Editing Analcime (section)

== Properties ==
Analcime crystals always look pseudocubic.<ref name=":0" /> Its common crystal forms include trapezohedron, truncated trapezohedron with cubic faces, and more rarely either as a truncated trapezohedron, or the crystals can take the shape of a truncated cube that is typical to bixbyites.<ref name=":2" /> The crystals can occur either individually, as interconnected, form groups on plates or even in druzy form. Crystal masses can also form veins sometimes.<ref name=":3" /> Individual crystals are [[euhedral]], meaning they have well defined faces. When on a matrix, the mineral takes a granular habit, meaning the crystals become [[Euhedral and anhedral|anhedral]].<ref name=":4">{{Cite web |title=Analcime Mineral Data |url=http://www.webmineral.com/data/Analcime.shtml |access-date=2022-12-29 |website=www.webmineral.com}}</ref> The color of the mineral varies due to trace impurities. The mineral is weakly piezoelectric and pyroelectric, meaning it produces a weak electric charge when it's rubbed or heated, hence the name analcime.<ref name=":0" /> Other characteristics include the fact that the mineral can have a blueish white fluorescence when inspected under short UV light, and a creamy white-yellow one inspected under long UV light. It does not show any pleochroic or radioactive properties.<ref name=":4" /> Analyses regarding the mineral's symmetry vary in results, however the most prevalent one being tetragonal.<ref name=":3" /> The mineral usually has polysynthetic twins, which are only visible in thin sections when the specimen is inspected under polarized analyzed light.<ref name=":2" /> Analcime mainly consists of oxygen (50.87%), silicon (25.51%), aluminum (12.26%), sodium (10.44%) but otherwise has a negligible amount of hydrogen (0.92%) as well.<ref name=":4" /> The highest quality specimens take the form of a trapezohedron, and can reach up to 25&nbsp;cm. These specimens are associated with [[serandite]], [[aegyrine]] and [[natrolite]], and can be found at [[Mont Saint-Hilaire]], [[Quebec]]. Of the pinkish-white specimens, the mineral takes the shape of well-formed cubes which can exceed 10&nbsp;cm, originating from several sites in [[Val di Fassa]], [[Trentino]], Italy.<ref name=":2">{{Cite web |title=Analcime - Encyclopedia |url=https://www.le-comptoir-geologique.com/analcime-encyclopedia.html |access-date=2022-12-29 |website=www.le-comptoir-geologique.com}}</ref>
