NWA 6026 was first recovered out of the Saharan Desert of Morocco in 2009. It was analyzed and classified as a Karoonda-type of carbonaceous chondrite (CK5). It has a dark grey matrix with scattered black chondrules and blobby CAI's. This was a single stone find that weighed a modest 244 grams before cutting. This meteorite first appeared on the market in early 2010 and quickly vanished into collections. It is rarely seen now.
The specimen being offered here is a fresh interior fragment that weighs approx. 072g (72mg)

Northwest Africa 6026 (NWA 6026)
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
