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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER

  2. 2. Comparison of Magnetic-Susceptibility Models From UAV-borne and Ground Measurements in Enåsen Area, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Clara Sjödin; [2022]
    Nyckelord :magnetic susceptibility; Enåsen area; UAV survey; magnetic anomalies; Potent; magnetisk susceptibilitet; Enåsen; drönare; magnetiska anomalier; Potent;

    Sammanfattning : Mapping anomalies in the Earth’s magnetic field is one method used in applied geophysics, for exploring buried structures and objects. Magnetic surveys can be ground-based or made airborne, onboard airplanes, helicopters, or unmanned aerial vehicles (UAV), also known as drones. LÄS MER

  3. 3. Metamorfos och malmbildning i Enåsens guldgruva Hälsingland

    Kandidat-uppsats, Uppsala universitet/Geologiska institutionen

    Författare :Stefan Sädbom; [1987]
    Nyckelord :;

    Sammanfattning : Some parts of the mineralogy and the petrology of the Enåsen gold-deposit, northern Hälsingland, Sweden are described. The gold in Enåsen is extracted from a sillimanite-rich quartzite. The rocks in the stratigraphic foot-wall of the ore are described as a part of a stratigraphic column. LÄS MER
