Optical Data of ManganflurliteHide

Type:
Biaxial (-)
RI values:
nα = 1.623 nβ = 1.649(2) nγ = 1.673(2)
2V:
Measured: 86° (1)
Max. Birefringence:
δ = 0.050
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:
r > v, slight;
Pleochroism:
Visible
Comments:
X = pale yellow brown, Y = orange brown, Z = light yellow brown.
Comments:
α is calculated
