The Zeolites are a group of related hydrous tectosilicate minerals, popular among collectors, that commonly occur in cavities in basic igneous rocks, especially vesicular basalt. They contain water in microscopic channels within a framework of aluminum silicate units; the water can be driven off (by heat) or replaced without altering the structure of the zeolite minerals. Zeolites include apophyllite, stilbite, heulandite, prehenite, scolecite, among others.
