Name:
Named by P. Kokkoros in 1950 after Konstantinos I. Ktenas (1884-1935), Greek physician, professor of mineralogy and petrology (since 1908) and Dean (1918) of the National and Kapodistrian University of Athens, Director of the Museum of Mineralogy and Paleontology and of the Zoological Museum of the University (1918), Head of the Greek Geological Survey and one of the founding members of the Academy of Athens (1926).


Rare secondary copper-zinc sulphate with typical pseudo-orthorhombic habit.
Mg- or Cd-bearing varieties are also known (U. Kolitsch & G. Giester, unpublished results), as well as a Zn-dominant analogue (Unnamed (Zn-analogue of Ktenasite) ) and a Zn-free, Co-dominant analogue (Unnamed (Co-analogue of ktenasite)).

Ktenasite may have to be split up into a Cu- and a Zn-dominant species; the crystal structure contains a Zn site, a Cu site and a mixed Cu/Zn site with variable occupancy (U. Kolitsch & G. Giester, unpublished results). Data of Livingstone (1991) suggest dominant Zn on at least two sites, although this suggestion is based only on chemical analyses.
A joint proposal on the nomenclature of ktenasite-type minerals is in preparation (Leverett et al., 2009-2011).
