Chabazite-lévyne subgroup

Chabazite () is a tectosilicate mineral series in the zeolite group, closely related to gmelinite, with the chemical formula , 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.

Lévyne or lévynite is a group of zeolite minerals, i.e. hydrated silicate minerals. There are two members of the group: Lévyne-Na, the sodium-dominant species , and Lévyne-Ca the calcium-dominant species
