn=39.5-51.9; pigeonite Fs22.1-37.0Wo5.6-9.2, Fe/Mn=44.3-65.0.

Classification: Lunar feldspathic melt breccia

Specimens: 20 g is on deposit at PMO, Ke Zuokai holds the main mass.

This looks like a new one.
