The New IMA List of Minerals – A Work in Progress – Updated: March 2020 In the following pages of this document a comprehensive list of all valid mineral species is presented. The list is distributed (for terms and conditions see below) via the web site of the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association, which is the organization in charge for approval of new minerals, and more in general for all issues related to the status of mineral species. The list, which will be updated on a regular basis, is intended as the primary and official source on minerals. Explanation of column headings: Name : it is the presently accepted mineral name (and in the table, minerals are sorted by name). CNMMN/CNMNC approved formula : it is the chemical formula of the mineral. IMA status : A = approved (it applies to minerals approved after the establishment of the IMA in 1958); G = grandfathered (it applies to minerals discovered before the birth of IMA, and generally considered as valid species); Rd = redefined (it applies to existing minerals which were redefined during the IMA era); Rn = renamed (it applies to existing minerals which were renamed during the IMA era); Q = questionable (it applies to poorly characterized minerals, whose validity could be doubtful). IMA No. / Year : for approved minerals the IMA No. is given: it has the form XXXX-YYY, where XXXX is the year and YYY a sequential number; for grandfathered minerals the year of the original description is given. In some cases, typically for Rd and Rn minerals, the year may be followed by s.p. (special procedure): it refers to the year in which a specific action (redefinition and/or renaming) took place, and was approved by IMA. This may be related to the approval of a report by a dedicated subcommittee on a given group of minerals. Country : it is the country in which the mineral was discovered for the first time (according to the national boundaries as of today). First reference : it is the original reference for each mineral. Second reference : it is the most recent or most complete reference for each mineral, possibly including a crystal structure study. Caveat (IMPORTANT): the list includes selected information on the 5575 currently valid species; inevitably there will be mistakes in it. We will be grateful to all those who will point out errors of any kind, including typos. Please email your corrections to [email protected] .
