Dear Colleagues,

We would like to draw your attention to an AGU session titled: “Turning Earth Inside Out: Large Igneous Provinces, Mantle Plumes, and the Co-Evolution of Earth's Interior and Surface Environments” Session V017

Description: Voluminous Large Igneous Province (LIP) magmatism represents a large-scale end-member for volcanic activity on Earth, and has coincided with major shifts in Earth’s surface chemistry, climate, and biota. LIP magmas serve as couriers from the deep mantle, and in some cases from the subcontinental lithosphere. Finally, carbon outgassing during LIPs serves as one of the few potential geological analogs for the scale of present-day anthropogenic carbon release. This multi-disciplinary session will showcase recent advances in understanding the physical, chemical, and redox evolution of the deep mantle sources of LIPs and mantle plumes, the mobilization of volatiles, the tempo and nature of LIP magmatic activity and the relationship with geodynamics, and how these aspects of the life cycle of LIPs relate to state-of-the-art records of paleo-environmental changes. We welcome contributions from petrology, seismology, geochemistry, geochronology, volcanology, paleoclimatology—and especially a combination of these fields—that aim to provide new perspectives on how LIPs work, and how they serve as a coupling mechanism between the evolution of the mantle and surface environments through Earth’s history.

Invited Presenters:

Judy Pu – University of California Santa Barbara

Xiaochuan Tian – Boston College

The deadline for abstract submission is August 3rd 23:59 EDT.

We hope you can join us!
