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

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

3. 2. Zircon U-Pb constraints on the timing of Sveconorwegian migmatite formation in the Western and Median Segments of the Idefjorden terrane, SW Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Mimmi Ingered; [2019]
   Keywords : Sveconorwegian orogen; U-Pb; Zircon; Migmatite; Idefjorden terrane; Earth and Environmental Sciences;

   Abstract : The Western and Median Segments of the Idefjorden terrane have been metamorphosed and migmatized during the Sveconorwegian orogeny (ca. 1 Ga), but the timing of these events between the two segments remains unclear. READ MORE

4. 3. Metamorphic record of monazite in aluminous migmatitic gneisses at Stensjöstrand, Sveconorwegian orogen

   University essay from Lunds universitet/Geologiska institutionen

   Author : Andreas Olsson; [2016]
   Keywords : Monazite; LA-ICP-MS; U-Th-Pb Geochronology; Migmatite; Stensjöstrand; Earth and Environmental Sciences;

   Abstract : Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) has been utilised to investigate the age and chemical composition of two texturally different types of monazite in leucosome and mesosome of polymetamorphic aluminous migmatitic gneisses at Stensjöstrand, Halland. Results of radiometric dating are compared with previously published zircon dates. READ MORE

5. 4. Small-Scale Shear Zones and Deformation in Migmatite on Mt. Åreskutan

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Johanna Gottlander; [2015]
   Keywords : Shear zone; migmatite; Åreskutan; deformation; garnet;

   Abstract : The Åreskutan nappe complex consists of the partly molten rock migmatite, which originates from the subduction formed by the collision of continents Baltica and Laurentia. It is a so-called hot nappe, which has been deeply buried in the subduction zone, based on findings of high-pressure minerals in the migmatitic gneiss. READ MORE

6. 5. Monazite in metasediments from Stensjöstrand : a pilot study

   University essay from Lunds universitet/Geologiska institutionen

   Author : Andreas Olsson; [2013]
   Keywords : pilot study monazit; Stensjöstrand; Sveconorwegian orogen; monazite; metasediments; metasediment; Sveconorvegiska orogenesen; pilotstudie; Earth and Environmental Sciences;

   Abstract : Monazit är ett Ree– och Th-bärande fosfatmineral som förekommer i vissa magmatiska och metamorfa bergarter. Mineralet är användbart för datering av den metamorfa utvecklingen och kan bidra till att yt-terligare karaktärisera metamorfosen i en bergart, detta genom att man undersöker zoneringar i kristallerna.
