Is intra-plate volcanism dominated by deep or shallow processes?
Abstract
Intra-plate ‘hotspots’ have for a long time been attributed to cylindrical plumes made of hot, buoyant mantle that rises from great depths as deep as the core-mantle boundary. However, there have been a lot of speculations and controversies surrounding the arguments on the true source of these volcanic ‘hot spots’ with numerous scientists siding to defend the shallow volcanicity process as a more tangible explanation. Theories and models of deep volcanicity processes nevertheless dominate the scientific field as the mantle plume-derived sources for hotspot tracks that occur along the oceanic lithosphere are a more straightforward standpoint of mantle
