The International Mineralogical Association (IMA) is the international group that recognises new minerals and new mineral names. However, minerals discovered before 1959 did not go through the official naming procedure although some minerals published previously have been either confirmed or discredited since that date. Abbreviations: "*" – discredited (IMA/CNMNC status). "?" – questionable/doubtful (IMA/CNMNC, mindat.org or mineralienatlas.de status). N – published without approval of the IMA/CNMNC. I – intermediate member of a solid-solution series. H – hypothetical mineral (synthetic, anthropogenic, etc.) ch – incomplete description, hypothetical solid solution end member. group – a name used to designate a group of species, sometimes only a mineral group name. no – no link available. red. – redefinition of ... Y: 1NNN – year of publication. Y: old – known before publications were available. List of main synonyms Mainly renamed minerals and synonyms used by the Handbook of Mineralogy.
