    en.wikipedia.org/wiki/Ferritungstite 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.. This list contains mineral synonyms, varieties and polytypes.
