This book presents the first overview of the composition and structure of the Earth’s lower mantle. The first part focuses on the study of lower-mantle minerals, identified as inclusions in diamonds from different regions of the world. Three associations are established among the lower-mantle minerals: ultramafic, mafic, and carbonatic. The carbonatic association is of particular interest because it characterizes the media of natural diamond formation. In turn, the second part analyzes the structure of the lower mantle, revealing its heterogeneous composition. It is based on the results of experiments demonstrating phase transitions in lower-mantle minerals, and on seismological data. Deep-seated earthquakes point to the presence within the lower mantle of numerous seismic boundaries caused by mineral structure transitions. In closing, the last part of the book compares observed data with experimental data, highlighting several discrepancies that indicate Earth may have a more complex planetary history than previously assumed, and examining its primarily non-chondritic composition.

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.

This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.

Constitution of the Earth's Interior discusses the physical and evolutionary principles connecting various elements of the knowledge about structure and dynamics of the Earth's interior. This work is divided into eight chapters that primarily focus on the physical, chemical, and petrological state. This text contains general data on a general stationary model, which is described by equations of state combining the basic parameters, including pressure, temperature, density, gravity acceleration, and mineral composition within the Earth's interior. Considerable chapters concern the chemical and petrological composition of the matter in the Earth's interior. The remaining chapters describe models containing inhomogeneities used to illustrate processes connected with phase transitions. This book will be of great value to geologists, physicists, and researchers.

Earth's Core: Geophysics of a Planet's Deepest Interior provides a multidisciplinary approach to Earth's core, including seismology, mineral physics, geomagnetism, and geodynamics. The book examines current observations, experiments, and theories; identifies outstanding research questions; and suggests future directions for study. With topics ranging from the structure of the core-mantle boundary region, to the chemical and physical properties of the core, the workings of the geodynamo, inner core seismology and dynamics, and core formation, this book offers a multidisciplinary perspective on what we know and what we know we have yet to discover. The book begins with the fundamental material and concepts in seismology, mineral physics, geomagnetism, and geodynamics, accessible from a wide range of backgrounds. The book then builds on this foundation to introduce current research, including observations, experiments, and theories. By identifying unsolved problems and promising routes to their solutions, the book is intended to motivate further research, making it a valuable resource both for students entering Earth and planetary sciences and for researchers in a particular subdiscipline who need to broaden their understanding. - Includes multidisciplinary observations constraining the composition and dynamics of the Earth's core - Concisely presents competing theories and arguments on the composition, state, and dynamics of the Earth's interior - Provides observational tests of various theories to enhance understanding - Serves as a valuable resource for researchers in deep earth geophysics, as well as many sub-disciplines, including seismology, geodynamics, geomagnetism, and mineral physics

A multidisciplinary perspective on the dynamic processes occurring in Earth's mantle The convective motion of material in Earth's mantle, powered by heat from the deep interior of our planet, drives plate tectonics at the surface, generating earthquakes and volcanic activity. It shapes our familiar surface landscapes, and also stabilizes the oceans and atmosphere on geologic timescales. Mantle Convection and Surface Expressions brings together perspectives from observational geophysics, numerical modelling, geochemistry, and mineral physics to build a holistic picture of the deep Earth. It explores the dynamic processes occurring in the mantle as well as the associated heat and material cycles. Volume highlights include: Perspectives from different scientific disciplines with an emphasis on exploring synergies Current state of the mantle, its physical properties, compositional structure, and dynamic evolution Transport of heat and material through the mantle as constrained by geophysical observations, geochemical data and geodynamic model predictions Surface expressions of mantle dynamics and its control on planetary evolution and habitability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
