(K2,Ca,Na2,Sr,Mg)2[Al2Si4O12]2 · 12H2O
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. and its chemical composition.
The potassium dominant member of the Chabazite series of the Zeolite Group.
