  1. 1. Palaeosurfaces and palaeovalleys on North Atlantic previously glaciated passive margins reference forms for conclusions on uplift and erosion

    University dissertation from Stockholm : Institutionen för naturgeografi och kvartärgeologi

    Author : Johan M. Bonow; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palaeosurface; palaeovalley; uplift; valley; incision; glacial erosion; weathering; Neogene; southern Norway; West Greenland; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Abstract : Palaeosurfaces and palaeovalleys are landforms under destruction in the present climate and/or tectonic regime, and thus mainly reflect processes not active today. Uplifted palaeosurfaces exist along the formerly glaciated passive continental margins around the North Atlantic. READ MORE

  2. 2. Constraining the Uplift History of the Al Hajar Mountains, Oman

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Reuben Hansman; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oman; Al Hajar; mountain; uplift; orogeny; tectonics; structural; geology; Geology; geologi;

    Abstract : Mountain building is the result of large compressional forces in the Earth’s crust where two tectonic plates collide. This is why mountains only form at plate boundaries, of which the Al Hajar Mountains in Oman and the United Arab Emirates is thought to be an example of. READ MORE

  3. 3. Cryptic Orogeny uplift of the Al Hajar Mountains at an alleged passive margin

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Reuben Johannes Hansman; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; uplift; mountains; structural; low-temperature; thermochronology; dating; fission-track; U-Th He; U-Pb; calcite; structure-from-motion; photogrammetry; UAV; trishear; fault-propagation; Hafit; Al Hajar Mountains; United Arab Emirates; Oman; Geology; geologi;

    Abstract : Mountains evolve and grow because of the large forces that occur from the collision of tectonic plates. Plate boundaries change and move through time, and regions that were once stable, shallow-marine environments can be dragged into subduction zones and get transformed into vast mountain ranges.

  4. 4. Reliability-based evaluation of concrete dams

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Marie Westberg; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatial correlation; assessment; concrete dam; uplift; structural reliability analysis; existing structure;

    Abstract : Swedish concrete dams are designed and assessed based on deterministic design using safety factors. The combination of increasing age, new methods for calculation of design floods and increasing demands by society to ensure a high level of safety, has resulted in upgrading and rebuilding needs for dams.

  5. 5. 40Ar/39Ar, AFT and (U-Th)/He thermochronologic implications for the low-temperature geological evolution in SE Sweden

    University dissertation from Department of Geology, Lund University

    Author : Pia Söderlund; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 40Ar-39Ar; Fennoscandian Shield; U-Th He; AFT; geochronology; thermochronology; cooling; uplift;

    Abstract : The Oskarshamn and Forsmark areas in the Fennoscandian Shield, SE Sweden, have been chosen as potential sites for hosting highly radioactive nuclear waste. To evaluate their respective suitability, the geological history of the bedrock in these two areas has been investigated. This study has focused on the thermal evolution, from c. 500 °C to c.
