A copper-zinc mineralization in Trolldalen, Lofoten, Northern Norway.
From the previous it is most likely that even separated the various mineralizations in Trolldalen are related and contemporary. Allthough different minerals appear in the different veins, pyrrhotite, chalcopyrite and sphalerite are always present. It may also be noted that pyrite, a very common mine...
