The properties of minerals and melts in the Earth’s deep mantle provide fundamental constraints on the planet’s bulk composition, mineralogy, large-scale thermal convection, and long-term geological evolution. This session invites original contributions that explore the structural, elastic, rheological, and geochemical characteristics of mantle minerals and their high-pressure phases—ranging from the upper mantle to the core-mantle boundary at depths of hundreds to thousands of kilometers.
The field is currently experiencing a transformative phase, driven by advancements in high-pressure experimental techniques—such as diamond anvil cell and large-volume press—alongside machine-learning-accelerated theoretical modeling, first-principles calculations, and the growing use of large-scale synchrotron and neutron facilities. Collectively, these approaches are revealing previously inaccessible mineral behaviors under deep Earth conditions and illuminating their atomistic mechanisms and dynamic responses.
We welcome submissions that integrate cutting-edge methodologies—from advanced numerical simulations to novel experimental and geochemical analyses—to expand our understanding of the planet’s deep interiors and redefine the current paradigms of deep Earth mineralogy.
