Writeup from MB 111:

Northwest Africa 14695 (NWA 14695)


Purchased: 2021

Classification: Lunar meteorite (feldspathic breccia)

History: 72 individual fragments and some smaller part fragments totaling 510 g were purchased by Steve Arnold from a meteorite dealer while visiting Zagora, Morocco, in November 2021.

Physical characteristics: Samples have a gray exterior with white clasts visible. Patches of orange caliche cover some portions of the stone. The interior shows a brecciated texture.

Petrography: Description and classification (A. Love, App). Sample is brecciated mixture of lithic and subrounded to angular mineral clasts of olivine, pyroxene and plagioclase in comminuted matrix. Lithic fragments include: anorthosite, troctolite and glassy breccias. Additional minerals are: ilmenite, chromite, barite, a silica polymorph, spinel, rare FeNi metal.

Geochemistry: (A. Love, App) Olivine (Fa26.5±7.6, Fe/Mn=76.8±4.3, n=4). Some olivine have been altered as indicated by their lower analytical totals of 90-95 wt%. Ca pyroxene (Fs23.7±4.1Wo4.0±0.3, Fe/Mn50.2±1.4, n=4); pigeonite (Fs28.1±4.0Wo19.5±12.2, Fe/Mn=39.4±12.5, n=9); high Ca pyroxene (24.0±4.1Wo33.6±4.8, Fe/Mn=47.9±3.8, n=6); plagioclase (An97.0±0.5Or0.0±0.0, n=9).

Classification: (Lunar feldspathic breccia) Textures, mineral compositions suggest this is a lunar meteorite.

Specimens: Steve Arnold holds the main masses. A polished thin section and many fragments weighing a total of 20.1 g are on deposit at App.
