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

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

   Sammanfattning : 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.

3. 7. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Laszlo Zorc; [2023-08-18]
   Nyckelord :;

   Sammanfattning : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. LÄS MER

4. 8. A Geophysical Survey of Northern Utö

   Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

   Författare :Nicole Flanders; [2023]
   Nyckelord :;

   Sammanfattning : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. LÄS MER

5. 9. Populism From Below : Mapping User-Centered Populist Content on TikTok

   Master-uppsats, Uppsala universitet/Medier och kommunikation

   Författare :Freja Ingelstam; [2023]
   Nyckelord :TikTok; Social Media; Media Logic; Affordance Theory; Political Communication; Populism; Regression Analysis;

   Sammanfattning : This thesis explores an understudied area in political communication research by examining populist communication on the social media platform TikTok. Specifically, the study focuses on content related to the Sweden Democrat party during the 2022 election. LÄS MER

7. 10. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Chun Hei Ho; [2023]
   Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

   Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER
