  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.

  5. 4. A sedimentological and stratigraphical study of Weichselian sediments in the Tvärkroken gravel pit, Idre, west-central Sweden

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Johanna Anjar; [2008]
    Nyckelord :Dalarna; interstadial; glaciolacustrine; braided river; till; glacilakustrin; flätflod; morän; Earth and Environmental Sciences;

    Sammanfattning : A detailed sedimentological study was made on six section walls in the Tvärkroken gravel pit, Idre, west-central Sweden. Based on sediment characteristics, three sedimentary units, units 1-3, were identified. The lowest unit, unit 1, was formed by deposition from sediment-loaded underflows into a stagnant basin.

  7. 5. An architectural element analysis of a large-scale thrust complex, Kanin Peninsula, NW Russia : interaction between the Barents and Kara Sea ice sheets

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Lena Håkansson; [2003]
    Nyckelord :glaciotectonism; architectural element analyses; large-scale thrust complexes; basal tills; NW Russia; Earth and Environmental Sciences;

    Sammanfattning : Den Eurasiska shelfen var under Weichsel istiden täckt av inlandsisar centrerade i Barents och Kara Havet. Kanin Halvön i nordvästra Ryssland upptar en nyckelposition för att registrera de shelfbaserade isarnas passage över till fastlandet. LÄS MER
