Northwest Africa 15018 (NWA 15018)

(North West Africa)

Purchased: Apr 2022

Classification: Lunar meteorite (feldspathic breccia)

Physical characteristics: Many small grayish fragments without fusion crust.

Petrography: The meteorite displays a dark grayish interior and is a polymict breccia predominantly composed of up to 3 mm sized feldspathic and melt clasts plus mineral fragments consolidated by abundant finely recrystallized feldspathic matrix. Dominant minerals are olivine, augite, pigeonite, and calcic plagioclase. Minor phases are silica, ilmenite and FeS.

Geochemistry: olivine: Fa27.7±1.7 (Fa26.3-30.6, FeO/MnO=87±4, n=12); augite: Fs17.4±1.2Wo34.9±1.4 (Fs15.3-19.1Wo33.2-37.5, FeO/MnO=47±4, n=9); pigeonite: Fs25.3±1.6Wo9.3±2.2 (Fs23.0-28.4Wo5.9-13.3, FeO/MnO=53±5, n=11); calcium plagioclase: An97.9±0.1 (An97.6-98.1, n=10)

Nice slice of L3 chondrite! When receiving, it looks less impressive then on photo's, but most of those are taken with polarized filter I suppose. Real thing still impressive, even with my glasses on!
