Northwest Africa 11006

Purchased: November 2016
Mass: 2245 g

Classification: lunar, anorthositic impact melt breccia

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

Physical characteristics: A single stone lacking fusion crust. The section of stone looks gray and the stone has a dark yellow surface. Small white clasts are visible in a pale, finer grained matrix.

Petrography: (Wu Y., PMO) Lithic clasts and mineral fragments (0.15 to 2 mm) set in a poorly recrystallized anorthositic matrix. The lithic clasts are impact melt clasts and rocks of anorthositic, gabbroic, noritic, and troctolitic composition. Mineral fragments are dominated by pyroxene grains and minor olivine. Some pyroxene grains exhibit exsolved lamella composed of augite Fs23.5Wo40.4 and pigeonite Fs43.6Wo10.3. Vesicles occur in the matrix or some clasts with skeletal crystals. Other accessory minerals include chromite, spinel, ilmenite and troilite. The meteorite is moderately weathered with clay minerals filled in irregular cracks.

Geochemistry: Plagioclase (An95.9±1.7Or0.3±0.3, n=21), olivine (FeO/MnO = 83.2-116.5), pyroxene FeO/MnO = 43.9-73.6.

Classification: Lunar, anorthositic impact melt breccia.

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