    Exploration of the Microbial Communities within the Basaltic Subsurface of the Volcanic Island Surtsey in Iceland 
    Bergsten, Pauline (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-09)
    Surtsey is a volcanic island located on the south-east offshore extension of the Icelandic rift zone. It was formed during successive eruptions from the seafloor in 1963-1967 and has been officially protected and studied ever since. It represents ...

    Explosive activity in flood lava eruptions: a case study of the 10th century Eldgjá eruption, Iceland 
    Moreland, William (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-07-14)
    The 10th century Eldgjá flood lava eruption, southern Iceland, was the most voluminous eruption on Earth in the last 1100 years, erupting up to 21.0 km3 of transitional alkali basaltic magma of rather uniform composition. While 19.7 km3 was erupted as ...

    From partial melting to lava emplacement: the petrogenesis of some Icelandic basalts 
    Nikkola, Paavo (Faculty of Science, University of Helsinki; Faculty of Earth Sciences, University of Iceland, 2020-03-20)
    This thesis provides insights into the petrogenesis of Iceland basalts via three subprojects. The first uses olivine macrocrysts as a proxy for mantle melting conditions below Iceland, the second utilizes petrological thermobarometry to resolve the ...

    Mineral storage of carbon in basaltic rocks 
    Snæbjörnsdóttir, Sandra Ósk (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-04-19)
    In-situ carbonation of basaltic rocks could provide a carbon storage solution for the long term. Permanence is essential for the success and public acceptance of carbon storage. The aim of this study was twofold, to evaluate and make a first estimate ...

    Surtsey: Basalt alteration by seawater in a low-temperature geothermal system 
    Prause, Simon (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2023-03)
    The chemical interaction between seawater and basalt at low temperatures (≤150°C) ranks among the more significant factors controlling the composition of seawater and the oceanic crust. However, the time-integrated geochemical and petrographic outcomes ...
