Unnamed (Co-analogue of Ktenasite)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Co(Cu,Co)4(SO4)2(OH)6 · 6H2O
Isostructural with:
A Zn-free, Co-dominant analogue of ktenasite, confirmed by a crystal-structure refinement (U. Kolitsch, to be published). The Co-rich solid solution member described by Sarp et al. (1990), with Co>Ni>Zn may be the same species.

A joint proposal on the nomenclature of ktenasite-type minerals is in preparation (Leverett et al., 2009-2012).
