A mantle plume is a proposed mechanism of convection within the Earth's mantle, hypothesized to explain anomalous volcanism. Because the plume head partially...

mantle plumes has required progressive hypothesis-elaboration leading to variant propositions such as mini-plumes and pulsing plumes. Mantle plumes were...

there is a convective material circulation in the mantle. Hot material rises (in a mantle plume) while cooler (and heavier) material sinks downward...

streams of hot mantle rising from the Earth's core–mantle boundary in a structure called a mantle plume. Whether or not such mantle plumes exist has been...

the lower mantle has been shown to induce a spin transition of iron-bearing bridgmanite and ferropericlase, which may affect both mantle plume dynamics...

magnetic anomalies have been detected in the northern plains. Single plume mantle convection has also been invoked to explain the hemispheric dichotomy...

of mantle plumes beneath the EAR. Others proposed an African superplume causing mantle deformation. Although the effects of deep-rooted mantle plumes are...

refinement of the model involves the rise of a mantle plume, where abnormal heat results in melting of the upper mantle, thinning and stretching the crust, followed...

across mantle plumes, each volcano becomes inactive as it drifts off the plume, and new volcanoes are created where the plate advances over the plume. The...
