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
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.
