  1. 11. Single-Grain Zircon U-Pb Dating and Magnetic Susceptibility of Polish Loess to Determine Late Quaternary Dust Provenance and Paleoclimate

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexandra Engström Johansson; [2018]
    Keywords : dust provenance; Polish loess; paleoclimate; single-grain zircon U-Pb dating; magnetic susceptibility; härkomstområden för atmosfäriskt stoft; polsk lössjord; paleoklimat; U-Pb datering av zirkoner; magnetisk susceptibilitet;

    Abstract : Windblown mineral dust has accumulated into thick loess layers across the European continent. Loess deposits are valuable paleoclimatic archives as they record climate change on centennial- to glacialinterglacial timescales. READ MORE

  3. 12. The Formation of Granite Magma Chambers in the Mourne Mountains, Northern Ireland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Björkgren; [2017]
    Keywords : granite; magma chamber; Mourne Mountains; space problem; AMS; granit; magmakammare; Mournebergen; space problem; AMS;

    Abstract : The Mourne Mountains situated in County Down, Northern Ireland, mainly consists of solidified granite magma chambers that intruded ~ 56 million years ago into the surrounding greywacke. How granite magma chambers are emplaced in the crust has for years been a debate amongst scientist of volcanology, and is referred to as the ‘space problem’ debate. READ MORE

  4. 13. MRI-based quantification of magnetic susceptibility: Assessment of measurement and calculation accuracy

    University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Author : Emma Olsson; [2016]
    Keywords : Medicine and Health Sciences;

    Abstract : An object in an external magnetic field will be magnetized and the degree of magnetization is dependent of the magnetic susceptibility of the object. The local magnetic field inside and around an object in the MR scanner will change due to the magnetization of the object. READ MORE

  5. 14. A palaeoenvironmental study of a peat sequence from Iles Kerguelen (49°S, Indian Ocean) for the Last Deglaciation based on pollen analysis

    University essay from Lunds universitet/Geologiska institutionen

    Author : Victor Henao; [2015]
    Keywords : Earth and Environmental Sciences;

    Abstract : In recent years, the Southern Hemisphere (SH) and the vast Southern Ocean (SO) have gained awareness and importance within the scientific community in relation to global climate change and the global CO2 cycle, par-ticularly since the Last Glacial Maximum (LGM) and into the Holocene. It is believed that the Southern Hemi-sphere Westerlies (SHW) play a key role in regulating climate change in the mid-to-high latitudes of the SH, thus reconstructing the SHW latitudinal positioning since the LGM has been crucial.

  6. 15. Submarine slope instability as a cause of contaminated sediment dispersal in Ångermanälven, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hannes Berg Wiklund; [2015]
    Keywords : Submarine landslides; contaminated sediments; weak layers; Ångermanälven; Undervattenskred; förorenade sediment; svaga lager; Ångermanälven;

    Abstract : This study aims at providing results for the analysis of the stratigraphy underlying contaminated sediments in Ångermanälven. The contaminated sediments, containing heavy metals and persistent organic pollutants, are derived from wastewater discharged into Ångermanälven from nearby paper and pulp industries. READ MORE
