  2. 1. Major leaching processes of combustion residues : characterisation, modelling and experimental investigation

    Author : Jinying Yan; KTH; []
    Keywords : ;

    Abstract : Characterising leaching behaviour provides ample evidence toidentify the majorleaching processes of combustion residues.Neutralisation and chemical weatheringgovern the leachingreactions and control the release of major, minor and traceelementsfrom combustion residues, and are thus considered to bethe major leaching processes.

  4. 2. Organic geochemical investigation of sources, transport and fate of terrestrial organic matter in the southeast Laptev Sea

    Author : Emma Karlsson; Örjan Gustafsson; Volker Brüchert; Sebastian Sobek; Rienk Smittenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi; Marine Geoscience; marin geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Permafrost carbon stores have been suggested to react to warming trends with increased terrestrial loading to its coastal waters. Presently, the warming has been seen to be especially high in the East Siberian Arctic and the fate of the major release of terrestrial matter to these coasts is yet to be detailed. READ MORE

  5. 3. Geochemical modelling of acid mine drainage in mill tailings : Quantification of kinetic processes from laboratory to field scale

    Author : Sally Ursula Salmon; KTH; []
    Keywords : geochemistry; biogeochemistry;

    Abstract : Assessment of the potentially acidic, heavy metal-ladenleachates that leave deposits of sulfide ore mill tailings andevaluation of various possible options for mill tailingremediation are scientific problems of increasing practicalimportance. High costs may be associated with the mill tailingremediation, not least after recent changes in Swedish andEuropean environmental legislation. READ MORE

  6. 4. How do metamorphic fluids move through rocks? : An investigation of timescales, infiltration mechanisms and mineralogical controls

    Author : Barbara I. Kleine; Alasdair D. L. Skelton; John C. Schumacher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metamorphic fluid flow; fluid-rock interaction; fluid infiltration mechanisms; fluid flux rates; thermodynamic modeling; reaction front propagation; fluid flux calculation; Geology; geologi;

    Abstract : This thesis aims to provide a better understanding of the role of mountain building in the carbon cycle. The amount of CO2 released into the atmosphere due to metamorphic processes is largely unknown. READ MORE

  7. 5. Geochemical Development of Proterozoic Granites in the SW Baltic Shield

    Author : Kirsten Holme; Berggrundsgeologi; []
    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.
