Optical Data of Cervandonite-(Ce)Hide

Type:

Biaxial

RI values:

n_α = 1.99 n_γ = 2

Max. Birefringence:

δ = 0.010
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.

Thickness: 30 µm

Rotation:

Surface Relief:

Moderate

Dispersion:

r > v

Comments:

Refractive indices are ~1.99 parallel to a direction in which the grain is yellowish, reddish brown, and ~2.0 where black.
