What is a new mineral? Bahariyaite (KMnO4) as a case

Each year some new minerals are added to the known list of minerals. For a new mineral to be approved, it should full fill certain criteria and go through a long procedure. A proposal by the criteria, including geological, physical, optical, chemical and crystallographic features of the new phase has to be presented to the Commission on New Minerals, Classification and Nomenclature (CNMNC) of the International Mineralogical Association. A proposal of a new mineral Bahariyaite, with the composition (KMnO4) has been recently approved by the CNMNC. The steps of approval and criteria of the mineral will be presented. In addition the significance and importance of this discovery will be discussed.
