Bieberite

Bieberite

Named for the type locality at the Im Lochborn copper mine in Bieber, Hesse, Germany. Bieberite is a rare to uncommon mineral that has additional localities in England, Spain, France, Australia, Zimbabwe, the United States, and Chile, among several others. It occurs as an oxidation product of colbalt-bearing sulfide arsenates in association with erythrite, annabergite, pharmacolite, cobaltite, and linnaeite. Bieberite is soluble in water and additionally will easily dehydrate to the hexahydrate moorhouseite.
