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 sentences:
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)

мантийна струя
Definition from
own experience or research:
Мантийната струя е разтопена гореща маса от земната мантия, която се издига до долната част на литосферата и причинява вулканична дейност, както и деформация в централните части на литосферните плочи.
Example sentences:
Лавите на вулкана принадлежат на типична вътрешноплочова алкална серия: високо TiO2 съдържание (2,4-3,7 wt.%), Na2O между 2,9 и 5,2 wt.%, K2O между 1,1 и 3,0 wt.%. Съдържанията и поведението на елементите-следи сочат фракционната кристализация като основен фактор при еволюцията на магмата и източник – мантийна струя (plume). (The Mount Cameroon stratovolcano (Camero)
"Алкални базалти от кратонните плато-базалти в Патагония и от атлантическия остров Възнесение са използвани за сравнение и тяхната геохимия е подобна на свързаните с мантийна струя базалти на MBL. (The olivine basalts from Livingston Isla)
