Physical Properties of Zincalstibite
Optical Data of Zincalstibite
Type:
Uniaxial (-)
RI values:
nω = 1.647(2) nε = 1.626(2)
Max. Birefringence:
δ = 0.021
Based on recorded range of RI values above.
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.
