The Earth's Heterogeneous Mantle
Description
This book highlights and discusses recent developments that have contributed to an improved understanding of observed mantle heterogeneities and their relation to the thermo-chemical state of Earth's mantle, which ultimately holds the key to unlocking the secrets of the evolution of our planet. This series of topical reviews and original contributions address 4 themes. Theme 1 covers topics in geophysics, including global and regional seismic tomography, electrical conductivity and seismic imaging of mantle discontinuities and heterogeneities in the upper mantle, transition zone and lower mantle. Theme 2 addresses geochemical views of the mantle including lithospheric evolution from analysis of mantle xenoliths, composition of the deep Earth and the effect of water on subduction-zone processes. Theme 3 discusses geodynamical perspectives on the global thermo-chemical structure of the deep mantle. Theme 4 covers application of mineral physics data and phase equilibrium computations to infer the regional-scale thermo-chemical structure of the mantle.

"This book focuses on the most up-to-date developments and insights into the earth's mantle and the extent of its radial and lateral heterogeneities, which range from the microscopic to megascopic. . this book should be on the shelf, if not the desk, of anyone with an academic interest in the Earth's mantle . . Summing Up: Essential. Graduate students, faculty/researchers, and professionals/practitioners." (M. S. Field, Choice, Vol. 53 (2), October, 2015)
