ZEOLITE
Ze"o*lite, n. Etym: [Gr. -lite: cf. F. zéolithe.] (Min.)
Definition: A term now used to designate any one of a family of minerals,
hydrous silicates of alumina, with lime, soda, potash, or rarely
baryta. Here are included natrolite, stilbite, analcime, chabazite,
thomsonite, heulandite, and others. These species occur of secondary
origin in the cavities of amygdaloid, basalt, and lava, also, less
frequently, in granite and gneiss. So called because many of these
species intumesce before the blowpipe. Needle zeolite, needlestone;
natrolite.
