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.

After in-depth analyses of many CV and CK meteorites having a wide range of petrologic types was conducted by Wasson et al. (2013), they presented a reasonable case for merging the CK and CV groups into a single unified group. The geochemical and petrological justification for reclassification of the CK chondrites, along with the details of this proposed taxonomic scheme, can be found on the Dhofar 015 page. Importantly, a subsequent study was conducted by Dunn et al. (2016) which compared magnetite in a number of CK and CV chondrites. They presented geochemical, mineralogical, and petrographic evidence which is more consistent with separate CV and CK parent bodies; details of their study can also be found on the Dhofar 015 page. The photo above shows a 1.4 g partial slice of NWA 2388.
