Writeup from MB 110:

Northwest Africa 6026 (NWA 6026)

(Northwest Africa)

Purchased: 2009

Classification: Carbonaceous chondrite (CK5)

History: The meteorite was purchased from a local meteorite dealer in Erfoud, Morocco.

Physical characteristics: Dark grayish rock partly covered with fusion crust.

Petrography: The meteorite displays a grayish to dark greenish interior and is composed of sparse, still clearly defined chondrules (apparent mean diameter about 800 µm) set in abundant recrystallized Fe-rich matrix. The dominant mineral phase is ferroan Ni-bearing olivine. Minor phases are Ca-pyroxene and plagioclase. Opaques phases are sulfides, and abundant Cr-rich magnetite; no metal was found.

Geochemistry: olivine: Fa31.0±0.2 (Fa30.5-31.3, NiO=0.47±0.04 wt%, n=11); Ca-pyroxene: Fs10.5±0.9Wo47.1±0.8 (Fs9.1-12.1Wo46.0-48.8 n=7); feldspar: An34.9-84.1Ab16.0-61.7Or0.2-3.4, n=8; magnetite contains 5.4±0.1 wt% Cr2O3, n=3
