A mantle plume is a thermal diapir of hot rock that nucleates at the core-mantle boundary and rises through the Earth's mantle. Such plumes were invoked in 1971 to explain volcanic regions that were not thought to be explicable by the then-new theory of plate tectonics. Some of these volcanoes lie far from tectonic plate boundaries, e.g., Hawaii.

Apr 16, 2018 Mantle plumes may originate from the boundary between Earth's mantle and core, nearly 3000 km (about 1850 mi) beneath the surface. They are suspected in several places around the planet, like Hawaii, the Galapagos, and Iceland. For many years, evidence for a plume beneath Yellowstone has been difficult to identify.

Lower-bound estimates come from plume buoyancy flux calcula- tions [2,3], assuming that they represent the total heat flux from the core–mantle boundary (CMB). At the Earth’s surface, major intraplate volcanic hotspots, such as Hawaii, for example, are generally attributed to mantle plumes arising from the core–mantle boundary.

Define mantle plume and explain its role in plate tectonics.

Mantle plume is an upwelling of abnormally hot rock within the earth’s mantle which carries heat upward in narrow, rising columns, driven by heat exchange across the core-mantle boundary. Eventually, the rising column of hot rock reaches the base of the lithosphere, where it spreads out, forming a mushroom-shaped cap to the plume.

Mantle plume is thought to be hotter than the ambient asthenosphere. The melts generated from the hotter mantle may show higher MgO concentrations ( 12 wt.%). This is supported by the picritic basalt eruption for most of the plume-driven LIPS ( Jourdan et al., 2007 ).

May 30, 2002 1. Introduction. The plume model of Morgan to explain alignments of intra-plate volcanoes – known as hotspots – is widely accepted. Mantle plumes are then seen as objects largely independent of plates and large-scale mantle circulation and carrying heat and isotopes from their source (D″ or any internal boundary layer) to the surface (e.g. , ). ...

Oct 19, 2020 All known mantle plumes are characterized by a divergence between the location of the extreme heat flow and the recent volcanism center. To explain this phenomenon, it is proposed to consider the Coriolis effect influence, which deflects the magma flow within a mantle plume from the trajectory that is orthogonal to the planet surface.

With mantle candidate materials transmitting about 1000x more light in the visible than in the infrared for Fe/Mg near 0.1, and the flux from a hot body going roughly as T 4, radiative conduction is efficient in the mantle, and increasingly so with depth. Compression further enhances conduction (Eq. 4).
