	STILBITE (Hydrated Sodium Calcium Aluminum Silicate)
		Stilbite is a common and perhaps the most popular zeolite mineral for collectors.
		Stilbite's hallmark crystal habit is unique to stilbite and a rarer but related zeolite called stellerite.
		Stilbite's structure has a typical zeolite openness about it that allows large ions and molecules to reside and actually move around inside the overall framework.

	Stilbite - LoveToKnow 1911
		STILBITE, a mineral of the zeolite group consisting of hydrated calcium aluminium silicate, CaAl2(S103)6+6H20.
		The colour is usually white, sometimes red, and on the perfect cleavage (parallel to the plane of symmetry) the lustre is markedly pearly; hence the name stilbite given by R. Haiiy in 1796, from Gr.
		Stilbite is a mineral of secondary origin, and occurs with other zeolites in the amygdaloidal cavities of basic volcanic rocks; it is sometimes found in granite and gneiss, and exceptionally in metalliferous veins.

	Stilbite, rock, crystal, mineral, gem stone, birth stones - mineralgallery
		A common habit of stilbite is as crystals in cruciform penetration twins.
		The sheaf-like aggregates, cleavage and lustre of stilbite are characteristic.
		Stilbite occurs mainly in amygdaloidal cavities in basalts and similar eruptive rocks, usually associated with other zeoolitesand with calcite.

	Stilbite
		Stilbite was found in clusters of indistinct crystals in cavities of a porous replacement area in pegmatite.
		The feldspar has been replaced by epidote, actinolite, and calcite, and stilbite was one of the last minerals to crystallize in the cavities.
		Stilbite was also found in crystals, with tennantite, galena, sphalerite, and actinolite, in the Sterling Hill mine at the 900-foot level.

	Stilbite Information about the mineral specimen, gem or Crystal
		Stilbite is a commonly found zeolite, that forms nice crystals inside the bubbles and fisures of volcanic rocks that have undergone a small amount of metamorphism.
		Stilbite is sometimes found to have rounded knobs with radiating structures and twins may also be found.
		Stilbite has a typical zeolite openness that allows large ions and molecules to reside and actually move around inside the overall framework.

	STILBITE Chapter 19. Tectosilicates and silicates with unknown structures
		Stilbite is the most abundant of the zeolites at Franklin and Sterling Hill, yet it is a rare mineral.
		Stilbite is a sodium calcium aluminum silicate hydrate mineral of the zeolite group.
		Stilbite was reported by Palache (1935) to occur at Franklin in altered pegmatite with epidote, actinolite, and calcite.

		Stilbite is a tectosilicate mineral of the zeolite group consisting of hydrated calcium aluminium silicate, NaCa
		The color is usually white, sometimes red, and on the perfect cleavage (parallel to the plane of symmetry) the lustre is markedly pearly; hence the name stilbite, from Greek, "to shine".
		Stilbite is a mineral of secondary origin, and occurs with other zeolites in the amygdaloidal cavities of basaltic volcanic rocks; it is sometimes found in granite and gneiss, and exceptionally in hydrothermal veins.

	OhioLINK ETD: Feng, Xiahong
		Oxygen isotope studies have been carried out for zeolites stilbite, analcime, heulandite and clinoptilolite in order to evaluate the suitability of using δ18O values of natural zeolites as indicators of conditions of their formation.
		Isotope exchange experiments between water vapor and framework oxygen of stilbite, analcime, heulandite and clinoptilolite show that these minerals are isotopically exchangeable at low temperatures to a far greater extent than chemically similar minerals with more closed structures, such as feldspars.
		Using the Arrhenius equation, the activation energies of self-diffusion are calculated to be 15.9 kcal/mole for stilbite and 20.1 kcal/mole for analcime.

	Stilbite
		Stilbite was declared the provincial mineral in November 1999.
		Stilbite is a variety of zeolite, mined mainly on the west coast of North America.
		Another capability of stilbite is the ability to attract calcium and magnesium so that it can be used in water softening.

	Stilbite (Site not responding. Last check: )
		Stilbite is a sodium calcium aluminum tetra-silicate, in essence a zeolite.
		Stilbite tends to be white when pure, orange when iron is present and pink varieties are known as well.
		Usually, stilbite is twinned so that a group of the crystals form "wheat sheaves" or "bowties" and are very showy when contrasted to their basalt matrix.
