    • Biogeochemical impact of historical submarine mine tailings on benthic ecosystems in the Repparfjord (Northern Norway) 

      Hoff, Marie; Argentino, Claudio; Huljek, Laura; Fiket, Zeljka; Mun, Yulia; Barrenechea Angeles, Inés; Strmic Palinkas, Sabina; Panieri, Giuliana (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-08)
      Historical copper mine tailings deposited in the Repparfjord, Northern Norway, provided new insight into the biogeochemical impact of submarine tailings disposals on high-latitude coastal ecosystems. The submarine tailings disposal in the Repparfjord represents a product of mining activities between 1972 and 1979. Their environmental impact has been extensively studied during the last decade, but ...

    • Evolution of metal-bearing fluids at the Nussir and Ulveryggen sediment-hosted Cu deposits, Repparfjord Tectonic Window, northern Norway 

      Mun, Yulia; Strmic Palinkas, Sabina; Kullerud, Kåre; Nilsen, Kjell S.; Neufeld, Kai; Bekker, Andrey (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-13)
      The Palaeoproterozoic greenstone belts of Fennoscandia are metamorphosed and deformed volcanic and sedimentary rocks that formed in basins with a high base-metal ore potential. One of these, the Repparfjord Tectonic Window (RTW), is exposed in the Caledonides of northern Norway and contains several sediment-hosted Cu deposits including Nussir and Ulveryggen. The RTW is composed of mafic metavolcanic ...

    • Geochemistry of sediment-hosted copper deposits and their environmental impact: A case study from the Nussir and Ulveryggen deposits, Repparfjord Tectonic Window, Northern Norway 

      Mun, Yulia (Doctoral thesis; Doktorgradsavhandling, 2019-11-07)
      Modern growing economy and technology require metals. Therefore mining is an unavoidable process. Mining in its turn results in the production of large amounts of mine waste. This research is focused on one type of mine waste, mine tailings, formed after the processing of Cu-sulphides deposits. Acid mine drainage (AMD) is a consequence of the oxidation of sulphide-rich rocks and has a drastic impact ...

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

      Mun, Yulia (Master thesis; Mastergradsoppgave, 2013-06-28)
      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 ...

    • The Role of Mineral Assemblages in the Environmental Impact of Cu-Sulfide Deposits: A Case Study from Norway 

      Mun, Yulia; Palinkas, Sabina Strmic; Kullerud, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-12)
      Metallic mineral deposits represent natural geochemical anomalies of economically valuable commodities but, at the same time, their weathering may have negative environmental implications. Cu-sulfide mineral deposits have been recognized as deposits with a particularly large environmental footprint. However, different Cu deposits may result in significantly different environmental impacts, mostly ...

    • Stability of Cu-Sulfides in Submarine Tailing Disposals: A Case Study from Repparfjorden, Northern Norway 

      Mun, Yulia; Strmic Palinkas, Sabina; Forwick, Matthias; Junttila, Juho; Pedersen, Kristine Bondo; Sternal, Beata; Neufeld, Kai; Tibljaš, Darko; Kullerud, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-13)
      Mine tailings that were produced during the exploitation of the Ulveryggen siliciclastic sediment-hosted Cu deposit in northern Norway were disposed into the inner part of Repparfjorden from 1972 to 1978/1979. This study focuses on the mineralogy and geochemistry of the submarine mine tailings and underlying natural marine sediments from the inner part of Repparfjorden, as well as on the primary ...
