  1. 1. Unraveling the Tectonic History of the Aurek Metagabbro within the Seve Nappe Complex, Scandinavian Caledonides

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sabine Rousku; [2021]
    Nyckelord :Scandinavian Caledonides; Seve Nappe Complex; Aurek metagabbro; Kebnekaise Mountains; Zircon U-Pb Geochronology; Thermodynamic modeling; Geochemistry; Skandinaviska Kaledoniderna; Seveskollan; Aurek metagabbro; Kebnekaisebergen; zirkon U-Pb geokronologi; Termodynamisk modellering; Geokemi;

    Sammanfattning : The Scandinavian Caledonides form a mountain range comprising nappe stacks of numerous far-travelled thrust sheets. The thrust sheets consist of diverse lithologies representing pre- and synorogenic sedimentary and igneous rocks subsequently metamorphosed to various degrees, from the Late Neoproterozoic to Middle Devonian.

  3. 2. Metamorphic microtextures and mineral assemblages in orthogneisses in NW Skåne – how do they correlate with technical properties?

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Maria Eleni Taxopoulou; [2020]
    Nyckelord :granitic gneiss; Eastern Segment; Söderåsen; rock quality; quantitative analyses; grain size; aspect ratio; circularity; mineralogy; Earth and Environmental Sciences;

    Sammanfattning : Glacifluviala avlagringar har varit de vanligaste källorna för byggmaterial i Sverige under de senaste decennierna. De är dock ändliga resurser som måste bevaras eftersom de också fungerar som akvifärer. LÄS MER

  4. 3. 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.

  5. 4. Qualitative and quantitative petrography of meta-mafic rocks at Ölme, in the Eastern Segment of the Sveconorwegian orogen

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Diana Carlsson; [2015]
    Nyckelord :metamorphism; high pressure; amphibolite; granulite; gabbro; metagabbro; garnet-amphibolite; complex coronitic textures; symplectite; Eastern Segment; Transitional section;

    Sammanfattning : Meta-mafic intrusions with an intrusion age of 1.6-0.9 Ga are found along a north-south trend in theTransitional section of the Eastern Segment in Sweden. These intrusions are garnet-bearing and thus anexception to other meta-mafic intrusions found in Sweden. LÄS MER

  7. 5. Metamorphosed and partially molten hydrothermal alteration zones of the Akulleq glacier area, Paamut gold province, South-West Greenland

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Magnus Asiboh Tebi; [2011]
    Nyckelord :remobilized gold; South-West Greenland; Paamiut gold province; hydrothermal alteration; sulfide; Paamiut guldprovins; sydvästra Grönland; hydrotermal omvandling; sulfid; Earth and Environmental Sciences;

    Sammanfattning : Området kring akulleqglaciären ligger i närheten av bosättningen Paamiut, sydvästra Grönland. Tonalit- trondhjemit och granodioritgnejser (TTG) utgör huvudlitologin i området. Inom TTG-gnejserna återfinns ett cirka 1 km brett hästskoformat bälte av suprakrustala bergarter. LÄS MER
