Geochemical Thermodynamics
by Darrell Kirk Nordstron James L. MunozGeochemical Thermodynamics (Second Edition), first published in 1994, takes the reader beyond the fundamental principles of thermodynamics to true geochemical applications. You will find the most complete coverage of the phase rule, chemography, solid solutions, ionic activities in the mixed aqueous electrolytes, and chemical potential diagrams for multiphase systems, plus other concepts central to geochemical theory. Throughout, there is an emphasis on environmentally relevant examples and applications. New sections include: - thermobarometry applications for igneous and metamorphic rocks; -expanding information on electrolytes at high temperature and pressure; - a new chapter on geochemical modeling; and substantially updated and expanded references. - a new appendix containing internally consistent enthalpies, entropies, heat capacities, and free energies, and equilibrium constants for a limited number of elements, ions, non-silicate minerals, and reactions at 298. 15K and 1 atmosphere that are particularly useful for hydrogeochemical modeling. 'This book presents the thermodynamics of geochemical systems, with applications ranging from groundwater to magmas. It should be of interest to a large number of such scientists wishing better acquaintance with the application of thermodynamics to practical problems. Geology There is a good balance of theory and application, and the book is superior to any other available text at the graduate or undergraduate level I can strongly recommend this book, having used it for a third-year undergraduate geochemistry course. It is most appropriate for physical geochemistry course with an emphases on thermodynamics. Researchers in petrology oriented fields will also find the book useful Canadian Mineralogist
Geochemical Treasures and Petrogenetic Processes
by John S. Armstrong-Altrin Kailasa Pandarinath Sanjeet Kumar VermaThis book highlights various aspects of geochemical and geological processes. In brief, it facilitates to understand the geochemical behavior of major, trace and rare earth elements in rocks to identify the magmatic processes involved in present-day magma generation and their relation to global tectonic regimes as well as geothermal studies. Therefore, the book provides a comprehensive view of the generation of magma types (mafic to felsic in composition) and their role in the petrogenesis. The book also covers the development of new geosoftware to effectively process the geochemical data before its interpretation.
Geochemistry
by Francis AlbarèdeIntroducing the essentials of modern geochemistry for students across the Earth and environmental sciences, this new edition emphasises the general principles of this central discipline. Focusing on inorganic chemistry, Francis AlbarÉde's refreshing approach is brought to topics that range from measuring geological time to the understanding of climate change. The author leads the student through the necessary mathematics to understand the quantitative aspects of the subject in an easily understandable manner. The early chapters cover the principles and methods of physics and chemistry that underlie geochemistry, to build the students' understanding of concepts such as isotopes, fractionation, and mixing. These are then applied across many of the environments on Earth, including the solid Earth, rivers, and climate, and then extended to processes on other planets. Three new chapters have been added – on stable isotopes, biogeochemistry, and environmental geochemistry. End-of-chapter student exercises, with solutions available online, are also included.
Geochemistry
by William M. WhiteThis book provides a comprehensive introduction to the field of geochemistry. The book first lays out the 'geochemical toolbox': the basic principles and techniques of modern geochemistry, beginning with a review of thermodynamics and kinetics as they apply to the Earth and its environs. These basic concepts are then applied to understanding processes in aqueous systems and the behavior of trace elements in magmatic systems. Subsequent chapters introduce radiogenic and stable isotope geochemistry and illustrate their application to such diverse topics as determining geologic time, ancient climates, and the diets of prehistoric peoples. The focus then broadens to the formation of the solar system, the Earth, and the elements themselves. Then the composition of the Earth itself becomes the topic, examining the composition of the core, the mantle, and the crust and exploring how this structure originated. A final chapter covers organic chemistry, including the origin of fossil fuels and the carbon cycle's role in controlling Earth's climate, both in the geologic past and the rapidly changing present.Geochemistry is essential reading for all earth science students, as well as for researchers and applied scientists who require an introduction to the essential theory of geochemistry, and a survey of its applications in the earth and environmental sciences.Additional resources can be found at: www.wiley.com/go/white/geochemistry

Geochemistry at the Earth's Surface
by Andreas Bauer Bruce D. VeldeGeochemistry at the surface of the earth is dominated by two somewhat antagonistic forces: chemical reactions which attempt to attain a steady state (equilibrium) and geological movement of materials in time and space which changes the parameters that control chemical equilibrium. Another aspect that is extremely important to earth surface geochemistry is the effect of plants on the chemical and physical stability of materials (soils). Plant systems in fact work against the normal chemical changes (loss of silica, potassium, etc. ) and the normal physical changes (stabilizing fine grained materials (clays) in the surface zones to avoid erosion). Biological effects are clearly seen in redox effects in the various parts of the earth surface movement cycle; soil formation, stream transport, sedimentation. This book attempts to outline these different parameters and their interactions as they affect earth surface geochemistry in order to give a better understanding of movement and accumulation of elements at the surface of the earth.
Geochemistry of Chromium in the Earth’s Mantle (Springer Geology)
by Ekaterina A. Matrosova Andrey V. Bobrov Luca BindiThis book provides an analysis of an actual problem of the evolution of deep matter under the conditions of the upper mantle, transition zone, and uppermost lower mantle. This issue has a fundamental importance in geochemistry, petrology, mineralogy, and crystalochemistry of the mantle, at different depths. The authors discuss new experimental research on the composition and conditions of the chromium-bearing minerals genesis and their associations in the Earth’s mantle. The experimental data are compared with the natural mineral assemblages, allowing a refinement of the structure and composition of the deep Geospheres of the Earth. The results of the physicochemical experiments in the "MgO–SiO2–Cr2O3" model and the multicomponent systems play a major role in understanding the phase diagrams of these systems, the structural patterns of chromium-bearing phases and the influence of Cr on P-T parameters in the Earth’s mantle.

Geochemistry: Pathways and Processes
by Maria Uhle Harry McSween Steven RichardsonWritten expressly for undergraduate and graduate geologists, this book focuses on how geochemical principles can be used to solve practical problems. The attention to problem-solving reflects the authors'belief that showing how theory is useful in solving real-life problems is vital for learning. The book gives students a thorough grasp of the basic principles of the subject, balancing the traditional equilibrium perspective and the kinetic viewpoint. The first half of the book considers processes in which temperature and pressure are nearly constant. After introductions to the laws of thermodynamics, to fundamental equations for flow and diffusion, and to solution chemistry, these principles are used to investigate diagenesis, weathering, and natural waters. The second half of the book applies thermodynamics and kinetics to systems undergoing changes in temperature and pressure during magmatism and metamorphism. This revised edition incorporates new geochemical discoveries as examples of processes and pathways, with new chapters on mineral structure and bonding and on organic matter and biomarkers. Each chapter has worked problems, and the authors assume that the student has had a year of college-level chemistry and a year of calculus.Praise for the first edition"A truly modern geochemistry book.... Very well written and quite enjoyable to read.... An excellent basic text for graduate level instruction in geochemistry." —Journal of Geological Education"An up-to-date, broadly conceived introduction to geochemistry.... Given the recent flowering of geochemistry as an interdisciplinary science, and given the extent to which it now draws upon the fundamentals of thermodynamics and kinetics to understand earth and planetary processes, this timely and rigorous [book] is welcome indeed." —Geochimica et Cosmochimica Acta

Geochronology in Canada (The Royal Society of Canada Special Publications #No. 8)
by Freleigh OsborneThis volume is made up of papers presented at a colloquium of the Geology Devision of Section III of the Royal Society of Canada at the annual meeting in Quebec, June 1963. The papers fall into two groups: in one group the validity and shortcomings of the methods of establishing the geographical time-table are discussed; and, in the other, applications of the methods to areas across Canada, and from Precambrian to recent, are described. The geological time-table has been built up from the record of the rocks and is based on the law of superposition, a fact that is pointed out in the first paper of this volume. The chronological value of fossils, palaeomagnetism as a means of dating geological events, the limitations of radiometric dating, and other pertinent matters are here dealth with by a group of well-known authorities. These scientific disquisitions will be of great importance to geologists everywhere.This work should be of special interest to those engaged in research on the history of the earth, particularly in relation to the nature, the causes, and the time of an event. It will also serve as a valuable reference to practising geologists in government or industry, to university departments of geology, and to geological consultants.

Geoconservation and Geotourism Potential of India (Society of Earth Scientists Series)
by Satish C. Tripathi Naresh Chandra Pant Sameeta RajoraIndia is blessed with great geological diversity as it has recorded more than 3.5 billion year’s history of evolution of Earth, some of the sites/sections are unique to the globe. The recent discovery of youngest ‘Meghalayan age’ from a limestone cave of Meghalaya is internationally recognised. The Indian rock record bears the signatures of various global geological events including evolution of life, mass extinction, making of Himalaya, meteoritic impact craters etc. Indian dinosaur 'Rajasaurus' created curiosity in the children. Interestingly, large number of geoheritage sites are associated with well-known cultural heritage sites and biodiversity hotspots. However, proper scientific details of geoheritage sites and their potential to develop as a geotourism hotspot has not been discussed. Geotourism potential of India in extensive but so far it has not attracted attention of authorities and agencies of the Tourism sector. The present book provides a platform for them to plan and explore. Development of geotourism will lead to conservation of geoheritage sites and both financial and scientific aspects will be covered.
Geocryology: Characteristics and Use of Frozen Ground and Permafrost Landforms
by Stuart A. Harris Anatoli Brouchkov Cheng GuodongThis book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature. Finalist of the 2019 PROSE Awards.
Geocultural Power: China's Quest to Revive the Silk Roads for the Twenty-First Century (Silk Roads)
by Tim WinterLaunched in 2013, China's Belt and Road Initiative is forging connections in infrastructure, trade, energy, finance, tourism, and culture across Eurasia and Africa. This extraordinarily ambitious strategy places China at the center of a geography of overland and maritime connectivity stretching across more than sixty countries and incorporating almost two-thirds of the world’s population. But what does it mean to revive the Silk Roads for the twenty-first century? Geocultural Power explores this question by considering how China is couching its strategy for building trade, foreign relations, and energy and political security in an evocative topography of history. Until now Belt and Road has been discussed as a geopolitical and geoeconomic project. This book introduces geocultural power to the analysis of international affairs. Tim Winter highlights how many countries—including Iran, Sri Lanka, Kenya, Malaysia, Indonesia, Pakistan, and others—are revisiting their histories to find points of diplomatic and cultural connection. Through the revived Silk Roads, China becomes the new author of Eurasian history and the architect of the bridge between East and West. In a diplomatic dance of forgetting, episodes of violence, invasion, and bloodshed are left behind for a language of history and heritage that crosses borders in ways that further the trade ambitions of an increasingly networked China-driven economy.
Geodesign by Integrating Design and Geospatial Sciences
by Henk J. Scholten Danbi J. Lee Eduardo DiasIn Europe, the emerging discipline of geodesign was earmarked by the first Geodesign Summit held in 2013 at the GeoFort, the Netherlands. Here researchers and practitioners from 28 different countries gathered to exchange ideas on how to merge the spatial sciences and design worlds This book brings together experiences from this international group of spatial planners, architects, landscape designers, archaeologists, and geospatial scientists to explore the notion of 'Geodesign thinking', whereby spatial technologies (such as integrated 3D modelling, network analysis, visualization tools, and information dashboards) are used to answer 'what if' questions to design alternatives on aspects like urban visibility, flood risks, sustainability, economic development, heritage appreciation and public engagement The book offers a single source of geodesign theory from a European perspective by first introducing the geodesign framework, then exploring various case studies on solving complex, dynamic, and multi-stakeholder design challenges This book will appeal to practitioners and researchers alike who are eager to bring design analysis, intelligent planning, and consensus building to a whole new level
Geodesigning Our Future: Urban Development Dynamics in Israel (The Urban Book Series)
by Shlomit Flint AsheryThis book examines how map-based collaboration software can facilitate negotiations in areas undergoing contentious pressures for significant change. Based on case studies from Israel, it aims to introduce a useful model of planning implementation as an outcome of complex interaction to reduce the gap between planning and urban reality. It puts an analytical realist foundation for a productive discussion of the role of future planning and bares meaningful scientific contributions to the general frame of the negotiating process and implementation, which still needs further research and elaboration.Geodesign, a cutting-edge planning approach that is rooted in the history of planning practice, has become one of the most popular approaches for sustainable planning and design activities after 2000s. Planners tend to think of design at a site scale, but geodesign covers a variety of scales, bridging the gap between the regional and the local contexts.This is important because to be practically effective and politically prudent, "smart growth" plans need to make sense across a spectrum of scales and disciplines. This ranges from design, urban design, community planning, town and city planning, and regional planning, up to planning for mega-regions.
Geodesy
