  1. 1. Geochronology of gneisses adjacent to the Mylonite Zone in southwestern Sweden: evidence of a tectonic window?

    University essay from Lunds universitet/Geologiska institutionen

    Author : James Davies; [2020]
    Keywords : Geochronology; Hallandian orogeny; Mylonite Zone; Sveconorwegian orogeny; U-Pb; Idefjorden terrane; Eastern Segment; B-Bulan; Brobacka; Earth and Environmental Sciences;

    Abstract : The relationship between the Eastern Segment and Idefjorden terrane prior to the Sveconorwegian orogeny has long been debated. Evidence of a common history is minimal and localised; at the same time, the notion that the Sveconorwegian orogeny formed as a result of a collisional event is also disputed. READ MORE

  2. 2. Metamorphic paragenesis and P-T conditions in garnet amphibolite from the Median Segment of the Idefjorden Terrane, Lilla Edet

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anna Sartell; [2019]
    Keywords : P-T conditions; Sveconorwegian orogeny; Idefjorden Terrane; Median Segment; Göta Älv Shear Zone; garnet amphibolite; upper amphibolite facies; partial melting; Earth and Environmental Sciences;

    Abstract : The Sveconorwegian orogeny (c. 1 Ga) lead to the recrystallization of large parts of southwestern Sweden, with widespread metamorphism as well as local migmatization. READ MORE

  3. 3. Zircon U-Pb constraints on the timing of Sveconorwegian migmatite formation in the Western and Median Segments of the Idefjorden terrane, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Mimmi Ingered; [2019]
    Keywords : Sveconorwegian orogen; U-Pb; Zircon; Migmatite; Idefjorden terrane; Earth and Environmental Sciences;

    Abstract : The Western and Median Segments of the Idefjorden terrane have been metamorphosed and migmatized during the Sveconorwegian orogeny (ca. 1 Ga), but the timing of these events between the two segments remains unclear. READ MORE

  4. 4. Garnet amphibolite in the internal Eastern Segment, Sveconorwegian Province : monitors of metamorphic recrystallization at high temperature and pressure during Sveconorwegian orogeny

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tove Hernnäs; [2018]
    Keywords : Sveconorwegian; metamorphic petrology; mapping; coronitic metagabbro; microtextures; Eastern Segment; Earth and Environmental Sciences;

    Abstract : The analyzed area exposes a deep underthrusting lower plate of the Sveconorwegian orogen and facilitates studying of an elsewhere hidden portion of the Earth. Petrographic and structural studies of different metamorphic rock types within the southern Eastern Segment, Sveconorwegian Province, Sweden, were carried out to better understand the regional metamorphism and deformation history.

  5. 5. P-T evolution of paragneisses and amphibolites from Romeleåsen, Scania, southernmost Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jan Ulmius; [2013]
    Keywords : Romeleåsen; metamorphism; geothermobarometry; pseudosection; Theriak-Domino; P-T path; Hallandian Danopolonian; Sveconorwegian Romeleåsen; metamorfism; geotermobarometri; pseudosektion; P-T-utveckling; halandisk danopolonisk; svekonorvegisk; Earth and Environmental Sciences;

    Abstract : Populärvetenskaplig sammanfattning Vad har berget i Romeleåsen varit med om? Jordskorpan är uppbyggd av ett antal plattor. Vid plattgränser under oceanerna bildas ny skorpa av magma som tränger upp. Oceanplattan kan inte öka i storlek. READ MORE
