Description
A bronze-like mineral composed of iron sulfide. Pyrrhotite is slightly magnetic and tarnishes with time. It occurs near pyrite (Iron disulfide), Chaclopyrite, or Magnetite deposits. Pyrrhotite has been found in Rumania (Kisbanya), Austria, Italy (Trentino), Germany (Saxony, Bavaria, Andreas-Berg), Switzerland, Norway (Kongsberg), Sweden, Brazil, Canada (Bristish Columbia, Ontario), Mexico (Chihuahua) and the U.S. (Maine, Connecticut, New York, Pennsylvania, Tennessee, California).
