The Meteoritical Bulletin, No. 106
Mass: 111 g
Lunar meteorite (feldspathic breccia)
Purchased by Ke Zuokai
in Dec. 2016 from a Moroccan dealer.
characteristics: No fusion crust; covered by weathering
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.
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,
