[S-MP30] Crust-Mantle Connections

Tue. May 28, 2019 10:45 AM - 12:15 PM Poster Hall (International Exhibition Hall8, Makuhari Messe)

convener:Yoshihiko Tamura(Research Institute for Marine Geodynamics, Japan Agency for Maine-Earth Science and Technology), Osamu Ishizuka(Geological Survey of Japan, AIST), Chris Conway(Geological Survey of Japan)

A paradigm of the solid Earth geochemical cycles is that the Earth's crust forms by melting of the Earth's upper peridotitic mantle. How divers is the spectrum of primary melts and which factors may contribute to its variations? What is the influence of crustal processing vs. primary magma diversity in creating the diversity of the Earth's crust? The session seeks to explore the crust-mantle connections at divergent and convergent plate boundaries, and oceanic island settings based on volcanology, petrology, geochemistry, geophysics, geochronology, and geodynamics studies.
