1. 1. A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Tim Bjermo; [2022]
   Nyckelord :glacial geomorphology; remote sensing; LiDAR; sedimentology; glacitectonite; deformation structures; hummocky moraine; quaternary geology; deglaciation; glacial geomorfologi; fjärranalys; sedimentologi; glacitektonit; deformationstrukturer; småkullig morän; backlandskap; moränlandskap; kvartärgeologi; Earth and Environmental Sciences;

   Sammanfattning : Glacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with dead ice meltout and passive deglaciation.

3. 2. 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.

4. 3. Dynamics of a retreating ice sheet : a LiDAR study in Värmland, SW Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Alastair Goodship; [2017]
   Nyckelord :LiDAR; SIS; retreat; deglacial; DEM; geomorphology; Värmland; Earth and Environmental Sciences;

   Sammanfattning : Värmland in south central Sweden lies across the established zone of aquatic-terrestrial transition of the Scandinavian Ice Sheet margin during its rapid final retreat following the Younger Dryas. Recently acquired LiDAR data across Värmland allows more highly detailed observation and analysis of glacial landforms formed during this stage than has previously been possible. LÄS MER

5. 4. 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

7. 5. 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]
   Nyckelord :smältvatten; kullformad moränterräng; glaciär; diamikton; dödis; Törnåkra; melt water; hummocky moraine; glacier; diamict; dead ice; Earth and Environmental Sciences;

   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
