Optical Data of Parthéite
Type:

RI values:
nα = 1.547 - 1.55 nβ = 1.549 - 1.552 nγ = 1.559 - 1.565
2V:
Measured: 45° to 48°, Calculated: 50°
Max. Birefringence:
δ = 0.012 - 0.015
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.
