This session will focus on the origin of magmatism in intraplate tectonic settings. Questions to be discussed include whether such magmas form in mantle plumes or by alternative mechanisms; the nature, composition, temperature and other physical characteristics of the source; the depth of instigation, the structure, and the dynamics of plumes, etc. Contributions from the fields of geochemistry, petrology, volcanology and geodynamics will be welcome.
