  1. 1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Chun Hei Ho; [2023]
    Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER

  3. 2. Future Imaginaries of Negative Emission Technologies and Folklore Myths in Icelandic Basalt: Provisional Order Emerges from the Possible Magma in the Age of ‘Hauntology’ and Broken Time

    Master-uppsats, Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

    Författare :Rikke Jespersen; [2023]
    Nyckelord :NETs; Desire; Green Capitalism; Imaginaries; Storytelling; Pluriverse; Social Sciences;

    Sammanfattning : Why do we in the Western part of world today tend to believe in technology’s mythical promises rather than in folklore myths? Imaginaries of the future influence political subjects’ actions in the present and play a key role in composing the trajectory towards the future. I have critically applied this notion to the implementation of negative emission technologies in the climate-neutrality strategy. LÄS MER

  4. 3. A Petrographic and Paragenetic Characterization of the Ertelien Ni-Cu Deposit (Norway)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Alena Niarezka; [2023]
    Nyckelord :Ertelien Ni-Cu deposit; ore geology; enrichment processes; nickel; cobalt; copper; optical microscopy; electron probe micro-analysis; critical metals; Ertelien Ni-Cu fyndighet; malmgeologi; anrikningsprocesser; nickel; kobolt; koppar; optisk mikroskopi; elektronsondsmikroanalys; kritiska metaller;

    Sammanfattning : The escalating demand for metals driven by advancements in renewable energy technologies and hightech products has underscored the significance of understanding and characterizing ore deposits. This study focuses on the Ertelien Ni-Cu deposit in Norway, a region rich in nickel, cobalt, and copper resources—essential components for the transition to a sustainable energy future. LÄS MER

  5. 4. Distorted Imitations

    Master-uppsats, Konstfack/Inredningsarkitektur & Möbeldesign

    Författare :Irma Schlaucher Ståhl; [2023]
    Nyckelord :autencitet; rumslig installation; träådring; marmorering; sammanslagna mönster; imitation; hantverk; digitalisering; platsspecificitet; trender;

    Sammanfattning : An imitation of a material is usually associated with a lower value. It could partly be because materials linked to permanence and aging are often seen as something more exclusive. In materials such as stone and wood, we can often see a trace of time. It can be seen through the growth rings in diverse types of wood. LÄS MER

  7. 5. Magmatic processes and storage beneath Heard Island, southern Indian Ocean

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Liu Chun Wei; [2023]
    Nyckelord :Heard Island; Clinopyroxene; Thermobarometry; Magma storage depth;

    Sammanfattning : A young marine island called Heard Island is located in the southern Kerguelen Plateau in the Indian Ocean, a large igneous province created by the Kerguelen mantle plume. The two major geographic regions on Heard Island have two principal volcano-magmatic suites. LÄS MER
