Optical Data of LunijianlaiteHide

Type:
Biaxial (-)
RI values:
nα = 1.576(5) nβ = 1.582(5) nγ = 1.587(5)
2V:
Measured: 60° (5), Calculated: 72°
Max. Birefringence:
δ = 0.011
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
Dispersion:
very weak
