Northwest Africa 11472 (NWA 11472)
Lunar meteorite (feldspathic breccia)
History: A single stone was found in March 2017 by a nomad in an undisclosed region of the Sahara. The stone was later purchased by Luc Labenne.
Physical characteristics: A single grayish stone. Cut surface reveals a gray interior with mm sized light gray and white clasts.
Petrography: (J. Gattacceca, H. Pourkhorsandi, CEREGE): Brecciated igneous rock. Clasts of anorthite (to 5 mm), olivine, pyroxene set in a feldspathic matrix. Opaque minerals: ilmenite, chromite, troilite, metal (to 40 μm).
Geochemistry: Olivine Fa39.7±13.2, range Fa19.6-55.1, FeO/MnO=101.0±19.1 (N=8). Pyroxene Fs33.1±9.3Wo, FeO/MnO=65.9±10.7 (N=8). Plagioclase An96.1±1.0Ab3.8±0.9Or0.1±0.1 (N=6). Chromite Cr/(Cr+Al)=0.56, TiO2=11.4wt%, Al2O3=15.4wt%, Cr2O3=28.4wt% (N=2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 2.82.
Classification: Lunar, feldspathic breccia
Specimens: 2 g at CEREGE. Main mass with Luc Labenne.
I have not studied NWA 11472. It may be another NWA 8046 pair.
