解釋/意思:

(n.) 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.

解釋/意思:

n. the common name of a large group of minerals often called the Zeolitic family—they are all soluble in acids and most of them gelatinise in acids in consequence of silica being set free.—adjs. Zeolit′ic; Zeolit′iform.
