Optical Data of BruciteHide

Type:
Uniaxial (+)
RI values:
nω = 1.56 - 1.59 nε = 1.58 - 1.6
Max. Birefringence:
δ = 0.010 - 0.020
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 ยตm 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.

Surface Relief:
Moderate
Comments:
Anomalously biaxial.
