  1. 1. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Peter Dagbui; [2023]
    Nyckelord :Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Sammanfattning : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. LÄS MER

  3. 2. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Wanyi Li; [2022]
    Nyckelord :Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Sammanfattning : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. LÄS MER

  4. 3. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Dimitra Daniil; [2021]
    Nyckelord :magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

    Sammanfattning : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.
