Northwest Africa 16179 (NWA 16179)
Northwest Africa
Purchased: 2023
Classification: Acondrite HED (Eucrite)
History: Numerous samples weighing a total of 3.2 kg were found in northwest Africa. Salek Mrabih acquired the sample from a meteorite dealer in June 2023.
Physical characteristics: The stones have a rounded shape and lack a fusion crust. The cut face is light gray in color and exhibits a brecciated texture.
Petrography: Description and classification (A. Love, App.). The sample exhibits a brecciated texture, dominated by anhedral fragments of exsolved pyroxene and plagioclase. The average grain size of the plagioclase feldspar is 65.6 µm (n=20). Other minerals include a silica polymorph, apatite, ilmenite with Cr, chromite, and troilite.
Geochemistry: (A. Love, App) low Ca-piroxene content (Fs 65.3±1.1 Wo 2.8±1.2, Fe/Mn=31.1±0.5 n=12); high Ca-piroxene content (Fs 31.0±1.5 Wo 41.0±1.5, Fe/Mn=31.3±1.2 n=12); plagioclase (An 92.1±1.1 or 0.2±0.1, n=12).
Classification: Acondrite HED (low-weathering eucritic breccia M-S2) Based on textures and mineral compositions, the sample is a balanced basaltic eucritic breccia with M-S2 and low weathering.
Specimens: Salek Mrabih (Dominion meteorites) contain the main masses. A thin polished section and seven small individuals weighing 20.2 g are deposited.
