1. 1. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

   Författare :Semere Solomon; KTH; []
   Nyckelord :Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

   Sammanfattning : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. LÄS MER

3. 2. Lithology of some Swedish eskers

   Författare :Marianne Lilliesköld; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Three esker systems passing different bedrock areas are lithologically investigated. Mostparts of the eskers are of subglacial, subaquatic type. The existence of a preglacial furrowof the River Dalälven is proposed to be the cause of the longtransported lithologiesfound in the Badelunda esker adjacent to the furrow. LÄS MER

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

   Författare :Gert Pettersson; Kvartärgeologi; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

   Författare :Joachim Albrecht; Kvartärgeologi; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Physical properties of coarse particles in till coupled to bedrock composition based on new 3D image analysis method

   Författare :Solomon Tafesse; Joanne Fernlund; Tore Påsse; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Three-dimensional shape; Grain size; Till lithology; Natural aggregate; Till provenance; Magnetic susceptibility of rock; Physical property of till; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Geoengineering; Geoteknik;

   Sammanfattning : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. LÄS MER
