Lunar Meteorite: Northwest Africa 14415
from The Meteoritical Bulletin, No. 110
Northwest Africa 14415 (NWA 14415)
Lunar meteorite (feldspathic breccia)
History: The meteorite was purchased from a dealer in Algeria.
Physical characteristics: Dark grayish fragment without fusion crust.
Petrography: (A. Greshake, MNB) Fine-grained fragmental breccia composed of mineral fragments, basaltic, and gabbroic clasts set in a fine-grained partly shock-melted feldspathic groundmass. Predominant minerals are calcic plagioclase, olivine, zoned low-Ca-pyroxene, and augite. Minor phases include ilmenite, apatite, and FeS.
Geochemistry: (A. Greshake, MNB) olivine: Fa39.5±0.3 (Fa38.7-39.9, FeO/MnO=101±11, n=15); zoned low-Ca pyroxene: Fs23.9±6.4Wo5.5±1.6 (Fs18.1-34.5Wo3.9-8.0, FeO/MnO=55±7, n=12); augite: Fs17.1±0.7Wo43.3±0.9 (Fs16.5-18.7Wo41.2-44.0, FeO/MnO=50±8, n=8); calcic plagioclase: An96.5±0.5 (An95.7-97.2, n=11).
Classification: Lunar meteorite (feldspathic breccia).
Specimens: 0.8 g at MNB. Main mass with Mateusz Szyszka
I have not studied Northwest Africa 14415. Given the small size, it is likely paired with another stone. The description is consistent with the NWA 8046 clan.
