  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. First-arrival traveltime tomography of active-source data in the Kansanshi copper mine, northern Zambia

    Magister-uppsats, Uppsala universitet/Geofysik

    Författare :Vessela Hobson; [2019]
    Nyckelord :refraction seismics; tomographic inversion; Zambian Copperbelt; copper;

    Sammanfattning : Sedimentary rock-hosted deposits are a major source of copper and cobalt, with the Neoproterozoic central African Copperbelt being among the largest Cu-Co provinces in the world, accounting for around 15% of its copper resource. The deposits occur primarily in the carbonates and siliciclastic sediments overlying the basement, and formed during early diagenesis (around 820 Ma) and late diagenesis/metamorphism during the Pan-African Orogeny (580-520 Ma).

  4. 3. Modelling and interpretation of VTEM data from Soppero, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Linnéa Johansson; [2017]
    Nyckelord :Transient electromagnetic; geophysics; geophysical modelling; Soppero;

    Sammanfattning : The geological and geophysical knowledge about the northernmost part of Sweden has recently increased due to the Barents project, which includes acquisition of modern geophysical and geological information on behalf of the Swedish Geological Survey (SGU). During August 2013, a helicopter-borne versatile time domain electromagnetic (VTEM) survey was performed by Geotech Ltd, in the Soppero area northeast of Kiruna. LÄS MER

  5. 4. Structural analysis of the hinge region of the Islay Anticline.

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Elin Rydeblad; [2016]
    Nyckelord :Geology; structural geology; Islay; anticline; fluid flow;

    Sammanfattning : The hinge region of a major anticlinal fold structure in the SW Scottish Highlands was located in the eastern part of the Isle of Islay. The structure plunges gently NNW, with the hinge line measuring 02/026. LÄS MER

  7. 5. The Brennvinsfjorden Group of southern Botniahalvøya, Nordaustlandet, Svalbard : structure, stratigraphy and depositional environment

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Johan Nilsson; [1997]
    Nyckelord :The Brennvinsfjorden Group; the Goosbukta Anticline; the Gottwaldhøgda Fault; the Kapp Hansteen Group; Botniahalvøya; Nordaustlandet; Svalbard; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning: Den sedimentära enheten Brennevinsfjorden Group på Botniahalvøya, nordvästra Nordaustlandet, underlagrar diskordant en vulkanisk enhet av Grenvillisk ålder (Kapp Hansteen Group). De studier av Brennevinsfjorden Group som presenteras i detta arbete påvisar en ny stratigrafi och en bättre geografisk placering och tolkning av strukturen under basalkonglomeratet som utgör gränsen mellan Kapp Hansteen Group och Brennevinsfjorden Group.
