  1. 1. Geochemical Development of Proterozoic Granites in the SW Baltic Shield

    University dissertation from SMC, Box 839, SE-981 28 Kiruna, Sweden

    Author : Kirsten Holme; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; principal component analysis; granite classification; magma evolution; magma genesis; granite; Eastern Segment; Western Segment; Southwestern Swedish Gneiss Complex; Sweden; Sveconorwegian Orogen; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : The plutonic rocks in the Western Segment of the Southwestern Swedish Gneiss Complex show a distinct geochemical evolution. The 1.6 Ga Åmål granitoids and Slottsbron migmatites are a quartz dioritic to granodioritic, calc-alkaline rock suite with smooth, but somewhat fractionated, REE and other trace-element patterns.

  2. 2. Specific surface area of some minerals commonly found in granite

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Isabelle E. Dubois; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Granite; Mineral; Surface area; BET; Sorption; Particle size;

    Abstract : The specific surface area, determined by the BET method, is a parameter often used to scale results of mineral studies of surface reactions in terms of rate and capacity to the field scale. Such extrapolations of results from small-scale laboratory experiments to the field-scale are important within many environmental applications. READ MORE

  3. 3. The dynamic emplacement of felsic magma in the upper crust

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tobias Mattsson; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laccolith; cryptodome; magma emplacement; magma flow; magma rheology; granite; rhyolite; pluton; AMS; XCT; thermobarometry; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : Felsic magma intrudes earth’s upper crust through a variety of mechanisms. Magma intrusion growth and shape have mainly been explained in terms of host rock properties and intrusion depth, while considering the magma as an overpressurised fluid. READ MORE

  4. 4. Fluoride in surface water and groundwater in southeast Sweden sources, controls and risk aspects

    University dissertation from Växjö : Linnaeus University Press

    Author : Tobias Berger; Linnéuniversitetet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorine; fluoride; water-rock interaction; granite; crystalline bedrock; surface water; groundwater; Götemar; drinking water quality; aluminium; speciation; fluorosis; PBA; Miljövetenskap; Environmental Science;

    Abstract : The aim of this thesis is to determine the sources, controls and risk aspects of fluoride in surface water and groundwater in a region of southeastern Sweden where the fluorine-rich 1.45 Ga circular Götemar granite (5 km in diameter) crops out in the surrounding 1.8 Ga granites and quartz monzodiorites (TIB rocks).

  5. 5. Time dependent material properties of shotcrete for hard rock tunnelling

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lars Elof Bryne; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; rock; granite; bond strength; compressive strength; pullout testing; failure modes; interfacial transition zone; micro structure; ettringite; set accelerator; shrinkage; drains; glass fibres; laboratory testing; tunnels tunnelling;

    Abstract : In this thesis different mechanical properties for shotcrete (sprayed concrete) such as compression strength, bond strength, bending tensile strength, elastic modulus, free and restrained shrinkage as a function of its age was investigated. One of the main issues was to investigate the difference between ordinary cast concrete and shotcrete. READ MORE
