1. Assembly of the Caledonian Orogenic Wedge, Jämtland, Sweden
Sammanfattning : Collisional orogeny creates the largest mountain belts on Earth. The Caledonides of Scandinavia are a deeply eroded, ancient mountain belt, which today exposes a deep section through the former orogenic interior. LÄS MER
2. Testing Tectonic Concepts in the Seve Nappe Complex, Jämtland, Sweden
Sammanfattning : When continental plates collide, one of the involved continents is subducted beneath the other one. As a consequence, the lithosphere thickens along the convergent plate boundary and causes the formation of a mountain belt. LÄS MER
3. Precambrian and Caledonian history of Svalbard’s West Ny Friesland Terrane
Sammanfattning : This thesis deals mainly with age-investigations of metasedimentary and magmatic rocks of Ny Friesland, located in the northeastern Svalbard. However, the provenance of quartz-porphyry clasts in a Devonian conglomerate have also been investigated in northwestern Svalbard. LÄS MER
4. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile
Sammanfattning : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny. LÄS MER
5. Proterozoic to Quaternary Events of Fracture Mineralisation and Oxidation in SE Sweden
Sammanfattning : Fracture minerals and altered wall rock have been analysed to reveal the low-temperature evolution, especially regarding redox conditions, of the Simpevarp area, SE Sweden. This area is one of the two areas in Sweden investigated by the Swedish Nuclear fuel and Waste Management Co. LÄS MER
