  1. 1. A pre-LGM sandur deposit at Fiskarheden, NW Dalarna : sedimentology and glaciotectonic deformation

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anne-Cécile Flindt; [2016]
    Nyckelord :deformation; structures; sandur; glaciotectonic; glaciofluvial; fault-propagation fold; Earth and Environmental Sciences;

    Sammanfattning : The Fiskarheden quarry, situated in NW Dalarna, central Sweden, reveal thick deposits of coarse-grained sediments of Scott type facies association; a sandur deposited in an ice-proximal proglacial environment. Preliminary OSL dating of the sandur sediments suggest that they are of a pre-Saalian age (>200 000 years). LÄS MER

  3. 2. Jökulhlaups: their associated landforms and landscape impacts

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Martin Bernhardson; [2011]
    Nyckelord :physical geography; geomorphology; Jökulhlaup; Sandur; Skeiðarársandur; naturgeografi; geomorfologi; Earth and Environmental Sciences;

    Sammanfattning : Glacial outburst floods also known as jökulhlaups are important features connected with glaciers globally. They may induce catastrophic floods as well as new landforms. LÄS MER

  4. 3. Förutsättningar för jökellopp vid Fox Glacier, Nya Zeeland

    Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Moa Hamré; [2011]
    Nyckelord :jökulhlaup; Fox Glacier; Franz Josef Glacier; glacier outburst floods;

    Sammanfattning : A great number of tourists visits each day the Fox Glacier in New Zealand and are subjected todangers such as jökulhlaups. This phenomena can occur suddenly and in a destructive way when abuilt up of water suddenly bursts and releases large amounts of water. LÄS MER

  5. 4. Lycksabäcken, ett riksintresse med komplext deglaciationsförlopp : Presentation av ett möjligt scenario över deglaciationen i området

    Kandidat-uppsats, Institutionen för ekologi, miljö och geovetenskap

    Författare :Tove Hägglund; [2011]
    Nyckelord :Deglaciation; glacifluvala landformer; sandur; Lycksabäcken; Norra Sverige;

    Sammanfattning : The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservation because of its geological values with many unique landforms. Many of these landforms indicate that the deglaciation process in the area was very complex. However, the deglaciation process in the area has not previously been fully understood. LÄS MER

  7. 5. En glacialgeologisk studie av morän och moränfyllda sprickor i underliggande sandursediment, Örsjö, Skåne

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Gunnar Carlemalm; [1999]
    Nyckelord :geografi; geologi; glacialgeologi; morän; sandursediment; Örsjö; Skåne; Earth and Environmental Sciences;

    Sammanfattning : The late quaternary deposits at Örsjö, 2 km east of the village Skurup, south Skåne consist of three main units. Direct above the bedrock there is a diamicton correlated to Allarp till according to Lagerlund (1980). The seeond unit, the so called Örsjöbeds, consist of up to 40 meter sorted sediments in general coarsening upwards. LÄS MER
