  Information - GD05/TS31 Mantle Plumes, intraplate magmatism, and hotspot-ridge interaction: Geodynamical, Geophysical and Geochemical Aspects

Event Information
Large igneous provinces and hotspots represent excess volcanism that is not directly associated with the main plate tectonic cycle, and the underlying geodynamic mechanism for their generation remains unclear. Mantle plumes may be the underlying cause of both, but alternative models have been suggested. We welcome contributions for this session from a broad range of disciplines, including both observations and modeling in geology, geochemistry and geophysics, that will address questions relating to the origin and evolution of large igneous provinces, hotspots, and plumes.

Possible topics include: whether plume heads or super-plumes are required to form large igneous provinces; non-plume models for large igneous provinces and hotspots; generation and extraction of melts; temperatures and volatile-contents of melts; constraints on compositions and characteristics of mantle source regions; timing and duration of volcanism; and the stability of plumes and the hotspot reference frame.
