Editing Stilbite (section)

== Localities ==
Stilbite is abundant in the volcanic rocks of [[Iceland]], [[Faroe Islands]], [[Isle of Skye]], [[Bay of Fundy]], [[Nova Scotia]] (where it is the provincial mineral), northern [[New Jersey]] and [[North Carolina]]. Salmon-pink crystals occur with pale green [[apophyllite]] in the [[Deccan Traps]] near [[Mumbai]] (Bombay) and [[Pune District|Pune]], [[India]]; white sheaf-like groups encrust the calcite ([[calcite|Iceland-spar]]) of Berufjord near Djupivogr in Iceland; brown sheafs are found near [[Paterson, New Jersey]] in the [[United States]]; and crystals of a brick-red color are found at Old Kilpatrick, [[Scotland]].{{sfn|Spencer|1911}}

Iceland is generally considered to be the [[type locality (geology)|type locality]] for stilbite-Ca.  It is presumed to be the Helgusta Iceland Spar Mine, along Reydarfjordur.  Excellent white bow ties of stilbite are found here on calcite and quartz, associated with heulandite and [[laumontite]] in cavities.<ref name=ZW/>

The type locality for stilbite-Na is Cape Pula, [[Pula, Sardinia|Pula]], [[Cagliari]] Province, [[Sardinia]], [[Italy]].  Small, lustrous, white or pink, pointed blades of stilbite-Na, and formless masses, up to 5&nbsp;cm in diameter, have been found there, covering a thin crust of reddish [[heulandite]] in large fractures and cavities in the highly weathered volcanic [[andesite]] or [[rhyolite]].

The [[Tertiary]] Deccan basalts of western India are the most prolific sources of stilbite in the world.  Stilbite is the most abundant zeolite in the [[tholeiitic basalt]] plateaux near [[Nasik]] and Pune and decreases in abundance toward the coast at Mumbai.<ref name=ZW/>
