Mantle plume information

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

of Iceland is attributed to this plume, according to the theory of W. Jason Morgan. It is believed that a mantle plume underlies Iceland, of which the...

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

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...

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

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

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...

the Anahim hotspot might be supplied by a mantle plume from the upper mantle rather than a deep-seated plume proposed by Wilson. Tomographic imaging has...
