Northwest Africa 14809 (NWA 14809)
Algeria
Purchased: 2021
Classification: Carbonaceous chondrite (CK5)
History: Found in Algeria. Bought by Jean Redelsperger from Mohamed Elguirah in 2021.
Physical characteristics: Dark fragments.
Petrography: (J. Gattacceca, CEREGE) Chondrule with average apparent diameter about 800 µm set in a recrystallized matrix (grain size 15 µm). Olivine is the dominant mineral. Magnetite and sulfide are abundant in the matrix and chondrules, sometimes as composite spherical grains up to 200 µm.
Geochemistry: Olivine Fa33.3±0.4, NiO 0.48±0.27 wt% (n=5). Ca-pyroxene Fs7.0Wo49.6 (n=1). Plagioclase An22.9Ab73.1Or4.0 (n=2). Magnetite Cr2O3 3.26 wt% (n=2).
Classification: Carbonaceous chondrite (CK5).
Specimens: Type specimen at CEREGE. Main mass with Jean Redelsperger.
