  4. 3. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Pieslinger; [2023]
    Keywords : ore geology; partial melting; quenching textures; symplectite; tellurides; critical metals;

    Abstract : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. READ MORE

  5. 4. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden
