    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 ...
