Definition

The exchange of material (magma, mantle rock) between an intraplate mantle melting anomaly (hotspot, thought to be caused in places by the presence of a mantle plume) and the global spreading ridge system. Evidence for the interaction is found in the depth of the spreading axis, its morphology, the chemistry of the lavas (both on the spreading axis and possibly at the hotspot), and sometimes by the presence of linear volcanic ridges between spreading axis and hotspot. These linear volcanic ridges generally do not show clear age-progressive volcanism, in contrast to the volcanoes of the hotspot itself.

Description

As a result of the relative fixity of hotspots with respect to the moving plates, their distance from active spreading centers changes over geological time. Depending on the plate tectonic situation, hotspots can both migrate toward and away from ridges over time, respectively, weakening and strengthening the hotspot-ridge...
