    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 ...

    Magmatic olivine as a tool to investigate geochemical mantle heterogeneities beneath Iceland 
    Rasmussen, Maja Bar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2021-01)
    The extent of compositional and lithological heterogeneity in Earth’s convecting mantle, caused by the recycling of oceanic and continental lithosphere, has long been a subject of interest to geochemists and geophysicists. A fundamental outstanding ...
