NWA 8455 					Location unknown

Northwest Africa

Purchased: 2014

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased from a Moroccan meteorite dealer in 2014.

Physical characteristics: Single stone, no fusion crust, irregular exterior with desert patina, freshly broken
surface and saw cut reveals a few scattered millimeter-sized white feldspar clasts set in a very dark gray groundmass.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows this specimen to be a fragmental breccia
composed of clasts (up to ~500 ?m) of individual plagioclase, pyroxene, olivine grains, and also lithic clasts
(up to ~1 mm) of gabbro and shock melt, set in a pervasive matrix of micrometer- to submicrometer-sized silicates.
Accessory ilmenite, silica polymorph, chromite, phosphate, Fe-metal.

Geochemistry: (C. Agee and N. Muttik). Olivine Fa26.63.5, Fe/Mn=1009, n=28; pigeonite Fs26.26.2Wo8.74.4,
Fe/Mn=585, n=22; augite Fs21.58.4Wo34.56.8, Fe/Mn=5511, n=11; plagioclase An95.11.0Ab4.51.0Or0.40.1, n=4.
Shock melt (proxy for bulk composition) SiO2=44.61.1, TiO2=0.590.53, Al2O3=26.13.2, Cr2O3=0.100.03, MgO=6.81.8,
FeO=5.01.3, MnO=0.040.03, NiO=0.020.01, Na2O=0.690.20, K2O=0.190.04 (all wt%).

Later one more fragments were found that are absolutely identical to the previous one.
