Add article description

Berzelianite is a rare copper selenide mineral with the formula Cu2Se.[2][3][4] It occurs as thin dendritic crusts or as fine-grained inclusions. It crystallizes in the isometric system,[5][6][7] unlike its dimorph, bellidoite, which crystallizes in the 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.
