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

plaštna perjanica

Definition from Wikipedia:
Plaštne perjanice su izdiruće i nadprosječno vruće stijene unutar Zemljinog omotača.

Example sentence(s):
  • Okoliši u kojima nastaje magma te sastav nastale magme, povezani su. Ti okoliši uključuju zone subdukcije, zone kontinentalnog brazdanja (eng. continental rifting), srednjeoceanske hrptove te vruće točke, do kojih su neke interpretirane kao plaštne perjanice (eng. mantle plumes). - Wikipedia  
  • Plaštne perjanice (engl. mantle plumes) vrše udare na donjoj strani tektonskih ploča pa mogu drastično promijeniti topografiju oceanskog dna. ... - Mekušci  
  • Dok smo zacudjeno promatrali, šest aktivnih perjanica je izbacivalo plinove i fine čestice na nebo. Najveći od njih, koji se sada zove Pelé, prema havajskoj bozžici vulkana, izbacivao je vodoskok materijala 250 kilometara u svemir, - Vjesnik  

S tim u vezi je i termin "vruća točka" (hot spot):
