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.[1][2]

Relation to other minerals

Hermannjahnite is a zinc-analogue of dravertite - another mineral from prolific Tolbachik.[3] Minerals somewhat chemically similar to hermannjahnite include ktenasite and christelite.[4][5]
