Crystals of serandite, natrolite, analcime, and aegirine from Mont Saint-Hilaire, Quebec, Canada

Mineralogy is an active science in which minerals are discovered or recognised on a regular basis. Use of old mineral names is also discontinued, for example when a name is no longer considered valid. Therefore, a list of recognised mineral species is never complete.

Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.

The International Mineralogical Association (IMA) is the international scientific group that recognises new minerals and new mineral names. However, minerals discovered before 1959 did not go through the official naming procedure. Some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). Presently, each year about 90–110 new mineral species (the sum of all mutations c. 120 per year) are officially approved by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association.<ref name=CNMNC2007>Template:Cite journal</ref>

Template:As of, the IMA - CNMNC List of Minerals lists 6,145 valid minerals, including 1,153 pre-IMA minerals (grandfathered), and 97 questionable minerals.<ref name="IMAMineralsCount">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Also Template:As of, the Mineralogical Society of America's Handbook of Mineralogy lists 5,663 species,<ref name="HandbookMiner">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and the IMA Database of Mineral Properties/RRUFF Project lists 6,006 valid species (IMA/CNMNC) of a total of 6,237 minerals.<ref name="rruff">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The IMA/RRUFF database includes 1,164 pre-IMA minerals.<ref name="rruff"/>

Due to the length of this list, it is divided into alphabetical groups. The minerals are sorted by name.

  • Abbreviations:
    • "*" – discredited (IMA/CNMNC status).
    • "s.p." – special procedure.
    • Q or "?" – questionable/doubtful (IMA/CNMNC, mindat.org or mineralienatlas.de status).
    • N – published without approval of the IMA/CNMNC, or just not an IMA approved mineral but with some acceptance in the scientific community nowadays. The 'IMA database of mineral properties' (rruff.info/ima) has 173 species with 'not an IMA approved mineral' tag, some are an intermediate member of a solid solution series, others are "recently" discredited minerals.<ref name="rruff" />
    • I – intermediate member of a solid-solution series.
    • H – hypothetical mineral (synthetic, anthropogenic, etc.)
    • group – a name used to designate a group of species, sometimes only a mineral group name.

Working practices

  • The name of a new mineral is kept confidential by the IMA until it is approved or until its full description is published, its authors' option (approved decision: 'IMA2009-D').<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref> The IMA uses a code for its own procedures for the supposed new mineral (and so it is a synonym). Ferri-ottoliniite's proposal was assigned code 'IMA2001-067', it was redefined and approved as 'IMA2001-067a' in 2003, for instance (the ottoliniite root name is discredited since 2012).<ref name="hawthorne2012" />

  • Current IMA regulations do not allow substances of anthropogenic origin (burning coal mine dumps, coal mine fires, slag, etc.) to be validated as a mineral species. Since 1998, the majority of polymorphs (especially polytypes and polytypoids) are not regarded as separate mineral species anymore.<ref>Template:Cite journal</ref>
  • IMA/CNMNC identifiers are usually written without space, as years don't get meaningful hits on Google search.
  • "The System of Mineralogy of James Dwight Dana and Edward Salisbury Dana" (8 ed.) was the reference of CNMNC/CNMMN's (IMA) initial work. At the Kobe 2006 general meeting, the IMA council endorsed the creation of an Internet site on minerals ('rruff.info/ima'). So a Master List was needed and the older minerals were reviewed in a document of 130 pages. The final GQN List was published (grandfathered, questionable and published without approval) after a final review of Burke E A J and Nickel E H (approved decision: 'IMA2006-C'). Not only the well established minerals before 1959 was grandfathered (G), but the minerals that could not be discredited as well. The merging of the 'ARD List' (approved, revalidated and discredited) with the 'GQN List' resulted in the first 'IMA/CNMNC List of Mineral Names'. The 2007 draft of the 'IMA/CNMNC List of Mineral Names' was a courtesy of the Materials Data, Inc. (MDI), its 2009 review had important modifications.<ref>Template:Cite book</ref><ref>Template:Cite book</ref> The RRUFF database was built with the help of the MDI's 2007 draft, the IMA Master List is an update of the MDI's 2009 review.<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> Some grandfathered minerals had their status changed to approved afterwards, based on IMA approved reports. The list of approved minerals was revised with 'The New IMA List of Minerals (September 2012)'.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

    • The review and approval of new mineral is straight forward most of the time, but there are exceptions. Proposal IMA2009-096 was not accepted, proposal IMA2009-096a was approved as fontarnauite (6.DA.60) in 2014. Proposal IMA1995-020 was not accepted, proposal IMA1995-020c was approved as jarandolite (6.CB.25).<ref name="may2015"/>
    • Some valid names get discredited (in the broader senseTemplate:Clarify).
  • Some old minerals were known before their 20th century names were first published.
