[SCG58-03] Modification of the subducting plate by petit-spot volcanism: Impregnation of CO2-rich melt from the asthenosphere
Keywords:CO2-rich silicate melt, metasomatic enrichment, oceanic lithosphere, petit-spot
In this presentation, we review geochemical and geochronological variation of petit-spot lava and xenocryst therein from the western North Pacific, to discuss reaction processes between CO2-rich melt and oceanic lithosphere.
