Optical Data of StrontioperloffiteHide

This section is currently hidden. Click the show button to view.
Type:
Biaxial (-)
RI values:
nα = 1.805(4) nβ = 1.820(4) nγ = 1.829(4)
2V:
Calculated: 75°
Max. Birefringence:
δ = 0.024
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.

Surface Relief:
Moderate
