Volborthite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Cu3(V2O7)(OH)2 · 2H2O
System:
Monoclinic
Colour:
Olive-green, ...
Hardness:
Name:
Named after Alexander von Volborth (1800-1876), Russian paleontologist, who first noted the mineral.
A secondary mineral found in the oxidized zones of vanadium-bearing hydrothermal deposits.

At least two different monoclinic space-group variants (C2/m, C2/c) seem to be stable at ambient temperature.

Visually similar to vésigniéite.
Structurally related to engelhauptite.
