Bismuth carbonate mineral

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.[3] It crystallizes in the orthorhombic system and typically occurs as earthy to fibrous masses.[2]
