1. Ages, origins and metamorphic histories of some major nappe units in the southern Swedish Caledonides
Sammanfattning : .... LÄS MER
2. Performance in the Swedish Building Code : An Inquiry into the Consequences for Architectural Design of the Formulation and Assessment of Performance Requirements
Sammanfattning : This thesis investigates performance-based regulation in Sweden and its consequences for architectural design. In the last 50 years, there has been a transition from prescriptive to performance-based regulation, propelled by the drive to further innovation, productivity and competitiveness by expressing the functions expected of the buildings as performances.

3. Characterising volcanic magma plumbing systems : A tool to improve eruption forecasting at hazardous volcanoes
Sammanfattning : This thesis attempts to develop our understanding of volcanic magma plumbing systems and the magmatic processes that operate within them, such as fractional crystallisation, crustal partial melting, assimilation, and magma mixing. I utilise petrology, rock and mineral geochemistry, and isotope systematics to seek to improve our ability to forecast the eruptive frequency and style of active volcanoes, an aspect often lacking in current volcano monitoring efforts.

4. Magma plumbing architecture in Indonesia and the North Atlantic Igneous Province
Sammanfattning : Magma plumbing systems represent the physical framework of magma transport and storage from the source region in the mantle, through the crust, until reaching the surface in a volcanic eruption. Characterising the different aspects of magma plumbing, in particular the distribution of magma storage zones throughout the crust, is of key importance to better understand the behaviour of individual volcanoes.

5. Strain quantifications in different tectonic scales using numerical modelling
Sammanfattning : This thesis focuses on calculation of finite and progressive deformation in different tectonic scales using 2D numerical models with application to natural cases. Essentially, two major tectonic areas have been covered: a) salt tectonics and b) upper mantle deformation due to interaction between the lithosphere and asthenosphere. LÄS MER
