Mauritania

Purchased: 2017

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased in Mauritania by Dustin Dickens from anonymous meteorite hunter.

Physical characteristics: Many visually identical appearing pieces, ranging from several kilograms to sub-gram fragments. Some pieces show a light-gray, remnant fusion crust on one or more faces, with most having no fusion crust. Saw cut reveals a fragmental breccia with white feldspathic clasts set in a dark-gray ground mass.

Petrography: (C. Agee, UNM) This meteorite is a polymict breccia of fragmental feldspathic, troctolitic and mafic lithologies, as well as fragmental pyroxene, olivine, plagioclase grains, and shock melt with vescicles.

Agee, UNM) olivine Fa: 25.6±8.9, Fe/Mn=95±18, n=13; low-Ca pyroxene Fs26.2±8.8Wo6.2±2.5, Fe/Mn=52±4, n=7; subcalcic augite Fs35.9±5.8Wo26.9±7.9, Fe/Mn=69±5, n=2; augite Fs14.5±7.1Wo41.0±2.0, Fe/Mn=45±15, n=3; plagioclase An96.2±0.8, n=6; Shock melt (20 _m defocused electron beam, proxy for bulk meteorite composition): SiO2=42.9±0.4, TiO2=0.11±0.05, Al2O3=31.1±4.0, Cr2O3=0.10±0.05, MgO=5.1±3.3, FeO=3.3±2.0, MnO=0.05±0.05, CaO=16.6±1.6, Na2O=0.37±0.06, K2O=0.04±0.00 (all wt%), n=3.
