The Earth's Heterogeneous Mantle (eBook, PDF)

A Geophysical, Geodynamical, and Geochemical Perspective
Redaktion: Khan, Amir; Deschamps, Frédéric

• Format: PDF

Produktbeschreibung

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 computationsto infer the regional-scale thermo-chemical structure of the mantle.

Rezensionen

"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)
