NWA 11303 is a lunar meteorite recovered near Tindouf, Algeria in 2017! Lunar meteorites are rocks ejected into space by asteroid impacts on the moon. Some of this debris was captured by the gravitational pull of the Earth.
NWA 11303 was found by Mauritanian dealer and scientifically analyzed by A. Irving and S. Kuehner at University of Washington's Department of Earth and Space Sciences department.
This lunar material had fragmented into smaller pieces during entry of Earth's atmosphere, and these are some of those fragments.
This piece measures 1.8g and can be shipped worldwide!
SCIENTIFIC DATA VIA METEORITIC SOCIETY:
Physical characteristics: Many small fragments coated by pale reddish-brown terrestrial weathering products. The fresh interiors of the largest fragments exhibit white to beige clasts in a dark gray, fine-grained matrix. [Total known mass: 6Kg]
Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular mineral grains of anorthite, olivine, orthopyroxene, exsolved pigeonite, ferroan pigeonite, augite, ilmenite, Ti-chromite and fayalite in a partly vesicular matrix containing minor kamacite and barite.
Geochemistry: Olivine (Fa26.7-47.2, FeO/MnO = 75-81, N = 2), orthopyroxene (Fs24.1Wo3.6, FeO/MnO = 67), orthopyroxene host (Fs47.1Wo3.3, FeO/MnO = 68), ferroan pigeonite (Fs52.4Wo18.8, FeO/MnO = 67), augite (Fs8.0Wo44.3, FeO/MnO = 35), plagioclase (An96.7-97.4Or0.2-0.1, N = 2).
Classification: Lunar (feldspathic regolith breccia).
