Name: Named in 1788 by Louis-Augustin Bosc d’Antic from the Greek chabazios, tune or melody, one of twenty stones named in the poem Peri lithos, which extolled the virtues of minerals. The poem is ascribed to Orpheus, legendary founder of the Orphic cult, which flourished in Greece in the early centuries.

Synonym of: Chabazite-Ca, Chabazite-K, Chabazite-Mg, Chabazite-Na, Chabazite-Sr. According to the current nomenclature for zeolite minerals, chabazite is the name of a series of closely related minerals. Chemical analysis is required to distinguish between them. The calcium-dominant member of the Chabazite series is the most common member of this series.
