Bismutite

Bismutite or bismuthite is a bismuth carbonate mineral with formula Bi₂(CO₃)O₂ (bismuth subcarbonate). Bismutite occurs as an oxidation product of other bismuth minerals such as bismuthinite and native bismuth in hydrothermal veins and pegmatites.[1] It crystallizes in the orthorhombic system and typically occurs as earthy to fibrous masses.[2]

It was first described in 1841 for an occurrence in Saxony.[2]
