  1. 1. The Effect of Mechanical Characteristics of Basal Decollement and Basement Structures on Deformation of the Zagros Basin

    University dissertation from Uppsala University Library

    Author : Abbas Bahroudi; John Cosgrove; [2003]
    Keywords : decollement; extension; Zagros; Hormuz salt; shortening; basement faults; Arabia; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Two fundamental structural elements, basement architecture and basal decollement, play a significant role in the evolution of a tectonically active region. Using different approaches (field data, literature review and analogue models) this thesis demonstrates that these two elements affected the deformation style in the Zagros fold-thrust belt during Mesozoic extensional and Cenozoic contractional episodes.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Khaled Hessami; James Jackson; [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. Three-dimensional analysis of aeromagnetic and gravimetric data of sedimentary basins from Panama, Central America

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Luis E. Santamaria Vallejos; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Abstract : The knowledge of the geology of the sedimentary basins from the Gulf of Panama is still quite limited. There is a lack of data from the basin geometry, the thickness, the continuity and connection between the basins, and from the characteristics of the crystalline basement rocks beneath the sedimentary basins.

  4. 4. Environmental and hydrogeological geophysics with applications in Thailand, Laos, and Sweden

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kamhaeng Wattanasen; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Abstract : This thesis presents applications of geophysical methods in the fields of environment and hydrogeology. In relation to environmental problems, two different geophysical surveys have been carried out; one to study an arsenic contaminated area in the southern Thailand (paper I) and a second to locate shallow faults in Quaternary sediments in an area around the Ongkharak Nuclear Research Centre, central Thailand (paper II).

  5. 5. Geophysical studies in the western part of the Siljan Ring Impact Crater

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Harbe Muhamad; Christopher Juhlin; Alireza Malehmir; Daniel Sopher; Lars Nilsen; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Siljan ring impact structure; Seismic reflection; Down-hole logging; Gravity; Magnetic; Tomography; Paleozoic rocks;

    Abstract : This thesis utilizes several geophysical methods to study the Siljan Ring impact structure, focusing on the western part of the structure. This thesis, and the three papers upon which it is based, reports on attempts to delineate the Paleozoic rocks at depth within the annular ring graben and characterize their structure. READ MORE
