Environmental and Low-Temperature Geochemistry presentsconceptual and quantitative principles of geochemistry in order tofoster understanding of natural processes at and near theearth’s surface, as well as anthropogenic impacts on the natural environment. It provides the reader with theessentials of concentration, speciation and reactivity of elementsin soils, waters, sediments and air, drawing attention to boththermodynamic and kinetic controls. Specific featuresinclude: • An introductory chapter that reviews basic chemicalprinciples applied to environmental and low-temperaturegeochemistry • Explanation and analysis of the importance of minerals inthe environment • Principles of aqueous geochemistry • Organic compounds in the environment • The role of microbes in processes such asbiomineralization, elemental speciation and reduction-oxidationreactions • Thorough coverage of the fundamentals of importantgeochemical cycles (C, N, P, S) • Atmospheric chemistry • Soil geochemistry • The roles of stable isotopes in environmentalanalysis • Radioactive and radiogenic isotopes as environmentaltracers and environmental contaminants • Principles and examples of instrumental analysis inenvironmental geochemistry The text concludes with a case study of surface water andgroundwater contamination that includes interactions and reactionsof naturally-derived inorganic substances and introduced organiccompounds (fuels and solvents), and illustrates theimportance of interdisciplinary analysis in environmentalgeochemistry. Readership: Advanced undergraduate and graduate studentsstudying environmental/low T geochemistry as part of an earthscience, environmental science or related program.

Volume 49 of Reviews in Mineralogy and Geochemistry reviews the state of the art of synchrotron radiation applications in low temperature geochemistry and environmental science, and offer speculations on future developments. The reader of this volume will acquire an appreciation of the theory and applications of synchrotron radiation in low temperature geochemistry and environmental science, as well as the significant advances that have been made in this area in the past two decades. It gives a fairly comprehensive overview of synchrotron radiation applications in low temperature geochemistry and environmental science, describes the ways that synchrotron radiation is generated, including a history of synchrotrons and a discussion of aspects of synchrotron radiation that are important to the experimentalist, describes specific synchrotron methods that are most useful for single-crystal surface and mineral-fluid interface studies as well as methods that can be used more generally for investigating complex polyphase fine-grained or amorphous materials, including soils, rocks, and organic matter.

Low-temperature geochemistry -- a 'hot topic' in geochemistry at present -- deals with geological and chemical processes and the geochemical evolution of elements in nature below 200C, including the geochemical behaviour of elements in the processes of their extraction, remobilization, transport and mineralization at room temperature and below 0C. This book focuses on the low-temperature geochemical behaviour of precious metals, REE, some individual dispersed elements and some non-metallic elements and their minergenesis at low-temperatures. The book deals with the following topics: 1) geochemistry of selected low-temperature deposits or prospects (horizons); 2) geochemistry of elements during diagenesis, buried metamorphism and low-grade metamorphism; 3) remobilization, transport and precipitation of some ore-forming elements under low-temperature conditions; 4) water/rock interactions in low-temperature open systems

The Treatise on Geochemistry is the first work providing a comprehensive, integrated summary of the present state of geochemistry. It deals with all the major subjects in the field, ranging from the chemistry of the solar system to environmental geochemistry. The Treatise on Geochemistry has drawn on the expertise of outstanding scientists throughout the world, creating the reference work in geochemistry for the next decade. Each volume consists of fifteen to twenty-five chapters written by recognized authorities in their fields, and chosen by the Volume Editors in consultation with the Executive Editors. Particular emphasis has been placed on integrating the subject matter of the individual chapters and volumes. Elsevier also offers the Treatise on Geochemistry in electronic format via the online platform ScienceDirect, the most comprehensive database of academic research on the Internet today, enhanced by a suite of sophisticated linking, searching and retrieval tools.

An examination of both theoretical and practical approaches to the geochemistry of natural waters with a more tightly focused emphasis on fresh-water environments. The third edition focuses more on environmental issues than the previous edition, reflecting the importance on environmental geochemistry as a result of increased environmental awareness and regulatory requirements. Prepares readers to interpret the probable cause of a particular water composition and to predict the probable water chemistry in those situations where data do not exist.

The Earth system consists of subsystems that include the atmosphere, hydrosphere (water), geosphere (rocks, minerals), biosphere, and humans. In order to understand these subsystems and their interactions, it is essential to clarify the mass transfer mechanism, geochemical cycle, and influence of human activity on the natural environment. This book presents fundamental theories (thermodynamics, kinetics, mass balance model, coupling models such as the kinetics-fluid flow model, the box model, and others) concerning mechanisms in weathering, formation of hydrothermal ore deposits, hydrothermal alteration, formation of groundwater quality, and the seawater system. The interaction between fluids (atmosphere, water) and solid phases (rocks, minerals) occurs both in low-temperature and also in high-temperature systems. This book considers the complex low-temperature cycle with the high-temperature cycle, a combination that has not been dealt with in previous books concerning Earth systems. Humanity is a small part of the biosphere; however, human activities greatly influence Earth’s surface environments (atmosphere, hydrosphere, biosphere, soils, rocks). Thus, the influences of humans on other subsystems, particularly mass transfer in the deep underground geologic environment composed of host rocks and groundwater, are discussed in relation to high-level nuclear waste geologic disposal and CO2 underground sequestration—topics that have not been included in other books on environmental science.

In a sense, all mineralogy is environmental mineralogy. However, the term environmental has come to be employed (particularly in combination with terms such as science, issue or problem) to refer to those systems at or near the surface of the Earth where the geosphere comes into contact with the hydrosphere, atmosphere and biosphere. This is, of course, the environment upon which the human race depends for survival and, hence, is now sometimes referred to as the critical zone. Those systems containing minerals that constitute the most important or key environments are considered here: soils, modern sediments, atmospheric aerosols, and the interior or exterior parts of certain micro- and macro-organisms. Particularly important are the roles that minerals play in processes that act over time to control or influence the environment at various scales of observation. Both pure systems and those contaminated as a result of human activity are considered. The objectives for this volume are to help to define the subject of environmental mineralogy, and to provide an initial source of information both for mineralogists and other scientists who wish to understand or work in this field. It was hoped that it might also provide a text for use by those teaching courses in the subject at advanced undergraduate or graduate student level.
