Colour:
Colourless
Lustre:
Vitreous
Hardness:
4
Crystal System:

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.

Type:
Biaxial (+/-)
RI values:
nα = 1.478 - 1.485 nβ = 1.48 - 1.4895 nγ = 1.48 - 1.49
Max. Birefringence:
δ = 0.002 - 0.005
Based on recorded range of RI values above.
Based on recorded range of RI values above.
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.
