The Meteoritical Bulletin, No. 106
Mass: 62 g (10 pieces)
Lunar meteorite (feldspathic breccia)
Purchased by Ke Zuokai in
Dec. 2016 from a Moroccan dealer.
characteristics: The meteorite has a black fusion crust
and is partially covered by weathering products.
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.
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.
