03946680015794806892993.jpg
Thomas Hodge-Smith
Formula:
(Cu,Zn)6Zn(SO4)2(OH)10·3H2O
Crystal System:
Trigonal
Name:
Named in honor of Thomas Hodge-Smith (27 October 1894, Swindon, Wiltshire, England - 8 June 1945), mineralogist and curator of the Australian Museum, Sydney, Australia.

Closely related to schulenbergite (also trigonal), having one of seven Cu-dominated sites replaced with single Zn-dominated one. Also chemically related to ktenasite and christelite. Compare 'UM1992-30-SO:CCuHZn', the Zn analogue of schulenbergite, 'Unnamed Cu-Zn Sulphate (of Schmutz et al.)', and bechererite.


The species is reported to have an interesting, unique "decorated, interrupted-sheet structure".
