Earth's Core: Advances in Composition, State, and Dynamics provides a detailed discussion of the Earth's core, including the composition and state of the Earth's interior, geodynamics, mineral physics, and seismic deep Earth structure. The book offers details and enhancements on existing theories, lays to rest some older theories, and inspires new theories by using observational tests, ranking conclusions, and identifying outstanding questions. The book includes detailed discussions of the core-mantle boundary, evolution of the core, compositional dynamo, and inner core phases and dynamics, offering a unique interdisciplinary perspective on what we know and what we have yet to discover.
Each chapter presents several competing theories and suggests observational tests for each one. By identifying unsolved problems with competing answers, this reference can be used to help identify and motivate further research, making it a valuable resource for researchers in deep earth geophysics, as well as many sub-disciplines, including seismology, geodynamics, geomagnetism, and mineral physics.
