  1. 1. Isotropic and Anisotropic P and S Velocities of the Baltic Shield Mantle Results from Analyses of Teleseismic Body Waves

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tuna Eken; Roland Roberts; Uli Achauer; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teleseismic tomography; mantle lithosphere; seismic anisotropy; teleseismic earthquakes; shear wave splitting; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Geophysics Specialized In Seismology; geofysik; med inriktning mot seismologi;

    Abstract : The upper mantle structure of Swedish part of Baltic Shield with its isotropic and anisotropic seismic velocity characteristics is investigated using telesesismic body waves (i.e. P waves and shear waves) recorded by the Swedish National Seismological Network (SNSN). READ MORE

  2. 2. Strain quantifications in different tectonic scales using numerical modelling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lukas Fuchs; Hemin Koyi; Susanne Buiter; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Deformation modelling; progressive and finite deformation; salt tectonics; down-built diapir; upper mantle; lithosphere-asthenosphere boundary; seismic anisotropy; plate-mantle de coupling; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : 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. READ MORE

  4. 4. Metamorphism and Geochronology of the High Pressure Granulite and Upper Amphibolite Facies Rocks from the Southwest Swedish Granulite Region

    University dissertation from Lithosphere and Biosphere Science

    Author : Xiangdong Wang; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 40Ar 39Ar dating; Sm-Nd dating; Pb-Pb evaporation dating; conventional U-Pb dating; granulite facies metamorphism; P-T estimates; P-T-t path; the Southwest Swedish Granulite Region;

    Abstract : The present thesis presents pressure-temperature and geochronological data from the high-grade mafic rocks from the Southwest Swedish Granulite Region, which forms part of the southwestern Baltic Shield. The region is characterized by variably deformed and migmatized granitic to intermediate gneisses, metabasites and charnockites metamorphosed in granulite and upper amphibolite facies. READ MORE

  5. 5. New constraints on paleoreconstructions through geochronology of mafic dyke swarms in North Atlantic Craton

    University dissertation from Lund University, Faculty of Science, Department of Geology, Lithosphere and Biosphere Science

    Author : Mimmi Nilsson; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; baddeleyit; U-Pb; geokronologi; large igneous province; mantelplym; superkontinent; paleorekonstruktion; North Atlantic craton; baddeleyite; Large Igneous Province; Mantle plume; supercontinent; paleoreconstruction; U-Pb; geochronology; North Atlantic craton;

    Abstract : Earth history is punctuated by a series of events of supercontinent amalgamation and break-up. Fragments of old continents display rifted margins and orogenic sutures that testify their involvement in supercontinent cycles. READ MORE
