  1. 1. Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ellinor Halvarsson; [2022]
    Nyckelord :Frontal wedge; deformation zone; Sveconorwegian orogeny; Sveconorwegian Orogen; Eastern Segment; shear-sense indicators; Protogine zone; structural geology; bedrock geology; Earth and Environmental Sciences;

    Sammanfattning : Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. LÄS MER

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

    Master-uppsats, Lunds universitet/Geologiska institutionen

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Geologiska institutionen

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

    Sammanfattning : 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.
