Earth:List of minerals approved by IMA (I)

This list includes those recognised minerals beginning with the letter I. The International Mineralogical Association 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 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).

The list is divided into groups:

• Introduction • (Main synonyms)
• A • B • C • D • E • F • G • H • I • J • K • L • M • N • O • P–Q • R • S • T • U–V • W–X • Y–Z

The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'.

The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).

• Abbreviations:
  • ^D – discredited (IMA/CNMNC status).
  • ^Q – 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.
  • ^I – intermediate member of a solid-solution series.
  • ^H – hypothetical mineral (synthetic, anthropogenic, suspended approval procedure, etc.)
    • ^ch – incomplete description, hypothetical solid solution end member.
  • Rd – redefinition of ...
  • "s.p." – special procedure.
  • group – a name used to designate a group of species, sometimes only a mineral group name.
  • no – no link available.
  • IUPAC – chemical name.
  • Y: 1NNN – year of publication.
  • Y: old – known before publications were available.
