2. 1. Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden

   Author : Mattias Lindén; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Sedimentology; Geologi; physical geography; Geology; glaciotectonic; thrust stacking; deforming bed; ribbed moraine; Niemisel moraine; De Geer moraine; isostatic uplift; glaciodynamics; deglaciation; klimatologi; kartografi; marklära; Fysisk geografi; geomorfologi; geomorphology; cartography; climatology; pedology;

   Abstract : The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.

4. 2. Marginal behaviour of the last Scandinavian Ice Sheet during its final termination and deglaciation over Northeastern Germany

   Author : Joachim Albrecht; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; Marginal dome; Deglaciation; Clast lithology; Clast fabric; Germany; Pomeranian; Weichselian; Lithostratigraphy; marklära; kartografi; klimatologi; Sedimentology; Sedimentologi;

   Abstract : This thesis presents results from studies on geomorphology, lithostratigraphy and ice flow patterns during the final termination and deglaciation of the last Scandinavian Ice Sheet in NE Germany. Ice flow patterns derived from till fabrics and glaciotectonical data indicate that short-lived marginal domes had formed during the advance and the retreat of the last Scandinavian Ice Sheet in NE Germany.

5. 3. Late Quaternary ice sheet history and dynamics in central and southern Scandinavia

   Author : Timothy Johnsen; Helena Alexanderson; James T. Teller; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scandinavian ice sheet; ice sheet dynamics; luminescence dating; cosmogenic exposure dating; geochronology; moraine; interstadial; deglaciation; nunatak; Quaternary geology; Kvartärgeologi; kvartärgeologi; Quarternary Geology;

   Abstract : Recent work suggests an emerging new paradigm for the Scandinavian ice sheet (SIS); one of a dynamically fluctuating ice sheet. This doctoral research project explicitly examines the history and dynamics of the SIS at four sites within Sweden and Norway, and provides results covering different time periods of glacial history.

6. 4. Weichselian glaciations in the middle Notec River region, northwest Poland

   Author : Gert Pettersson; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quaternary Geology; Kvartärgeologi; Geology; Geologi; Vistulian; Weichselian; Lithostratigraphy; Poland; Chodziez; Clast lithology; Clast fabrics; Deglaciation; Ice stream; Sedimentology; Sedimentologi; geomorphology; klimatologi; geomorfologi; climatology;

   Abstract : This thesis presents results of studies on the ice flow pattern and ice movement mechanism during the Weichselian glaciations in the middle Notec River area, NW Poland. A new lithostratigraphy of the study area has been established, based on correlation of stratigraphical position, clast lithology, fabrics and grain size composition of till units. READ MORE

7. 5. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

   Author : Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

   Abstract : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. READ MORE
