What is Chabazite?

Chabazite is a tectosilicate mineral series in the zeolite group, closely related to gmelinite, with the chemical formula M[Al2Si4O12]·6H2O, where M is one or more metal cations. Recognized minerals in the series include Chabazite-Ca, Chabazite-K, Chabazite-Na, and Chabazite-Sr, depending on the prominence of the indicated cation.
