Formula:

(K2,Ca,Na2,Sr,Mg)2[Al2Si4O12]2 · 12H2O

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. The suffix was added by the IMA in 1997 when chabazite (without suffix) was promoted to a series. It denotes the dominant extra-framework element.
