  1. 6. Kinetic interpretation of microstructures in the Gällivare area; implications for deformation phases and related metamorphic events.

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Sammanfattning : 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. LÄS MER

  3. 7. Characterization of mineral parageneses and metamorphic textures in eclogite- to high-pressure granulite-facies marble at Allmenningen, Roan, western Norway

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Stylianos Karastergios; [2020]
    Nyckelord :Western Gneiss Region; Vestranden; Roan; Caledonides; marble; calc-silicate; metabasic; petrography; SEM-EDS; mineral chemistry; mineral equilibrium; P–T estimate; devolatilization; Earth and Environmental Sciences;

    Sammanfattning : The Roan peninsula in western Norway, Vestranden, is known for exposing one of the deepest parts of the Scandinavian Caledonian orogen, similar to the Western Gneiss Region. Throughout the Roan area, eclogites and high-pressure granulite- and amphibolite-facies gneisses occur, associated with supracrustal rocks including marbles, calc-silicate rocks and amphibolites.

  4. 8. Befintlig och framtida infrastruktur i Dennewitz malmkropp : Prognos och rekommendationer

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

    Författare :Johan Winsa; [2020]
    Nyckelord :bergmekanik; geologi; strukturgeologi; skadekartering; Dennewitz; Malmberget; LKAB;

    Sammanfattning : During mining in the Malmberget mine, large amounts of information such as damage mapping, geological mapping, seismic data and stress conditions are stored. All the data that is obtained is stored in several places with different methods, which makes it problematic to use. LÄS MER

  5. 9. Metamorphic paragenesis and P-T conditions in garnet amphibolite from the Median Segment of the Idefjorden Terrane, Lilla Edet

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anna Sartell; [2019]
    Nyckelord :P-T conditions; Sveconorwegian orogeny; Idefjorden Terrane; Median Segment; Göta Älv Shear Zone; garnet amphibolite; upper amphibolite facies; partial melting; Earth and Environmental Sciences;

    Sammanfattning : The Sveconorwegian orogeny (c. 1 Ga) lead to the recrystallization of large parts of southwestern Sweden, with widespread metamorphism as well as local migmatization. LÄS MER

  7. 10. Mineralogical and Geochemical characterization of the Fe-Cu-Occurrence and associated Hanging wall and Footwall Alteration halo of the Viscaria D-Zone, Kiruna District, Northern Sweden

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Madelen Estholm; [2019]
    Nyckelord :Alteration halo;

    Sammanfattning : Northern Norrbotten County is one of the three major ore producing districts in Sweden. Based on the predominance of epigenetic Cu-Au and Fe-oxide mineralization this region is regarded as a typical IOCG province. The massive to layered Viscaria Cu-deposit is proposed to be a VMS deposit of Besshi-type and is unique in deposit type of the region. LÄS MER
