About CalciocatapleiiteHide

Formula:
CaZr(Si3O9) · 2H2O
Colour:
Pale yellow to cream
Lustre:
Vitreous, Dull
Hardness:
4½ - 5

Colour:
Pale yellow to cream

Optical Data of CalciocatapleiiteHide

Type:
Uniaxial (+)
RI values:
nω = 1.603 nε = 1.639
Max. Birefringence:
δ = 0.036
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
