  1. 21. Mineralogical characterization of gold in the Aurora ore zone in the Björkdal gold mine, northern Sweden – implications for metal recovery

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

    Author : Krister Åström; [2022]
    Keywords : geology; Björkdal gold deposit; Skellefte district; gold; Au; Aurora ore zone; metal recovery; cold mounting; SEM; QEMSCAN; mineral association; grain size;

    Abstract : The Aurora zone is an ore zone which was recently discovered in the Björkdal gold mine, northern Sweden, and it has been the main focus of mining and exploration activities for the past few years (Pressacco et al., 2020). The purpose of this project is to determine how gold occurs in the Aurora zone. READ MORE

  3. 22. THE MONASTERY HILL: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY IN LÖDÖSE, SW SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tobias Möhl; Fredrik Andersson; [2021-09-21]
    Keywords : Near-surface geophysics; Ground-penetrating radar; Resistivity; Magnetic gradiometry; 3D modeling; Archaeology; Leached clay; Medieval monastery; Sweden;

    Abstract : Even though Sweden has been one of the leading countries in the development of nearsurface geophysics instrumentation and practices, geophysical surveys in archaeology are not commonly used in Sweden. However, it is becoming increasingly popular, especially the use of ground-penetrating radar and metal detectors. READ MORE

  4. 23. LÖDÖSEHUS: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY AT THE SITE OF A MEDIEVAL CASTLE IN LÖDÖSE, SW SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Fredrik Andersson; Tobias Möhl; [2021-09-21]
    Keywords : Near-surface geophysics; Ground-penetrating radar; Resistivity; Induced Polarization; Archaeology; Leached clay; Medieval castle; Lödösehus; Lödöse; Sweden;

    Abstract : Near-surface geophysics is a well established method for mapping the geological conditions in the subsurface. The use of geophysics is also a commonly used method in archaeological surveys, although traditionally not as much in Sweden. READ MORE

  5. 24. The Structural Architecture of the Barsele Area, Sweden : Characterising the deformation events and mineralisation

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

    Author : Jaide Derbyshire; [2021]
    Keywords : Barsele; Structural Geology; Mineralisation; Deformation;

    Abstract : Located at an important intersect between orogenic Au deposits in Sweden’s Gold Line and volcanicmassive sulphide (VMS) deposits in the Skellefte Mining District, the Barsele area is of high interest.Currently, the Barsele deposit consists of the Norra VMS deposit and 3 intrusive-hosted orogenic Audeposits: Avan, Central, and Skiråsen which are hosted in a 1876 ± 10 Ma early orogenic granodiorite(Thomas, et al.
