It is a member of the autunite group. The associated mineral metazeunerite is a dehydration product of zeunerite.
Zeunerite occurs as a secondary mineral in the oxidized weathering zone of hydrothermal uranium ore deposits which contain arsenic. Olivenite, mansfieldite, scorodite, azurite and malachite are found in association with zeunerite.<ref name=Handbook/>
It was first described in 1872 for an occurrence in the Schneeberg District, Ore Mountains, Saxony, Germany. It was named for Gustav Anton Zeuner (1828–1907).<ref name=Mindat/>
