caption_attribution_description: English: Gmelinite-Na, Chabazite-Ca Locality: Wasson Bluff, Parrsboro, Bay of Fundy, Cumberland County, Nova Scotia, Canada (Locality at mindat.org) Size: 4.1 x 2.8 x 1.9 cm. This is a dramatic cluster of large gmelinites to about an inch, which have replaced chabazite. The lustre is unusually good on this piece, almost glassy and so far better than on others I have seen in the past! This is new material collected recently from this classic old locality that is difficult to access, by my friend Rod Tyson (a semi-retired mineral dealer and well-known Canadian field collector!). Deutsch: Gmelinit-Na, Chabasit-Ca Fundort: Wasson Bluff, Parrsboro, Bay of Fundy, Cumberland County, Nova Scotia, Kanada (Fundort bei mindat.org) Größe: 4.1 x 2.8 x 1.9 cm.
context_page_description: This list includes those recognised minerals beginning with the letter G. 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.
