caption_attribution_description: English: Quartz, Rock crystal, SiO2; Staatliches Museum für Naturkunde Karlsruhe, Germany. Used in homeopathy as remedy: Silicea (Sil.) Deutsch: Quarz, Bergkristall, SiO2; Staatliches Museum für Naturkunde Karlsruhe, Deutschland. In der Homöopathie als Arzneimittel verwendet: Silicea (Sil.)
context_page_description: This list includes those recognised minerals beginning with the letters P and Q. 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.
