Colimaite
Colimaite, the naturally occurring analog of synthetic KVS, is a sulfide mineral discovered in southwestern Mexico. The potassium- vanadium sulfide was collected from the crater of the Colima volcano. The mineral colimaite is named after the locality of this volcano and has been approved in 2007, along with its mineral name, by the Commission on New Minerals, Nomenclature and Classification (CNMNC). It has been given the International Mineralogical Association number of IMA 2007-045.
