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.
The sodium-dominant member of the Chabazite series of the Zeolite Group.
Formerly called herschelite.
Formerly called herschelite.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.
