Research Spotlight: Ridge versus plume: A closer look at the seafloor south of Iceland

Site of many volcanoes, Iceland is generally thought to be fueled by a plume of hot mantle rising from the core-mantle boundary. It also sits atop the Mid- Atlantic Ridge, the plate boundary where the North American plate is spreading away from the Eurasian plate. Because of the possible interaction of these complex deep and shallow geodynamic processes, the degree to which ridge processes may influence plume processes and vice versa is a subject of much debate.
