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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  3. 2. The Magnetic Properties and Fabrics of Upper Pleistocene Loess on La Motte, Jersey, and their Palaeoclimate Implications

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anya Hawkins; [2022]
    Keywords : last glacial; magnetic susceptibility; AMS; temperature dependent magnetic susceptibility; palaeowind reconstruction;

    Abstract : The island of Jersey is an interesting location for palaeoclimate reconstruction given the likely impact of variations in North Atlantic climate and European ice sheet extent during the last glacial period considering their proximal location. These last glacial climatic variations are recorded in the loess sequence from La Motte, Jersey and in order to reconstruct these changes, a detailed magnetic analysis was performed. READ MORE

  5. 4. Palaeomagnetism and Magnetic Fabrics of The Lake Natron Escarpment Volcano-sedimentary Sequence, Northern Tanzania

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gülsinem Polat Wiers; [2019]
    Keywords : Natron Escarpment; Northern Tanzania; Paleomagnetism; Geomagnetic Polarity Time Scale; Anisotropy of Magnetic Susceptibility;

    Abstract : The East African Rift System diverges in the Lake Natron Basin of Northern Tanzania and is a major zone of continental extension and crustal thinning with resulting in active tectonics and volcanism. The discovery of Acheulean technology in Olduvai Gorge and Peninj as well as the presence of significant volcanic centers, has made in the region subject to studies in various disciplines. READ MORE

  6. 5. Characterizing magnetic susceptibility and remanent magnetization of magnetite and hematite rich drill-core samples at Blötberget

    University essay from Uppsala universitet/Geofysik

    Author : Andreas Bjork; [2018]
    Keywords : Verwey; Morin; Curie; Néel; magnetite; hematite; alteration; iron-ore; quality control; kappabridge; hysteresis; susceptibility; anisotropy; Verwey; Morin; Curie; Néel; magnetit; hematit; oxidation; järnmalm; kvalitetskontroll; kappabridge; hysteresis; susceptibilitet; anisotropi;

    Abstract : Laboratory magnetic measurements are used to develop a methodology to characterize the Kiruna-type Rare Earth Elements (REE) bearing apatite iron-oxide deposits at Blötberget in central Sweden. This high-grade ore deposit is known to have sharp boundaries between lens shaped main ore bodies of magnetite-rich ore, and a complex hematite-rich ore associated with pegmatites and skarn formation.
