1. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring
University essay from Stockholms universitet/Institutionen för geologiska vetenskaperAbstract : 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. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : 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. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania
University essay from Lunds universitet/Geologiska institutionenAbstract : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. READ MORE

4. A Geophysical Survey of Northern Utö
University essay from Stockholms universitet/Institutionen för geologiska vetenskaperAbstract : 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. READ MORE

5. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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. READ MORE
