Hermannjahnite is a rare sulfate mineral with the relatively simple formula CuZn(SO4)2. It is one of many fumarolic minerals discovered on the Tolbachik volcano.

Relation to other minerals

Hermannjahnite is a zinc-analogue of dravertite – another mineral from prolific Tolbachik. Minerals somewhat chemically similar to hermannjahnite include ktenasite and christelite.
