Optical Data of KorneliteHide

This section is currently hidden. Click the show button to view.
Type:
Biaxial (+)
RI values:
nα = 1.572 nβ = 1.586 nγ = 1.64
2V:
Measured: 49° to 62°, Calculated: 56°
Max. Birefringence:
δ = 0.068
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:
very weak r>v
