  1. 1. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ellen Svens; [2024]
    Nyckelord :Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

    Sammanfattning : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

  3. 2. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Morgan Eliasson; [2023]
    Nyckelord :Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

    Sammanfattning : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. LÄS MER

  4. 3. Estimating CO2 emissions with satellite and traffic data: a Swedish practical case study

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Margaux Boucher; [2022]
    Nyckelord :CO2 emissions monitoring; European Union industry monitoring; Swedish industry monitoring; Satellite imagery; Carbon footprint; space monitoring.;

    Sammanfattning : The large carbon footprint of industries is one of the main issues raised when talking about climate change. Active carbon monitoring methods need to be implemented to give transparency to the industry market and to spread awareness and information. LÄS MER

  5. 4. Climate Neutral Roadmap in Fossil Free Competitiveness for Paroc, Sweden : what Paroc can do to meet up with the roadmap from Fossil Free Sweden

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Felix Mörk; [2021]
    Nyckelord :Climate neutral; Fossil free; Mineral wool; Competitiveness; Intercommunion; Plasma burner; Oxy fuel; Hydrogen gas.;

    Sammanfattning : Today’s society is standing in front of a revolution where fossil energy should be replaced with renewable energy. Governmental agencies and policy makers have formed goals and regulations to become greener, and the organisation Fossil Free Sweden has published roadmaps for fossil free competitiveness. LÄS MER

  7. 5. Evaluation of tomographic methods for limestone characterization : Using synchrotron-based X-ray tomography to determine porosity, internal structure and internal distributions in limestone

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Albert Askengren; [2021]
    Nyckelord :Limestone; X-ray tomography; Synchrotron; XRT; Synchrotron-based XRT;

    Sammanfattning : Limestone is a raw material in the cement and quicklime industry and knowledge about limestone characteristics can help improve and optimize production processes. In the end this can lead to a reduction in CO2 emissions from the industry. In this project X-ray tomography (XRT) was used to examine limestone samples. LÄS MER
