Optical Data of Szaibélyite
Type:
Biaxial (-)
RI values:
nα = 1.53 - 1.67 nβ = 1.53 - 1.73 nγ = 1.55 - 1.74
Max. Birefringence:
δ = 0.020 - 0.070
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.
