caption_attribution_description: English: Microlite, Muscovite Locality: Ipê mine, Governador Valadares, Doce valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org) Size: 2.2 x 1.7 x 0.6 cm. This specimen features several transparent golden-orange crystals of the rare oxide Microlite on yellowish-green Muscovite from the Ipê mine in Brazil. These crystals are some of the best quality (despite their small size) Microlite crystals you'll find. A great little specimen for one of the less common oxides out there. Ex. Brian Kosnar Collection. Deutsch: Mikrolith, Muskovit Fundort: Ipê mine, Governador Valadares, Doce valley, Minas Gerais, Southeast Region, Brasilien (Fundort bei mindat.org) Größe: 2.2 x 1.7 x 0.6 cm.
context_page_description: This list includes those recognised minerals beginning with the letter M. 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.
  The list is divided into groups:
  Introduction •
  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 'IMA2019'.
  The minerals are sorted by name, followed by the structural group or chemical class, the year of publication, 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.
  Abbreviations:
  ᴰ – discredited.
  Q – questionable/ doubtful.
