  1. 1. Determination of depositional environment and luminescence dating of Pleistocene deposits in the Biely Váh valley, southern foothills of the Tatra Mountains, Slovakia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ingrid Bejarano Arias; [2020]
    Nyckelord :Luminescence dating; glacifluvial deposits; sedimentological analysis; High Tatra Mountains; IRSL dating.; Earth and Environmental Sciences;

    Sammanfattning : The Tatra Mountains have had several glaciations during the Quaternary. The deposits located in the southern foothills were classified as glacifluvial, based on geomorphology, but its sediments have not been studied in detail. LÄS MER

  3. 2. Combining luminescence dating and sedimentary analysis to derive the landscape dynamics of the Velická Valley in the High Tatra Mountains, Slovakia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Roos van Wees; [2020]
    Nyckelord :IRSL; Chronology; Sedimentology; Landscape development; Middle Pleistocene; Modern Analogues; Clast shape analysis; Maximum particle size; High Tatras; Slovakia; Earth and Environmental Sciences;

    Sammanfattning : Luminescence dating is widely used in combination with sedimentological analysis to reconstruct the landscape development of the Quaternary period. Here, quartz and K-feldspar measurements are used to date and evaluate the luminescence characteristics of sediments from seven sites of the lower part of the Velická valley (995-1250 m a.s.l.

  4. 3. Processes of lateral moraine formation at a debris-covered glacier, Suldenferner (Vedretta di Solda), Italy

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Monika Rabanser; [2019]
    Nyckelord :Lateral moraines; Moraine genesis; Moraine stability; Debris-covered glaciers; Clast shape; Alps; Sedimentology; Glacier fluctuations; Earth and Environmental Sciences;

    Sammanfattning : Lateral moraines are key features of glacial landscapes in high-alpine mountain areas. Research on lateral moraine formation is mostly limited to clean-ice glaciers; lateral moraine formation at the margins of debris-covered glaciers is currently poorly understood in an Alpine and sedimentological context.

  5. 4. Different generation of controlled moraines in the glacier foreland of Midtdalsbreen, Norway

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Xavier Allègre; [2018]
    Nyckelord :Glacial sedimentology; glaciology; geomorphology; palaeoenvironmental reconstruction;

    Sammanfattning : A series of small mounds (< 3m) were sampled in the foreland of Midtdalsbreen outlet glacier, southern Norway. These landforms were interesting, especially at site number 1 because they were located very close to a higher Little Ice Age (LIA) moraine (> 5 m), thereby informing the dynamic of the glacier after the LIA at this location.

  7. 5. Sedimentationsprocesser och avlagringsmiljö för en kantrygg kring platåleran vid Rydsgårds gods i backlandskapet söder om Romeleåsen, Skåne

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Sven Birger Sundberg; [2000]
    Nyckelord :Quaternary; ice-walled lake plain; rim-ridge; debris flow; turbidite; subaquatic; supraglacial; hummocky; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning: Platåleror utgör ett markant inslag i det inre backlandskapet söder om Romeleåsen i Skåne. De är kvadratkilometer stora, cirkulära lerområden, med en svagt undulerande yta som täcker landskapets högsta kullformer. LÄS MER
