Natrolite is a mineral that occurs in cavities in basalts and other igneous rocks as one of the last minerals to forms, and also occurs as a filling in seams in granites, gneisses, and syenites.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eNatrolite is pyroelectric and piezoelectric, and will generate a charge in response to temperature and pressure changes, respectively.

Other zeolites in the natrolite group are Mesolite, Scolecite, Thomsonite and Gonnardite; all have similar modes of occurrence, molecular structures, and physical properties, even though they have different crystal symmetries: mesolite and scolecite crystallize in the monoclinic system (three unequal axes with one inclined to the plane of the other two), whereas Natrolite, Thomsonite, and Gonnardite crystallize in the orthorhombic system (three unequal axes at right angles to one another). Mesolite is chemically intermediate between Natrolite and Scolecite.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eNatrolite was one of the first zeolite minerals for which cation-exchange properties (dissolved sodium, potassium, calcium, and magnesium readily replacing one another in the molecular structure) were discovered.

Analcime consists of hydrated sodium aluminium silicate in cubic crystalline form. Its chemical formula is NaAlSi₂O₆·H₂O. Minor amounts of potassium and calcium substitute for sodium.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eAnalcime is a member of the Zeolite group and often occurs together with other zeolites. However, it is closely related in structure to the Feldspathoid group and is occasionally also classified as a Feldspathoid together with the similar mineral Leucite. However, most mineralogical sources, including the IMA, classify Analcime only as a Zeolite and not as a feldspathoid.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eAlthough the crystal structure of Analcime appears isometric its is usually off by only a fraction of an angle. This technically removes its classification from the isometric crystal system. Analyses of different Analcime crystals have yielded multiple results in crystal symmetry, with the most prevalent symmetry being tetragonal. However, truly isometric examples have been analyzed and do exist, thus making this mineral complex in its crystal classification. Due to Analcime's appearance as an isometric mineral, and the fact that isometric examples do exist, we have placed this mineral \u003c\/span\u003e\u003c\/p\u003e","brand":"NaturesgiftsByChris","offers":[{"title":"Default Title","offer_id":50267926692117,"sku":null,"price":24.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/2453\/3781\/files\/IMG_8418.jpg?v=1792125454","url":"https:\/\/naturesgiftsbychris.com\/products\/46g-australian-analcime-and-natrolite-in-basalt-specimen-a","provider":"NaturesgiftsByChris","version":"1.0","type":"link"}
