Optical Data of Götzenite
Type:
Biaxial (+)
RI values:
nα = 1.651 - 1.662 nβ = 1.653 - 1.665 nγ = 1.659 - 1.672
2V:
Measured: 38° to 74°, Calculated: 62° to 68°
Max. Birefringence:
δ = 0.008 - 0.010
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. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.
