| [Gr. (?) to boil +
-lite: cf. F. zéolithe.] (Min.) |
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.
