The structure, composition and dynamics of Earth’s mantle through intraplate volcanism

Session ID#: 79413

Session Description:
Volcanism in oceanic and continental intraplate settings provides a unique insight into the thermal and compositional structure of Earth’s mantle. Compositional variability of mantle melts stems from a combination of source heterogeneity, partial melting and extraction. Superimposed on these primary mantle melt compositions are the effects of assimilation, magma mixing and crystallization during residence and transport through often complex ‘plumbing’ systems in the lithosphere. These processes are evident at different spatial and temporal scales and confound our ability to connect surface observations from flood basalt provinces, ocean islands and other regions of intraplate volcanism to the structure of the mantle, its dynamic behaviour and chemical evolution. In this interdisciplinary session we seek novel approaches aimed at using the message from intraplate volcanism to understand the thermal and compositional structure of the mantle. We encourage researchers whose work on intraplate volcanism has implications that reach beyond disciplinary lines.
