(ˈskɒlɪˌsaɪt; ˈskəʊl-)
(Minerals) a white zeolite mineral consisting of hydrated calcium aluminium silicate in groups of radiating monoclinic crystals. Formula: CaAl2Si3O10.3H2O
[C19: scolec- from Greek skōlēx scolex + -ite1]


(ˈskɒl əˌsaɪt, ˈskoʊ lə-)

a white zeolite mineral, a hydrous calcium aluminum silicate, CaAl2Si3O10∙3H2O, occurring in masses and in needle-shaped crystals.
[1815–25; < Greek skōlēk-, s. of skṓlēx worm, grub + -ite1 (from wormlike curling when heated)]

Caption: Scolecite (Rio Grande de Sol, Brazil) is one of the microporous, aluminosilicate minerals known as zeolites, commonly used as commercial absorbents and catalysts--including producing medical oxygen.
They were followed by acicular-fibrous zeolites such as natrolite/ gonnardite, thomsonite, mesolite and scolecite Analcime is usually a Na-rich mineral phase, but may sometimes contain appreciable K (Utada, 1970).
epistilbite, barrerite, scolecite, chabazite, "heulandite", wairakite, tetranatrolite and laumontite.
A number of other zeolites have also been reported from Merelani, including laumontite and mesolite in tufts of acicular white crystals, and stilbite, scolecite and chabazite-(Ca).
Powellite on Scolecite Nasik, India 6" wide (Powellite crystal 3" tall) ex-collection Joseph Freilich
Numerous dealers at this show, as at nearly all major shows these days, had superb specimens of (oh, let's see) Veracruz, Mexico amethyst; Moroccan vanadinite and cerussite; Pikes Peak, Colorado microcline (and even topaz); apophyllite, stilbite, calcite, scolecite, etc.
Yet even these great mesolite specimens are exceeded in size by several of the 100 scolecite specimens taken in January 2008 from a quarry near Junnar village.
Crocoite, scolecite, mesolite, cerussite--such specimens and other fragile delicacies are highly desired by avid mineral collectors.
The powellite crystals are loose, complete floaters, with white sprigs of scolecite protruding a millimeter or so here and there, and they are razor-sharp, textbook examples of tetragonal bipyramids, with c axes about 1.
Scolecite has been identified by petrographic means from locality 19 (Donald Hogarth, personal communication, 1993).
First, there are not-beautiful but very unusual specimens, found very recently in a well-digging near Aurangabad, of what some dealers at Denver were tentatively calling a mixture of scolecite and mesolite, but which has now been shown to be the zeolite species thomsonite.
