Gunningite is one of the minerals in the Kieserite group, with the chemical formula (Zn,Mn2+)SO4·H2O. Its name honours Henry Cecil Gunning (1901–1991) of the Geological Survey of Canada and a professor at the University of British Columbia. [3]
Occurrence
Gunningite is rare. It is found in dry areas of the oxidized portions of sphalerite-bearing deposits. It has been noted in mines in Canada ( Yukon Territory, British Columbia and New Brunswick), the United States ( Nevada and Arizona), Switzerland ( Valais), Greece, Attica and Germany ( Baden-Württemberg).
