About KipushiteHide

Formula:
(Cu,Zn)5Zn(PO4)2(OH)6 · H2O
Colour:
Emerald green
Lustre:
Vitreous
Hardness:
4
Specific Gravity:
3.8
Crystal System:
Monoclinic
Name:
Named in 1985 by Paul Piret, Michel Deliens and Jacqueline Piret Meunier, after the type locality at the Kipushi Mine (Prince Léopold Mine), Kipushi, Lubumbashi (Elizabethville), Katanga (Shaba), Congo (Zaïre).
The phosphate analogue of philipsburgite. Chemically related to veszelyite and zincolibethenite.

Not to be confused by Kipushite (of Buttgenbach) (a synonym of veszelyite).

The Zn site, of tetrahedral coordination, in the kipushite-philipsburgite solid solution is Zn-deficient, with Cu substituting for Zn.
