1. Geophysical studies of the upper crust of the central Swedish Caledonides in relation to the COSC scientific drilling project
Abstract : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. READ MORE

2. Precambrian and Caledonian history of Svalbard’s West Ny Friesland Terrane
Abstract : 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. READ MORE

3. The Köli Nappe complex in Tännforsfältet western Jämtland, Swedish Caledonides
Abstract : This dissertation presents the Köli Nappe Complex of Tännforsfältet, an area of some 1200 km2 of volcano-sedimentary eugeoclinal rocks occurring in a shallow synformal basin, the Tännforsen Synform. The rocks have been metamorphosed under greenschist-lower amphibolite facies conditions. READ MORE

4. Crystal chemistry of Fe-Ti oxides in mafic rocks and metabasites: A study aimed at refinement of geological tools and interpretations
Abstract : This thesis consists of four subprojects: (A) ‘Clouding of plagioclase by Fe-Ti oxides’, (B) ‘Fe-Ti oxides during high-pressure metamorphism of mafic rocks’, (C) ‘Magnetic study of Fe-Ti oxides in mafic rocks and metabasites’, and (D) ‘Topotactic phase transitions in oxide minerals’. A) In southern Sweden dolerite dikes and gabbros with clouded plagioclase are common. READ MORE
