  1. 1. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : William Crang; [2024]
    Keywords : methane; hydrothermal fluids; fluid-rock interaction; impact craters; reduction haloes; pyrite preservation; Siljan Ring;

    Abstract : The Siljan Ring in Dalarna, Sweden is the site of the largest meteor impact crater in Europe and has long been a topic of discussion regarding methane production. However, the source of this methane and the timing of production in relation to the impact remain unclear. READ MORE

  2. 2. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ellen Svens; [2024]
    Keywords : Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

    Abstract : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.
