Hermannjahnite

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.

[2][3] Hermannjahnite is a zinc-analogue of dravertite – another mineral from prolific Tolbachik.

[4] Minerals somewhat chemically similar to hermannjahnite include ktenasite and christelite.
