Optical Data of DoyleiteHide

This section is currently hidden. Click the show button to view.
Type:
Biaxial (+)
RI values:
nα = 1.545(1) nβ = 1.553(1) nγ = 1.566(1)
2V:
Measured: 77° , Calculated: 78°
Max. Birefringence:
δ = 0.021
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.

Surface Relief:
Moderate
Dispersion:
None. Type description gives strong, r > v.
