from The Meteoritical Bulletin, No. 106

Northwest Africa 11110

Find: 2016
Mass: 62 g (10 pieces)

Classification: Lunar meteorite (feldspathic breccia)

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

Physical characteristics: The meteorite has a black fusion crust and is partially covered by weathering products.

Petrography: (Li Y., PMO) Fine-grained mineral debris (0.01-0.6 mm), including anorthitic plagioclase, low-Ca pyroxene (Fs19.1-40.7Wo2.4-4.8) and olivine clasts (Fa30.0-38.7), are embedded by very fine-grained recrystallized matrix with anorthositic composition. Few polycrystalline igneous clasts are present. Compared to the clasts, the recystallized olivine and pyroxene are more Fe-rich (Fa40.4-42.8) and Ca-rich (Fs23.0-31.7Wo15.4-33.6), respectively. Minor unrecrystallized shock melt veins (~50 μm) are also present, which crosscut the recrystallized matrix. Accessory ilmenite, troilite and chromite are present.

Geochemistry: Plagioclase An93.6-97.6Ab2.2-6.1Or0.1-0.3; orthopyroxene Fs19.1-40.7Wo2.4-4.8, Fe/Mn=52.4-62.0; pigeonite Fs23.0-31.7Wo15.4-33.6, Fe/Mn=50.0-70.8; olivine in clast Fa30.0-38.7, Fe/Mn=86.0-109.6; olivine in matrix Fa40.4-42.8, Fe/Mn=89.7-117.0.

Classification: Lunar feldspathic melt breccia

Specimens: 12.5 g is on deposit at PMO, Ke Zuokai holds the main mass.
