A body formed in July 2006 and charged with developing coherent guidelines for mineral nomenclature. The CNMNC resulted from the merger of the International Mineralogical Association (IMA), the Commission on New Minerals and Mineral Names (CNMMN), and the Commission on Classification of Minerals. The CNMMN was established in 1959 with the purpose of regulating the introduction of new minerals and mineral names, and of rationalizing mineralogical nomenclature. The CNMNC consists of representatives appointed by national mineralogical bodies, and an executive committee comprising a chair, two vice-chairs, and a secretary.
