Optical Data of FerrokentbrooksiteHide

Type:
Uniaxial (-)
RI values:
nω = 1.6221 nε = 1.6186
Max. Birefringence:
δ = 0.004
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.

Surface Relief:
Moderate
Pleochroism:
Non-pleochroic
Comments:
no pleochroism at maximum birefringence
