It forms a solid solution series with galena PbS. OccurrenceIt occurs in low-sulfur hydrothermal deposits with other selenides and in mercury deposits. It is associated with tiemannite, klockmannite, berzelianite, umangite, gold, stibiopalladinite and uraninite.[2] It was first described in 1832 and named for the discovery locality of Clausthal-Zellerfeld in the Harz Mountains, Germany.[4] See also{{Portal|Earth sciences}}
