  1. 1. 3D modelling and resistivity measurements for hydrogeological assessments in the northern part of Vombsänkan

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Farid Khorshidian; [2023]
    Nyckelord :Conceptual 3D modelling; Resistivity; Hydrogeology; Blue Transition; Vombsänkan; Vombverket; Earth and Environmental Sciences;

    Sammanfattning : The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. LÄS MER

  3. 2. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Henriette Nishimwe; [2023]
    Nyckelord :Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Sammanfattning : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. LÄS MER

  4. 3. Post-IR IRSL dating of K-feldspar from Loess at Lowland Point, SW England : Developing a Chronology for Past Climate Records

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elin Törnqvist; [2022]
    Nyckelord :loess; post-IR IRSL; Lowland Point; SW England; Quaternary; löss; post-IR IRSL; Lowland Point; England; kvartär;

    Sammanfattning : Loess deposits are terrestrial clastic sediments derived from aeolian deposition. Loess is transported in periglacial conditions and was mainly deposited in cold environments around glaciers during the Quaternary period. LÄS MER

  5. 4. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Matilda Persson; [2022]
    Nyckelord :loess; origin; La Motte; XRF; Quaternary; weathering; climate; lössjord; ursprung; La Motte; XRF; kvartär; vittring; klimat;

    Sammanfattning : With our changing climate it becomes more vital to understand the processes that control climate change in order to better understand possible future shifts. By doing this, predictions can be made about future climates and better prepare us for them. LÄS MER

  7. 5. Grain-Size Analysis of Loess Deposits of the Last Glacial Period, NW France

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Linnéa Rodin Borne; [2021]
    Nyckelord :loess; grain-size; glacial; Weichselian; Primel-Trégastel;

    Sammanfattning : Loess is an unique record of the paleoclimate of the Quaternary. Because it is directly deposited from the atmosphere, it can be used as a proxy for wind speed and circulation patterns. It can also be directly dated using luminescence. LÄS MER
