The Nussir copper deposit: petrology, mineralogy, geochemistry and distribution of ore mineralization

Abstract

The geology, petrography, mineralogy and geochemistry of the Nussir copper deposit in Finnmark, Northern Norway were studied during writing this thesis. The Nussir deposit of copper is a sedimentary-hosted hydrothermal deposit affected by low grade methamorphism and ductile deformation. The copper mineralization includes chalcopyrite, chalcocite, bornite, covellite, and digenite. The deposit contains also economically interesting trace elements, such as silver, gold, and PGE. The deposit shows a vertical zonation of ore minerals, accordingly from top to bottom: pyrite, chalcopyrite, silver minerals, galena→bornite→digenite, chalcocite, and covellite.
