Glory Hole

Carr Boyd Rocks Ni mine, Menangina Station, Menzies Shire, Western Australia, Australia
Formula:
(Ni1-xAlx)(SO4)x/2(OH)2 · nH2O
(x<0.5, n>3x/2)
Colour:
Yellowish-green, blue-green
Lustre:
Waxy, Dull
Specific Gravity:
2.50
Crystal System:
Hexagonal
Name:
Named for the Carr Boyd nickel mine, Australia, the type locality.
As part of the recent re-evaluation of the nomenclature of the hydrotalcite supergroup (Mills et al., 2012), carrboydite was identified as a questionable species which needs further investigation.

Optical Data of CarrboyditeHide

Type:
Uniaxial (-)
RI values:
nω = 1.56 nε = 1.54
Max. Birefringence:
δ = 0.020
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
Comments:
may be biaxial (–)
