caption_attribution_description: English: Wavellite Locality: Mauldin Mountain Quarries, Mauldin Mt., Montgomery County, Arkansas, USA (Locality at mindat.org) Size: 8.4 x 5.9 x 5.1 cm. Deep green balls of wavellite to 1.3 follow the contours of this exposed pocket. The balls that are incomplete show their concentric structure. A few areas in Arkansas together represent the prime worldwide source for good specimens of this species. Deutsch: Wavellit Fundort: Mauldin Mountain Quarries, Mauldin Mountain, Montgomery County, Arkansas, Vereinigte Staaten (Fundort bei mindat.org) Größe: 8.4 x 5.9 x 5.1 cm.
context_page_description: This list includes those recognised minerals beginning with the letters W and X. 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.
