21. 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.

22. Sveconorwegian orogenesis in the southwestern Baltic Shield - Zircon geochronology and tectonothermal setting of orthogneisses in SW Sweden
Abstract : The Mylonite zone (MZ) is a prominent late-Sveconorwegian lithological terrane boundary in the SW Baltic Shield along which large-scale crustal block movements took place during the Sveconorwegian orogeny. The southern section of the MZ also defines a conspicuous metamorphic break separating upper amphibolite and high-pressure granulite facies rocks in the parautochthonous Eastern Segment (ES), from middle amphibolite facies rocks in the overlying Western Segment (WS).

23. Electrical Characterization of Integrated InAs Nano-Structures
Abstract : This thesis analyzes the electrical properties of InAs nano-structures, that are integrated into different materials and geometries. The thesis describes integration related issues of InAs, the epitaxial synthesis of the InAs nano-structures and summarizes experimental techniques for analysis of electrical properties of the integrated structures.

24. Origin of massive sulfide ores in the Skellefte district, as indicated by fluid inclusions
Abstract : The Proterozoic SkeUefte massive sulfide ore district is confined to a 200 km long belt of a submarine metavolcanic and metasedimentary rock sequence in northern Sweden. It is located between an area of terrestrial metavolcanics in the north and gneisses, migmatites and granites in the south. READ MORE

25. Understanding Zircon Geochronology - Constraints from Imaging and Trace Elements
Abstract : Formation of incipient charnockite in Söndrum, SW Sweden and the Kerala Khondalite Belt (KKB), S. India is accompanied by zircon growth. The age of the dehydration event is constrained by dating newly formed zircon to 1397±4 Ma (2?, MSWD=1.7) in Söndrum and ca. READ MORE
