The deep Earth origin of the Iceland plume and its effects on regional surface uplift and subsidence

Abstract The present-day seismic structure of the mantle under the North Atlantic Ocean indicates that the Iceland hotspot represents the surface expression of a deep mantle plume, which is thought to have erupted in the North Atlantic domain during the Palaeocene. The spatial and temporal evolution of the plume since its eruption is still highly … Read more…

Dynamic topography of passive continental margins and their hinterlands since the Cretaceous

Even though it is well accepted that the Earth’s surface topography has been affected by mantle-convection induced dynamic topography, its magnitude and time-dependence remain controversial.  The dynamic influence to topographic change along continental margins is particularly difficult to unravel, because their stratigraphic record is dominated by tectonic subsidence caused by rifting. We follow a three-fold … Read more…
