  1. 1. Stratigrafin i Hanöbukten under senaste glaciationen : en studie av borrkärnor från IODP’s expedition nr 347

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Gisela Åberg; [2014]
    Nyckelord :ice-rafted debris; lervarvskronologi; Bølling; IODP; Hanöbukten; Östersjön; Earth and Environmental Sciences;

    Sammanfattning : The development of Hanö Bay during the last ice age has been investigated by analyzing cores from IODP’s Balitc Sea Palaeoenvironment expedition in the Baltic Sea. By analyzing the presence of Ice Rafted Debris, correlating one of the varved clay units to Ringbergs (1991)regional varve chronology from southeastern Sweden, analyzing pollen grains and measuring loss on ignition a few gaps in the history of Hanö Bay has been uncovered.

  3. 2. A sedimentological and stratigraphical study of Veiki moraine in northernmost Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Þorbjörg Sigfúsdóttir; [2013]
    Nyckelord :Veiki moraine; glacial geology; Weichselian glaciation; northern Sweden; supraglacial lakes; Veikimorän; glacialgeologi; Weichselistiden; norra Sverige; supraglacial sjö; Earth and Environmental Sciences;

    Sammanfattning : Veiki moraine is a landform area consisting of rim-ridged subcircular hummocks and plateaus with depressions in between, mostly located within a N-S extending zone of a hummocky landscape. It is believed to have formed during the pre-late Weichselian and survived overriding by ice during the subsequent glaciations. LÄS MER

  4. 3. A sedimentological study on the formation of a hummocky moraine at Törnåkra in Småland, southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Gunnlaugur Brjánn Thorbergsson ; [2011]

    Sammanfattning : A detailed sedimentological study was made on a section along the side of a moraine hummock at Törnåkra in Småland, south Sweden. Two sedimentary units, A and B, were identified, based on their sediment characteristics. LÄS MER

  5. 4. Sedimentologiska och litostratigrafiska undersökningar i södra Malmös kvartära avlagringar, södra Sverige

    Magister-uppsats, Lunds universitet/Geologiska institutionen
