Name:
Named in 1827 by Pierre Berthier for the type locality thought to be at Nontron, Dordogne, France. Actually, the type locality is at Le Manderau, Saint-Pardoux-la-Rivière, not far from Nontron. Originally named "chloropal" in 1822 by Dr. Johann Jakob Bernhardi and Dr. Rudolph Brandes for chlor- and opal suggesting it was a green waxy mineral somewhat resembling common opal.

Optical Data of NontroniteHide

This section is currently hidden. Click the show button to view.
Type:
Biaxial (-)
RI values:
nα = 1.567 - 1.600 nβ = 1.604 - 1.632 nγ = 1.605 - 1.643
2V:
Measured: 25° to 68°, Calculated: 32° to 46°
Max. Birefringence:
δ = 0.038 - 0.043
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
Dispersion:
r > v strong
