Mantle Plumes - What Do We Really Know?

Explore the latest research on mantle plumes in this comprehensive conference session from the 2012 AGU Fall Meeting. Delve into topics ranging from Hawaiian volcano compositions and geochemical variations to the origins of chemical heterogeneity in mantle plumes. Examine age and melt flux variations along the Hawaiian Ridge, and compare the Galapagos and Easter hotspots. Investigate geochemical provincialism in ocean islands, with a focus on Iceland, and analyze plume source regions in the South Atlantic. Gain insights into isotopic diversity and its implications for plume strength. Through a series of invited talks and research presentations, uncover the current state of knowledge on mantle plumes and their role in shaping Earth's geology.
