About GillarditeHide

Crystal System:
Member of:
Named in 2007 by David M. Colchester, Peter Leverett, Meagan E. Clissold, Peter A. Williams, David E. Hibbs and Ernest H. Nickel in honour of Robert D. Gillard (23 August, 1936, London, England - ) professor, Department of Chemistry, Cardiff University, Wales, in recognition of his contributions to the field of inorganic chemistry.
Isostructural with:
Atacamite Group.
Closely related to paratacamite.

The Ni analogue of herbertsmithite and leverettite.

At least some of the gillardite from the type locality was originally considered to be "Ni-bearing paratacamite".

Approval Year:

D : Oxyhalides, hydroxyhalides and related double halides
A : With Cu, etc., without Pb

1 : A2(O,OH)3Xq
