Underplating over hotspots

Article Abstract:

Analysis of the earth's crust of the Marquesas Islands confirms the presence of crustal underplating above an oceanic hotspot that is characterized by plumes of hot material arising from the Earth's mantle. Underplating involves the addition of magmatic material to the base of the crust. The hotspot of the Marquesas Island that lies on the Pacific plate has similar magnetic thickness as that of its counterpart on the Hawaiian Islands, lying on the same plate. The high-velocity material of the hotspot predominantly consists of pre-existing mantle.
