About KapellasiteHide

Formula:
Cu3Zn(OH)6Cl2
Crystal System:
Trigonal
Member of:
Name:
Named after Christo Kapellas (1938-2004), collector and mineral dealer of Kamariza, Lavrion, Greece.
Isostructural with:
A metastable polymorph of herbertsmithite. Has been confused with botallackite ("Zn-bearing botallackite"; Wendel et al., 1999); both are visually very similar.
Also known as a synthetic compound (phase IIα of Feitknecht and Maget, 1949).

The Mg analogue of kapellasite is called haydeeite.
