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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sabine Rousku; [2021]
    Keywords : 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;

    Abstract : 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. 12. Kinetic interpretation of microstructures in the Gällivare area; implications for deformation phases and related metamorphic events.

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Linnéa Jansson Fagerlund; [2021]
    Keywords : Geology; Northern Sweden; Gällivare; Nautanen Deformation Zone; Fjällåsen Deformation Zone; Microstructures;

    Abstract : The goal of this study was to identify and describe different microstructures observed in samples from two major shear zones in the Gällivare area, namely the Nautanen Deformation Zone (NDZ), and the Fjällåsen deformation zone (FDZ). Thirteen samples were examined during this study. READ MORE

  4. 13. Carbon Storage in Quaternary Deposits of the Circum-Arctic Permafrost Region

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Annegret Udke; [2021]
    Keywords : Quaternary deposits; Carbon storage; Permafrost region; Organic Geochemistry; Sedimentology; Vulnerability; Thermokarst;

    Abstract : Rapid warming in northern latitudes will lead to permafrost thaw and subsequent carbon remobilisa­tion and release to the atmosphere. To incorporate the permafrost carbon climate feedback in globalEarth System Models, it is of importance to know the carbon stored in the circum­Arctic permafrostregion as accurate and precise as possible.
