  1. 1. Fluid-rock interaction in two seismically active areas : The Tjörnes Fracture Zone, northern Iceland and the Shillong Plateau, northeastern India

    Författare :Lillemor Claesson; Alasdair Skelton; Steven Ingebritsen; Stockholms universitet; []
    Nyckelord :Tjörnes Fracture Zone; Shillong Plateau; Iceland; India; hydrogeochemical monitoring; earthquakes; geothermal; transition metals; dissolution; basalt; feldspar weathering; source switching; Geology; geologi;

    Sammanfattning : Hydrogeochemical monitoring can improve our understanding of fluid-rock interaction, and may detect anomalies that are precursory to- or caused by- earthquakes. In this study, hydrogeochemical monitoring was carried out in two distinct tectonic settings, to study coupling between hydrogeochemical changes and seismic activity. LÄS MER

  4. 3. How do fluids move through rocks? : High fluxes of CO2 in the Earth's crust

    Författare :Barbara Kleine; Alasdair Skelton; Iain Pitcairn; Sandra Piazolo; Jaroslaw Majka; Zhihong Zhao; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metamorphic fluid flow; blueschist preservation; fluid-rock interaction; Geology; geologi;

    Sammanfattning : Metamorphic hydrous, CO2-bearing fluids play a critical role in the global carbon cycle. However, how big this influence is on the global carbon cycle and therefore on global climatic processes, is unknown. The actual amount of CO2 which is released into the atmosphere due to metamorphic processes is still debated. LÄS MER

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

    Författare :Barbara I. Kleine; Alasdair D. L. Skelton; John C. Schumacher; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Fluid-induced alteration of metasedimentary rocks in the Scottish Highlands

    Författare :Alexander Lewerentz; Alasdair Skelton; Patrick Crill; Charlotte Möller; Jay Ague; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metamorphic fluids; metamorphic fluid flow; fluid-rock interaction; metamorphic fluid fluxes; Geology; geologi;

    Sammanfattning : Fluids, mainly H2O and CO2, are released from H- and C-bearing phases during prograde metamorphism. Because of the buoyancy of these fluids, they rise within the crust towards the surface of the Earth. Metamorphic fluids take advantage of permeable horizons, shear zones, fold hinges, fractures, and are channelled into high-flux zones. LÄS MER
