Rare Earth Elements in Groundwater Flow Systems is the first volume of its kind entirely focused on the geochemistry of the lanthanide series elements in groundwater/aquifer environments. Consisting of ten chapters, each of which is an original, peer-reviewed contribution by some of the leading researchers in the study of the low-temperature geochemistry of rare earth elements, the volume addresses analytical techniques, water-rock interactions, aqueous complexation, and the reactions/processes that influence these heavy metals along groundwater flow paths.

This book reviews current ideas explaining the formation of granite in terms of melting, segregation, ascent and emplacement. It introduces an alternative hypothesis that granites are endogenic in that they essentially form and remain at melting sites in the middle upper crust under conditions of abnormally high heat flow. The book highlights results of Chinese research over the last 30 years in English for the first time.

This book focuses on sediments as a pollutant in natural freshwater and marine habitats, and as a vector for the transfer of chemicals such as nutrients and contaminants. Sediment-water research is carried out all over the world within a variety of disciplines. The selected papers cover three main topics:
-assessment and/or restoration of disturbed watersheds
-sediment-water linkages in terrestrial and aquatic environments
-evaluation of sediment and ecological changes in marine and freshwater habitats.

Innovative research in both developed and less developed countries is included and both fundamental research and insight into applied research and system management are covered.

This book will be of interest to graduate students, researchers, catchment managers and government regulators working within many areas of education, protection and management of the environment, including sediment geochemistry and dynamics, aquatic habitats, water quality, aquatic ecology, river morphology, restoration techniques and catchment management.

Mechanochemistry as a branch of solid state chemistry enquires into processes which proceed in solids due to the application of mechanical energy. This provides a thorough, up to date overview of mechanochemistry of solids and minerals. Applications of mechanochemistry in nanoscience with special impact on nanogeoscience are described. Selected advanced identification methods, most frequently applied in nanoscience, are described as well as the advantage of mechanochemical approach in minerals engineering. Examples of industrial applications are given. Mechanochemical technology is being applied in many industrial fields: powder metallurgy (synthesis of nanometals, alloys and nanocompounds), building industry (activation of cements), chemical industry (solid waste treatment, catalyst synthesis, coal ashes utilization), minerals engineering (ore enrichment, enhancement of processes of extractive metallurgy), agriculture industry (solubility increase of fertilizers), and pharmaceutical industry (improvement of solubility and bioavailability of drugs).

This reference serves as an introduction to newcomers to mechanochemistry, and encourages more experienced researchers to broaden their knowledge and discover novel applications in the field.

This textbook gives a concise introduction to modern crystal structure determination, emphasising both its theoretical background and the way it is actually carried out. The theoretical sections are supported by many illustrations, and lay emphasis on a good understanding rather than rigorous mathematics. The most important data collection techniques, and the methods of data reduction, structure solution and refinement are discussed from a practical point of view. Many tips and insights help readers to recognise and avoid possible errors and traps, and to judge the quality of results. The second edition has been considerably updated, especially the chapter on experimental methods, which is now mainly concerned with modern data collection using area-detectors.

Lessons in Environmental Microbiology provides an understanding of the microbial processes used in the environmental engineering and science fields. It examines both basic theory as well as the latest advancements in practical applications, including nutrient removal and recovery, methanogenesis, suspended growth bioreactors, and more. The information is presented in a very user-friendly manner; it is not assumed that readers are already experts in the field. It also offers a brief history of how microbiology relates to sanitary practice, and examines the lessons learned from the great epidemics of the past. Numerous worked example problems are presented in every chapter.

Dramatic advances in understanding global tectonics have been made in the last half century and the information and specific data acquired on the floor of the World Ocean by the scientific community probably has exc- ded that available in all previous time. With the benefit of new technology and advanced concepts in the earth sciences extensive exploration of the deep seabed became possible, and has been carried out in many parts of the world. Many features have been recognized and data recorded that are vital for understanding the fundamental processes that shape the earth=s surface and control the habitable environment. The data collected to date on the o- an floor and its physical environment greatly exceeds our understanding and appreciation of their fundamental importance in the earth sciences, and our ability to apply this knowledge effectively in improving our way of life. With his extensive scientific knowledge and unique experience from - ny cruises in association with scientists throughout the world, Dr. Evgeny Gurvich has made an outstanding contribution in acquiring basic data on hydrothermal and sedimentation processes in the ocean, as well as in the synthesis of data and concepts available from cruise reports and an extensive literature.

The Legacy of Carbon Dioxide: Past and Present Impacts covers the truly varied roles carbon dioxide has played and continues to play in the character of our planet. Chapters address the synthesis of CO2 in stars, the evolution of the atmosphere over billions of years, the chemical and physical properties of CO2 and how those influence common phenomena. How well this knowledge is understood and how it was determined, including existing uncertainties in our confidence and the stress from competing possibilities are discussed. Much of the technological jargon in various incorporated sciences has been modified to ease consumption by the non-expert. Features: Provides a historical panorama on how much the world has changed over the eons and the vast influence of carbon dioxide in these changes Follows CO2 through acidic explosive waters, volcanic episodes, sequestered reservoirs, and the chemistry of life Examines the broad scope of chemical and physical attributes carbon dioxide is capable of and their impacts Much of the technological verbiage in various incorporated sciences has been modified to ease consumption by the non-expert. This book is a valuable resource for readers interested in the science of carbon dioxide as well as natural science, the environment, scientific methods, chemistry, and geological sciences.

Introducing 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 Albarede'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.

The first part of this book reviews the basics of atmospheric chemistry, radiation transport, and optical spectroscopy before detailing the principles underlying DOAS. The second part describes the design and application of DOAS instruments as well as the evaluation and interpretation of spectra. The recent expansion of DOAS application to the imaging of trace gas distributions by ground, aircraft, and satellite-based instruments is also covered.

When Darwin wrote his Origin of Species, one of his main concerns was with the perceived shortness of the fossil record of life. Until the work of J. William Schopf and his colleagues, much of this history was thought to be unknowable. This book, through a memoire of Schopf's personal recollections, documents astonishing discoveries revealing the first 85% of the history of life. These earliest periods of life on Earth emerge as a tale of individual and internationally collaborative exploration told by a scholar whose 60 years of research contributed to the recognition of the richness and diversity which forms the foundation of today's biodiversity. Key Features Documents, through personal narrative, a paradigm shift is the study of the earliest life Summarizes a fossil record largely unknown until relatively recently Addresses one of Darwin's most troubling concerns about his theory of natural selection Predicts future developments in the study of first life

Extreme weather and climate change aggravate the frequency and magnitude of disasters. Facing atypical and more severe events, existing early warning and response systems become inadequate both in scale and scope. Earth Observation (EO) provides today information at global, regional and even basin scales related to agrometeorological hazards. This book focuses on drought, flood, frost, landslides, and storms/cyclones and covers different applications of EO data used from prediction to mapping damages as well as recovery for each category. It explains the added value of EO technology in comparison with conventional techniques applied today through many case studies.

The current scenario provides an ideal opportunity to confer higher priority to the marine resources of the Indian Ocean, particularly in terms of integrated management of the deep sea, shallow sea and coastal resources. This will maximize their potential in the sustainable development goal (SDG) pattern, leading to an appropriate environmental management. Therefore, this book aims to provide an overview of the area and to highlight the potential market opportunities represented by this vast and rapidly developing nation. In doing so the following aspects have been covered: Exclusive title focussing on mineral resources of Indian ocean. Discusses living, nonliving, ocean waves and tidal energy, ocean environment and protection aspects. Includes information on key themes, details of organizations associated with the Indian Ocean. Illustrates deep sea mining technology and environmental perspectives. Covers hydrocarbons-sub sea oil and gas, minerals from placer deposits to deep sea nodules, sea floor massive sulphides and cobalt rich encrustations.

Noble Gas Geochemistry gives a comprehensive description of the physical chemistry and cosmochemistry of noble gases, before leading on to applications for problem-solving in the earth and planetary sciences. There have been many developments in the use of the noble gases since publication of the first edition of this book in 1983. This second edition has been fully revised and updated. The book will be invaluable to graduate students and researchers in the earth and planetary sciences who use noble gas geochemistry techniques.

Magnesium is one of the most abundant minerals in seawater. Extracting magnesium from seawater could reduce cost of this mineral, resulting in positive implications for industries that use it. This book addresses mineral process engineering with emphasis on magnesium and provides practicing engineers and students with comprehensive knowledge on magnesium and how it is extracted from seawater and magnesium ores. It takes a chemical engineering approach as separation of magnesium from seawater involves the application of the powerful science of chemistry and transport phenomena principles. This monograph discusses magnesium resources and occurrence, includes an exploration study on deriving magnesium and mineral salts from seawater, and features coverage of magnesium chloride. It also covers commercial methods for magnesium production as an end product, current and prospective applications in the energy domain, and offers an account of the use of magnesium to store hydrogen in the form of magnesium hydride.

1. PURPOSE OF PRESENT BOOK During the period May 19-26, 2003 the NATO Advanced Research Workshop (ARW) "Mud volcanism, Geodynamics and Seismicity" was held in Baku. Participants coming from USA, Germany, France, Italy, Portugal, Russian Federation, Ukraine, Romania, Georgia, UK, Israel, Azerbaijan, Tunisia have discussed about different geodynamic features of mud volcanism and participated to field trips oriented to a better knowledge of mud volcanic features. The Meeting focused on many features of mud volcanism occurrence and related geodynamic topics. The purpose of present book is to collect contributions discussed during the Meeting and to fill a marked editorial gap on mud volcanism. Mud volcanism was to date described by local monographies or by articles published by scientific journals. In particular no books were published on topics able to highlight the link among mud volcanism, geodynamics and seismicity. Mud volcano of Nirano (Northern Italy). Engraving from Stoppani A. (1871), Corso di Geologia, Milan, Bernardoni G. and Brigola G. Publishers. 2. WHY MUD VOLCANOES ARE GEOLOGICALLY IMPORTANT ? Mud volcanoes have attracted the attention of earth scientists for many years. Due to their importance in hydrocarbon research, a consistent progress in the knowledge of mud volcanism took place in the past twenty years. Mud extrusion is a well-known phenomenon occurring in geological environments where fluid-rich, fine grained sediments ascend within a lithologic succession due to their buoyancy.

Modern Biogeochemistry is aimed to generalize modern ideas of biogeochemical developments during the last decades. It is designed to support a general course in biogeochemistry, and as such, is likely to have a broad market among the many universities and colleges that are adding such courses to their curricula. This book aims to supplement the existing textbooks by providing modern understanding of biogeochemistry, from evolutionary biogeochemistry to practical applications of biogeochemical ideas such as human biogeochemistry, biogeochemical standards and biogeochemical technologies.
To a certain extent this textbook is a summary of both scientific results of various authors and classes in biogeochemistry, that have been given to students by authors during the last 5 to 10 years at different universities throughout the world such as Cornell, Moscow, Seoul and Bangkok. Biogeochemistry is becoming an increasingly popular subject for graduate and postgraduate education. Courses in ecology, geography, biology, chemistry, environmental science, public health and environmental engineering all tend to have a biogeochemical component in their syllabuses to a greater or lesser extent.

This book is the first systematic treatise of available data and view-points obtained from geological and geochemical studies of the Mo deposits in Qinling Orogen, China. Qinling Orogen has a minimum reserve of 8.7 Mt Mo, ranking the largest molybdenum province both in China and the world. Incorporating all known Mo deposit types in the world, it presents extensive studies of Mo deposits of world-class and unusual types within tectonic settings. The Qinling Orogen was finally formed during continental collision between Yangtze and North China cratons, following the Triassic closure of the northernmost paleo-Tethys. It hosts 49 Mo deposits formed in seven mineralization events since 1850 Ma, with all the world-class deposits being formed during 160-105 Ma, coeval with collisional orogeny. These deposits are assigned to magmatic and metamorphic hydrothermal classes. The magmatic hydrothermal class includes porphyries, skarns, and intrusion-related veins (carbonatite, fluorite and quartz). The porphyry Mo systems in Qinling Orogen are predominated by Dabie-type formed in continental collision setting, followed by Endako- and Climax-types formed in continental arcs and rifts, respectively. The metamorphic hydrothermal Mo deposits are only reported in Qinling Orogen, and thus a new crustal continuum model for the orogenic class mineral systems is proposed. A scientific linkage between ore geology and fluid inclusions is introduced and verified both by theory and case studies. This is the first research book comprehensively displaying continental collision metallogeny. This literature will benefit both Western and Chinese mineral explorers and miners, as well as research scientists and students.

The book presents a new and comprehensive model for the development of phosphate sediments. Starting with geochemistry and including new methods in sedimentology (sequence stratigraphy), it results in an interdisciplinary approach to a resource system covering all fields of phosphate geology. For researchers, teachers and students alike the book offers a complete overview of the whole field including case studies of major deposits.

Held in 1993 in Niterói, Brazil, the first International Conference on Environmental Geochemistry in Tropical Countries established a starting point for this book. The book opens with a discussion of the points that arose during the closing session, summarised by Dr. E.K. Duursma: The Environment in the Tropics Remains Unknown. Most of the processes that occur in temperate environments turn out to be completely different in the tropics. This can already be seen in Chapter 3, where estimates of radionuclide transfer factors reach values considerably greater than in temperate areas. The utilisation of variables measured in temperate environments for modelling of the tropics can result in completely erroneous conclusions and, worse, inefficient remediation solutions.

First published in 1988 this textbook on crystal chemistry covers the basic principles of crystal chemistry and physics and crystallography and introduces the concept of crystal refractivity. The book begins with a discussion of atoms and atomic structure and moves from there to atomic bonding. Throughout this discussion, special emphasis is given to Pauling's rules. The author then treats crystal symmetry, crystal field theory, polyhedral structure and atomic packing. He concludes by introducing the student to more sophisticated optical properties of minerals, refractivity and polarisability in crystals. The material covered is sufficiently basic so that the book will be suitable for undergraduate and graduate student in advanced mineralogy courses. It will also be of interest to individuals, including mineralogists, materials scientists, crystallographers and inorganic chemists who are engaged in academic and industrial research dealing with the structure of the solid state.

This book takes the reader through the complete weathering cycle, from the continents to the oceans, from the perspective of modern radiogenic isotope geochemistry. Topics include surface weathering, fluvial processes, environmental pollution, oceanography and paleoceanography, sedimentary mineral diagenesis and radiometric dating, thus bridging the gap between processes acting on the Earth today and the geological record. Extensive use is made of carefully selected case studies, both pioneering and state-of-the-art. This book enables the reader to critically assess previous work from the literature as well as encouraging already established researchers to apply the most modern isotopic approaches to their particular field of study.

This book focuses on the experimental determination of the physical properties of silicate melts and magmas close to glass transition. Abundant new data are presented. The same type of measurement is performed on a range of melts to test the effect of composition on physical properties; and a range of different techniques are used to determine the same physical properties to illustrate the relationships between the relaxation of the melt structure and the relaxation of its physical properties. This book is of interest to experimental researchers in the discussion of data obtained from both a materials science and a geoscientific point of view.

Understand the Environmental Processes That Control Groundwater Quality The integration of environmental isotopes with geochemical studies is now recognized as a routine approach to solving problems of natural and contaminated groundwater quality. Advanced sampling and analytical methods are readily accessible and affordable, providing abundant geochemical and isotope data for high spatial resolution and high frequency time series. Groundwater Geochemistry and Isotopes provides the theoretical understanding and interpretive methods and contains a useful chapter presenting the basics of sampling and analysis. This text teaches the thermodynamic basis and principal reactions involving the major ions, gases and isotopes during groundwater recharge, weathering and redox evolution. Subsequent chapters apply these principles in hands-on training for dating young groundwaters with tritium and helium and ancient systems with radiocarbon, radiohalides and noble gases, and for tracing reactions of the major contaminants of concern in groundwaters. Covers the basics of solutes, gases and isotopes in water, and concentration-activity relationships and reactions Describes tracing the water cycle, weathering, and the geochemical evolution of water quality Explores dating groundwater as young as a few years to over hundreds of millions of years Uses case studies to demonstrate the application of geochemistry and isotopes for contaminated groundwaters Accessible to consultants and practitioners as well as undergraduates, Groundwater Geochemistry and Isotopes presents the basics of environmental isotopes and geochemistry, and provides you with a full understanding of their use in natural and contaminated groundwater.
