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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Frances M Deegan; Uppsala universitet.; [2010]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Early structural and metamorphic evolution of the Scandinavian Caledonides: a study of the eclogite-bearing Seve Nappe Complex at the Arctic Circle, Sweden

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lena Gunlög Albrecht; Lund University.; Lunds universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oblique compression.; C -type shear bands; anastomozing shear zones; tubular folds; lineation-parallel folds; northern Sweden; Grapesvare Nappe; Seve Nappe Complex; Finnmarkian; Eclogite; corona dolerite; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Abstract : In the Seve Nappe Complex of the Swedish Caledonides, coronitic diabases pass into eclogites; sometimes the transition occurs within one and the same boudin. Calculated pressure-temperature conditions for the eclogite facies stage are 20-27 kbar and 650-750°. READ MORE

  3. 3. Sveconorwegian orogenesis in the southwestern Baltic Shield - Zircon geochronology and tectonothermal setting of orthogneisses in SW Sweden

    University dissertation from Department of Geology, Lund University

    Author : Jenny Andersson; Lund University.; Lunds universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Petrology; Geologi; fysisk geografi; physical geography; Geology; structural markers; augen gneiss; orthogneiss; migmatite; ion microprobe; Pb-Pb evaporation; U-Pb; geochronology; zircon; Sweden; Mylonite Zone; Western Segment; Sveconorwegian orogen; Eastern Segment; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Abstract : The Mylonite zone (MZ) is a prominent late-Sveconorwegian lithological terrane boundary in the SW Baltic Shield along which large-scale crustal block movements took place during the Sveconorwegian orogeny. The southern section of the MZ also defines a conspicuous metamorphic break separating upper amphibolite and high-pressure granulite facies rocks in the parautochthonous Eastern Segment (ES), from middle amphibolite facies rocks in the overlying Western Segment (WS).

  4. 4. Tectonic implications of ca. 1.45 Ga granitoid magmatism at the southwestern margin of the East European Craton

    University dissertation from Audrius Cecys, Sölvegatan 12, 22362 Lund

    Author : Audrius Cecys; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geologi; southern Sweden; fysisk geografi; physical geography; Mesoproterozoic; geochemistry; syntectonic; petrology; structural geology; anisotropy of magnetic susceptibility; Danopolonian orogeny; Geology; granite;

    Abstract : Between ca 1.53 and 1.40 Ga, the southwestern margin of the East European Craton was subjected to extensive magmatism and deformation. While various suites of anorthositic, mangeritic and charnockitic-granitic rocks were emplaced between ca. READ MORE

  5. 5. Recovery from Acidification - Policy Oriented Dynamic Modeling

    University dissertation from Liisa Martinson, Department of Chemical Engineering, Lund, Sweden

    Author : Liisa Fransson; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Chemical technology and engineering; target loads; sea-salt episode; sulfate adsorption; SAFE; LRTAP; critical loads; integrated assessment;

    Abstract : Dynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. READ MORE
