  2. Mantle plume - Wikipedia

    en.wikipedia.org/wiki/Mantle_plume

    However, paleomagnetic data show that mantle plumes can also be associated with Large Low Shear Velocity Provinces (LLSVPs) [7] [8] and do move relative to each other. [9] The current mantle plume theory is that material and energy from Earth's interior are exchanged with the surface crust in two distinct and largely independent convective flows:

  3. Plume tectonics - Wikipedia

    en.wikipedia.org/wiki/Plume_tectonics

    Plume tectonics is a geoscientific theory that finds its roots in the mantle doming concept which was especially popular during the 1930s and initially did not accept major plate movements and continental drifting. It has survived from the 1970s until today in various forms and presentations.

  4. Mantle convection - Wikipedia

    en.wikipedia.org/wiki/Mantle_convection

    Mantle convection is the very slow creep of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. [2] [3] Mantle convection causes tectonic plates to move around the Earth's surface. [4] The Earth's lithosphere rides atop the asthenosphere, and the two form the components of the upper mantle ...

  5. Earth's crustal evolution - Wikipedia

    en.wikipedia.org/wiki/Earth's_crustal_evolution

    The formation and development of plumes in the early mantle contributed to triggering the lateral movement of crust across the Earth's surface. [18] The effect of upwelling mantle plumes on the lithosphere can be seen today through local depressions around hotspots such as Hawaii. The scale of this impact is much less than that exhibited in the ...

    After 60 years of trying, geologists finally pried rocks from Earth's upper mantle. That's huge for so many reasons.

  7. Hotspot (geology) - Wikipedia

    en.wikipedia.org/wiki/Hotspot_(geology)

    It was later postulated that hotspots are fed by streams of hot mantle rising from the Earth's core–mantle boundary in a structure called a mantle plume. [6] Whether or not such mantle plumes exist has been the subject of a major controversy in Earth science, [4] [7] but seismic images consistent with evolving theory now exist. [8]

  8. Large igneous province - Wikipedia

    en.wikipedia.org/wiki/Large_igneous_province

    Earth has an outer shell made of discrete, moving tectonic plates floating on a solid convective mantle above a liquid core. The mantle's flow is driven by the descent of cold tectonic plates during subduction and the complementary ascent of mantle plumes of hot material from lower levels. The surface of the Earth reflects stretching ...

    A professor at Delaware State University, Dr. Gabriel Gwanmesia, received a $672,000 grant to study the minerals in the Earth's mantle, hundreds of miles beneath the surface, and he recently ...
