A textbook for graduate students and researchers in geology, geophysics, materials science, mineralogy and ceramics.A comprehensive, unified treatment of the materials science of deformation as applied to solid Earth geophysics and geology, this textbook is ideal for graduate courses on the rheology and dynamics of solid Earth. It is also a much-needed reference for geoscientists in geology, geophysics, geochemistry, materials science, mineralogy and ceramics.A comprehensive, unified treatment of the materials science of deformation as applied to solid Earth geophysics and geology, this textbook is ideal for graduate courses on the rheology and dynamics of solid Earth. It is also a much-needed reference for geoscientists in geology, geophysics, geochemistry, materials science, mineralogy and ceramics.This graduate textbook presents a comprehensive, unified treatment of the materials science of deformation as applied to solid Earth geophysics and geology. The deformation of Earth materials is presented in a systematic way covering elastic, anelastic and viscous deformation. Advanced discussions on relevant debates are also included to bring readers a full picture of science in this interdisciplinary area. This textbook is ideal for graduate courses on the rheology and dynamics of solid Earth, and includes review questions with solutions so readers can monitor their understanding of the material presented. It is also a much-needed reference for geoscientists in many fields including geology, geophysics, geochemistry, materials science, mineralogy and ceramics.Part I. General Background: 1.
