caption_attribution_description: English: Stilbite-Ca, Natrolite, Laumontite, Heulandite-Ca Locality: Long Point Beach, Kings County, Nova Scotia, Canada (Locality at mindat.org) Size: 8.7 x 8.7 x 5.8 cm. A rich combination specimen of 4 zeolite species from a classic, now hard-to-access zeolite locale in Canada. The radiating natrolite crystals are protected in a pocket with associated stilbite. The matrix around and above the pocket is lined with small, stable, pink-colored laumontite crystals (this is an unusual color). Heulandite, rare for the locale, is also present as a crystal cluster on the backside. Ex. Harold Urish Collection.

context_page_description: Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material. Based on this, he called the material zeolite, from the Greek ζέω, meaning "to boil" and λίθος, meaning "stone". The classic reference for the field has been Breck's book Zeolite Molecular Sieves: Structure, Chemistry, And Use.
  Zeolites occur naturally but are also produced industrially on a large scale. As of December 2018, 245 unique zeolite frameworks have been identified, and over 40 naturally occurring zeolite frameworks are known. Every new zeolite structure that is obtained is examined by the International Zeolite Association Structure Commission and receives a three letter designation.
