  1. 1. Processes of Magma-crust Interaction Insights from Geochemistry and Experimental Petrology

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Frances M Deegan; Uppsala universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Canary Island magmatism; HP-HT experimental petrology; magma-crust interaction; Merapi volcano; radiogenic isotopes Sr; Nd; Pb ; stable isotopes O; B .; NATURAL SCIENCES Earth sciences Endogenous earth sciences Solid earth geology and petrology; NATURVETENSKAP Geovetenskap Endogen geovetenskap Berggrundsgeologi och petrologi; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : This work focuses on crustal interaction in magmatic systems, drawing on experimental petrology and elemental and isotope geochemistry. Various magma-chamber processes such as magma-mixing, fractional crystallisation and magma-crust interaction are explored throughout the papers comprising the thesis. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Khaled Hessami; Uppsala universitet.; [2002]
    Nyckelord :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;

    Sammanfattning : 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. Diagenesis and Sequence Stratigraphy an integrated approach to constrain evolution of reservoir quality in sandstones

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :João Marcelo Medina Ketzer; Uppsala universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics; Earth sciences; Geovetenskap;

    Sammanfattning : Diagenesis and sequence stratigraphy have been formally treated as two separate disciplines in sedimentary petrology. This thesis demonstrates that synergy between these two subjects can be used to constrain evolution of reservoir quality in sandstones. LÄS MER

  4. 4. Pan-African and Red Sea tectonics of eastern Eritrea

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Woldai Ghebreab; Uppsala universitet.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Pan-African tectonic grain; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : This thesis proposes that the Pan-African tectonic grain in eastem Eritrea influenced theCenozoic opening of the Red Sea. Evidence is based on studies of the structures and fabrics of various phases associated with both the Pan-African orogeny and subsequent Red Sea extension. LÄS MER

  5. 5. Deformation zones in models and nature

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Katarina Sofia Persson; Uppsala universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : Field studies encounter several complicating factors not studied in the models. Examples are oblique convergence, heterogeneous materials and thermal softening by intruding magmas. LÄS MER
