Deep Earth: Physics and Chemistry of the Lower Mantle and Core highlights recent advances and the latest views of the deep Earth from theoretical, experimental, and observational approaches and offers insight into future research directions on the deep Earth. In recent years, we have just reached a stage where we can perform measurements at the conditions of the center part of the Earth using state-of-the-art techniques, and many reports on the physical and chemical properties of the deep Earth have come out very recently. Novel theoretical models have been complementary to this breakthrough. These new inputs enable us to compare directly with results of precise geophysical and geochemical observations. This volume highlights the recent significant advancements in our understanding of the deep Earth that have occurred as a result, including contributions from mineral/rock physics, geophysics, and geochemistry that relate to the topics of:

I. Thermal structure of the lower mantle and core

II. Structure, anisotropy, and plasticity of deep Earth materials

III. Physical properties of the deep interior

IV. Chemistry and phase relations in the lower mantle and core

V. Volatiles in the deep Earth

The volume will be a valuable resource for researchers and students who study the Earth's interior. The topics of this volume are multidisciplinary, and therefore will be useful to students from a wide variety of fields in the Earth Sciences.

Hidenori Terasaki is a Professor in the Department of Earth and Space Science at Osaka University. Hidenori’s research focuses on studying the earth interior composition, with particular emphasis on measuring density, viscosity, interfacial tension, temperature and pressure related to mantle and core properties and formation. He is a recipient of the young scientist research award in the Mineralogical Society of Japan and Japan Society of High Pressure Science and Technology. He is a member of the American Geophysical Union, The Japan Society of High Pressure Science and Technology, The Iron and Steel Institute of Japan, Japan Association of Mineralogical Sciences and The Japanese Society for Planetary Science. Rebecca Fischer is a PhD candidate in the Department of the Geophysical Sciences at the University of Chicago. Her research focuses on the formation and chemical evolution of the Earth, with particular focus emphasis on the physical and chemical properties of minerals and melts at extreme conditions. She uses diamond anvil cells and laser-heating to experimentally recreate the high pressures (up to >150 GPa) and high temperatures (several thousand K) of the Earth’s deep interior, combined with numerical simulations of accretion. She has been the recipient of organizational fellowships and scholarships (NSF) for her scholarly research on the Interior of the Earth.
