Four fusion-crusted stones having a combined weight of 916 g were purchased from a Moroccan dealer at the 2004 Denver Show. A sample was submitted to Northern Arizona University (T. Bunch and J. Wittke), and NWA 2388 was classified as a CK6 carbonaceous chondrite with sparse relict chondrules within a recrystallized, equilibrated groundmass. The meteorite has experienced moderate weathering and a low shock stage, and contains abundant plagioclase. Northwest Africa 2388 is the only CK6 chondrite that was not found in Antarctica.
After in-depth analyses of many CV and CK meteorites having a wide range of petrologic types was conducted and published by Wasson et al. (2013), the necessity for merging the CK and CV groups into a single unified group has become an obvious conclusion. The geochemical and petrological justification for reclassification of the CK chondrites, along with the details of the new proposed taxonomic scheme, can be found on the Dhofar 015 page. The photo above shows a 1.4 g partial slice of NWA 2388.
