Own a real piece of the Moon with this amazing Moon Meteorite!
Lunar (moon) Meteorites are among the most popular and sought-after moon meteorites, the total weight of lunar meteorites ever found is incredibly low compared to usual meteorites. NWA 7986 is classified as a feldspathic granulitic breccia, similar samples of which had been recovered at most Apollo lunar highland sites.
Moon Meteorite Designation: NWA 7986
Physical characteristics: A single, broken, irregular conical stone (606g) partially covered by translucent, pale greenish fusion crust and with a pale grey-brown interior.
Petrography: (A. Irving and S. Kuehner, UWS) Abundant partly devitrified, glassy matrix (with "swirly" texture) containing embedded small mineral and lithic clasts. Minerals are olivine, orthopyroxene, pigeonite, augite, anorthite, ilmenite, troilite and minor kamacite.
Geochemistry: Olivine (Fa33.4-34.5, FeO/MnO = 83-96), orthopyroxene (Fs34.7Wo2.3, FeO/MnO = 53), pigeonite (Fs25.8Wo6.3, FeO/MnO = 53), augite (Fs14.5Wo41.7; Fs33.5Wo39.5, FeO/MnO = 38-68), anorthite (An96.2-98.5Or0.1). Bulk composition (R. Korotev, WUSL): INAA of subsamples gave mean abundances of FeO 5.6 wt.%, and (in ppm) Sc 31, La 13.2, Sm 6.2, Eu 1.39, Yb 4.0, Th 1.9.
Classification: Lunar (feldspathic vitric breccia). On the basis of mineralogy, texture and bulk composition, this specimen is paired with NWA 4936, NWA 5406, NWA 6221, NWA 6355, NWA 6470, NWA 6570 and NWA 7190.
How do we know it is a real piece of the Moon?
The moon is constantly hit by meteorites itself and with no atmosphere and little gravity the larger impacts will eject lunar rocks into space. After this impact, this meteorite will eventually be brought down to Earth by the Earth's gravitational pull. Scientists and universities all around the world examine meteorites and compare them with known lunar material, e.g. samples collected during the Apollo missions. The composition of gases and isotopes found is so unique that they can say for sure the material originated from the moon.
