English term or phrase: mantle plume
Definition from Digital Atlas of Idaho:
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.

Example sentence(s):
  • Scientists believe mantle plumes can last hundreds of millions of years, and that their heat can create phenomena such as Yellowstone National Park or the string of Hawaiian Islands. Science Centric
  • Above a certain depth, the head of the plume begins to melt and spread out under the crust, until it finds a crack and pours through. The theory of mantle plumes predicts an initial flood of lava lasting tens of millions of years, which means that each hot spot should have an associated flood basalt. University of California
  • The first few million years of a newly arrived mantle plume seem to be the most fertile in terms of magma production and flood basalts are therefore formed in a very short period of geological time. The Geological Society

pluma del manto, penacho
Definition:
Fenómeno consistente en el ascenso de una estrecha columna de materiales del manto calentados, desde la base del manto terrestre hasta la base de la litosfera. Aquí, en la astenosfera, la roca del manto se dirige radialmente hacia afuera. Este movimiento de ascensión estaría compensado, mediante una corriente de convección, por el hundimiento lento y progresivo de material distribuído por todo el manto, que reemplazaría al material ascendente por la pluma.

pluma del manto, penacho


Definition from Wikipedia:
Fenómeno consistente en el ascenso de una estrecha columna de materiales del manto calentados, desde la base del manto terrestre hasta la base de la litosfera. Aquí, en la astenosfera, la roca del manto se dirige radialmente hacia afuera. Este movimiento de ascensión estaría compensado, mediante una corriente de convección, por el hundimiento lento y progresivo de material distribuído por todo el manto, que reemplazaría al material ascendente por la pluma.

Example sentence(s):
  • La teoría que prevalece sobre el origen de las islas de Hawaii es que los volcanes que se formaron son el resultado de una pluma del manto, un afloramiento de material caliente de las profundidades de la tierra. - Las Arterias del Volcán  

Explanation:
Si la cantidad de calor que le llega al Manto es mayor que la que puede ceder por convección se puede producir la fusión parcial del Manto, iniciándose el ascenso más rápido del material fundido. A este material caliente y fundido en ascenso se le denomina penacho o pluma del Manto.
