1. Metamorphism in the roots of mountain belts and its effect on rock technical properties : A case study of the Eastern Segment, Sveconorwegian orogen
Abstract : Deciphering the metamorphic evolution of the roots of mountain belts is essential for understanding deep tectonic processes involved in mountain building. The Sveconorwegian orogen in southwestern Scandinavia, formed during the Rodinia assembly in the transition between the Mesoproterozoic and Neoproterozoic Eras, has been exhumed and provides access to interior deep structural levels of the ancient mountain belt.

2. How do fluids move through rocks? : High fluxes of CO2 in the Earth's crust
Abstract : Metamorphic hydrous, CO2-bearing fluids play a critical role in the global carbon cycle. However, how big this influence is on the global carbon cycle and therefore on global climatic processes, is unknown. The actual amount of CO2 which is released into the atmosphere due to metamorphic processes is still debated. READ MORE

3. How do metamorphic fluids move through rocks? : An investigation of timescales, infiltration mechanisms and mineralogical controls
Abstract : This thesis aims to provide a better understanding of the role of mountain building in the carbon cycle. The amount of CO2 released into the atmosphere due to metamorphic processes is largely unknown. READ MORE

4. Metamorphic zircon formation in gabbroic rocks – the tale of microtextures
Abstract : Dating of metamorphic events is crucial for the understanding and reconstruction of large-scale geological processes such as orogenesis. Zircon is one of the most commonly used minerals for dating of igneous and metamorphic events. Zircon incorporates uranium and excludes lead during crystallization, and with time the uranium decays to lead. READ MORE
