    • Late Palaeozoic fault-controlled hydrothermal Cu–Zn mineralisation on Vanna island, West Troms Basement Complex, northern Norway 

      Paulsen, Hanne-Kristin; Bergh, Steffen G; Strmic Palinkas, Sabina (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-31)
      The Vannareid–Burøysund fault is a major, brittle, normal fault in northern Norway, with cohesive fault rocks (cataclasites) that host Cu–Zn-bearing quartz-carbonate veins. The fault is exposed on the island of Vanna in the Neoarchaean to Palaeoproterozoic West Troms Basement Complex, separating variably deformed tonalitic gneisses in the footwall from mylonitised metasedimentary rocks and tonalites ...

    • Palaeoproterozoic foreland fold-thrust belt structures and lateral faults in the West Troms Basement Complex, northern Norway, and their relation to inverted metasedimentary sequences 

      Paulsen, Hanne-Kristin; Bergh, Steffen G; Palinkas, Sabina Strmic; Karlsen, Siri; Kolsum, Sofie; Rønningen, Ida Ulvik; Armitage, Paul E.B.; Nasuti, Aziz (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-15)
      Palaeoproterozoic fold-thrust belt structures and steep, lateral shear zones characterize the foreland deformation of Neoarchaean basement tonalites in Vanna, West Troms Basement Complex, northern Norway. Low-grade par-autochthonous and allochthonous cover units (2.4–2.2. Ga) with sandstones and calcareous metapelites exist in separate areas of the foreland. They were formed as intracontinental rift- ...

    • Structurally controlled hydrothermal mineralization: A case study from Vanna island, northern Norway 

      Paulsen, Hanne-Kristin (Doctoral thesis; Doktorgradsavhandling, 2020-02-27)
      The formation of metal and mineral deposits is closely related to the tectonic setting in which they form. Structures create avenues of net permeability that allow ore-bearing fluids to transport and deposit mineralization. In a deeper crustal setting these structures can be ductile shear zones, while brittle faults and fractures are the dominant fluid pathways in the upper continental crust. This ...
