Zincobriartite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Cu2(Zn,Fe)(Ge,Ga)S4
Crystal System:
Tetragonal
Member of:
Zn analogue of briartite.

Unique combination of elements - the only approved Cu-Zn-Ge mineral.

The phase of the above composition, apparently from Kipushi mine, was codified as UM1965-10-S:CuFeGeZn.
