Berzelianite is a rare

tetragonal system.[8]
The crystals are opaque and slightly malleable.

Occurrence and name

Berzelianite was first identified at the Skrikerum Mine (also spelled as Skrickerum Mine) in Valdemarsvik, Östergötland, Sweden in 1850.[6]

It was named by James Dwight Dana to honor Jöns Jakob Berzelius, a Swedish chemist who is seen as the father of analytical chemistry. He invented chemical symbol notation and discovered the elements cerium, selenium, silicon, and thorium.[6]

Berzelianite often occurs together with eucairite, clausthalite, tiemannite, umangite, klockmannite, aguilarite, crookesite, athabascaite, stromeyerite, polybasite, pearceite, gold, uraninite, pyrite, marcasite, calcite.
