  1. 1. Eurasian Arctic Tectonics: Geology of Severnaya Zemlya (North Kara Terrane) and Relationships to the Timanide Margin of Baltica

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henning Lorenz; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Arctic; Severnaya Zemlya; North Kara Terrane; Baltica; bedrock; geology; tectonics; Timanides; Caledonides; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Abstract : The North Kara Terrane (NKT), with Severnaya Zemlya as its main outcrop area, constitutes the Palaeozoic and older rocks of the northern part of the Kara Shelf. Potential field data suggest a continuation into the eastern Barents Shelf. READ MORE

  2. 2. Tectonic History and Present-Day Deformation in the Zagros Fold-Thrust Belt

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Khaled Hessami; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Zagros; Orogeny; Unconformities; Iran; Growth folds; Middel East; Tectonics; Models; GPS; basement; Seismicity; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : This thesis uses various approaches such as observation of satellite images, field investigations, analogue modeling and GPS measurements to constrain deformation of the basement and sedimentary cover of the Zagros fold-thrust belt in time and space.Focal mechanism solutions of most earthquakes indicate that deformation in the Zagros basement is due to shortening and thickening through numerous thrust faults.

  3. 3. Holocene environmental changes and climate variability in the Eastern Mediterranean Multiproxy sediment records from the Peloponnese peninsula, SW Greece

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Christos Katrantsiotis; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mediterranean; Greece; Peloponnese; Holocene; sediments; diatoms; n-alkanes; stable isotopes; tectonics; climate variability; monsoons; NAO; NCP; naturgeografi; Physical Geography;

    Abstract : This thesis presents multiproxy reconstructions of the mid to late Holocene climate and environmental changes in the Peloponnese peninsula, SW Greece. The combined dataset consists of diatom, biomarker and X-ray fluorescence spectrometry (XRF) elemental data in radiocarbon-dated sediment cores taken from the Agios Floros fen and the Gialova Lagoon in SW Peloponnese and the Ancient Lake Lerna in NE Peloponnese.

  4. 4. Tectonics of the middle Ural

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Friberg; Uppsala universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : This thesis concerns the crustal structure and tectonic evolution of the Middle Urals. Theresults are based on near-vertical reflection seismic profiling, geological fieldobservations and single zircon geochronology,The Ural Mountains delimit. the eastern margin of Baltica. Prior to PalaeozoicUralian orogeny, this margin was bounded by an ocean. READ MORE

  5. 5. 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
