Associated minerals are: berzelianite
, bellidoite, cadmoseite (mercurian and cuprian), chameanite, crookesite, eskebornite, eucairite, ferroselite, hakite, klockmannite, a luanheite-type phase, trogtalite-krutaite, tiemannite, tyrellite, umangite and uraninite.
From the type locality of the copper selenide berzelianite
, Skrikerum in southeastern Sweden, several selenium-bearing minerals have been newly identified: athabascaite, bukovite, umangite and chalcomenite are the additional phases.
Berzelius himself later presented specimens of berzelianite
, yttrocerite and other recently discovered Swedish minerals from his collection to the British Museum in 1817, and sent a great many specimens over a 30-year period to Hauy in Paris.
