A column of hot, partially molten material that rises from an intermediate depth in the mantle.

Rising jet of hot, partially molten material, thought to emanate from the deep mantle and responsible for intraplate volcanism.

whfreeman.com

A body of molten material (magma) that originates in the Earth's lower mantle, migrates upward through the mantle and crust, and emerges on the surface as a geographically stable centre of basaltic volcanic activity (a â€šhot spot') that can persist for millions of years (e.g. the hot spot beneath the Hawaiian Island chain).

els.net

A column of very hot rock rising up through the mantle.

wwnorton.com

A rising mass of hot mantle material that can create an area of volcanic activity in the center of a lithospheric plate.

geology.com

A buoyant mass of hot mantle material that rises to the base of the lithosphere. Mantle plumes commonly produce volcanic activity and structural deformation in the central part of lithospheric plates.

a giant pulse of heat that rises towards the surface from the core/mantle boundary

palaeo.gly.bris.ac.uk

a jet of molten lava from the Earth's mantle that reaches the Earth's surface, but is independent of the motion of the tectonic plates

a large upwelling of molten material from the earth's mantle. [AHDOS

memphisgeology.org

A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle. As the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts. It is a secondary way that Earth loses heat, much less important in this regard than is heat loss at plate margins (see Plate tectonics).
