Carrboydite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
[(Ni1-xAlx)(OH)2][SO4]x/2 · nH2O
(x<0.5, n>3x/2)
Colour:
Yellowish-green, blue-green
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.
