Northwest Africa 11479



Purchased: 2017 September

Mass: 504 g


Lunar meteorite (feldspathic breccia)


History: Purchased by Ke Zuokai in Sept. 2017 from a Moroccan dealer.


Physical characteristics: The meteorite has no fusion crust with an irregular shape. Small white clasts are visible.


Petrography: (W. Hsu, PMO) Lithic clasts and mineral fragments (10 to 500 μm) are set in a fine-grained anorthositic matrix. Mineral fragments are dominated by anorthite and pyroxene grains with minor olivine. Some pyroxene grains exhibit exsolved lamella structures. Maskelynite is present. Other accessory minerals include taenite, chromite, ilmenite and troilite.


Geochemistry: Plagioclase An94.1-97.9Or0.0-0.7, (average: An96.9±1.1Or0.2±0.2, n=13); Olivine Fa17.8-44.9, Fe/Mn (cation ratio) = 77.7 - 124.7, (average = 99.2±15.3, n=13 ); pigeonite Fs29.8-59.4En35.0-52.5Wo5.6-21.5, Fe/Mn (cation ratio) =57.4-74.4 (average=64.7±5.7, n=8); augite Fs7.4-27.6En29.1-49.1Wo38.4-43.5, Fe/Mn (cation ratio) =37.3-75.1 (average=58.4±12.1, n=10); minor orthopyroxene Fs36.3En61.0Wo2.7, Fe/Mn (cation ratio)=54.7, n=1.


Classification: Lunar feldspathic breccia based on texture and composition.


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