The Working Group M.O. (Interactions of soil minerals with organic components and microorganisms) (WGMO) of the International Soil Science Society (ISSS) was founded in 1990 at the 14th World Congress of Soil Science (Kyoto, Japan), with Professor P.M. Huang being the Chairman. Since then, the Working Group M.O. has served as a forum to bring together soil chemists, soil mineralogists, soil microbiologists, soil biochemists, soil physi cists and environmental, ecological, and health scientists. The objective of the Working Group M.O. is to promote research, teaching, and also the exchange of technology concerning the knowledge and the impact of the interactions between minerals-organics and microorganisms on environmental quality, agricultural sustainability, and ecosystem "health". This group is first a scientific group as defined just previously, but it also intends to develop exchange and transfer between scientists and engineers. The first International Meeting organized by Professor P. M. Huang, was held in Edmonton, Canada, in August 1992, where 87 papers were presented by scientists from 20 countries. Following this meeting, a two volume book was edited by P. M. Huang, J. Berthelin, J.-M. Bollag, W. B. McGill, and A. L. Page, entitled "Environmental impact of soil component interaction" : Volume I "Natural and anthropogenic organic-volume II "Metals, other inorganic and microbial activities", and published by c.R.C. Lewis Pub lishers (1995).

A significant advance in climatological scholarship, Tectonic Uplift and Climate Change is a multidisciplinary effort to summarize the current status of a new theory steadily gaining acceptance in geoscience circles: that long-term cooling and glaciation are controlled by plateau and mountain uplift. Researchers in many diverse fields, from geology to paleobotany, present data that substantiate this hypothesis. The volume covers most of the key, dramatic transformations of the Earth's surface.

The research papers in this book present current knowledge of the sources, pathways, behavior, and effects of trace elements in soils, waters, plants, and animals. It is of interest to a variety of readers, including public health and environmental professionals, consultants, and academicians.

John E. Mylroie and Ira D. Sasowsky' Caves occupy incongruous positions in both our culture and our science. The oldest records of modem human culture are the vivid cave paintings from southern France and northern Spain, which are in some cases more than 30,000 years old (Chauvet, et ai, 1996). Yet, to call someone a "caveman" is to declare them primitive and ignorant. Caves, being cryptic and mysterious, occupied important roles in many cultures. For example, Greece, a country with abundant karst, had the oracle at Delphi and Hades the god of death working from caves. People are both drawn to and mortified by caves. Written records ofcave exploration exist from as early as 852 BC (Shaw, 1992). In the decade of the 1920's, which was rich in news events, the second biggest story (as measured by column inches of newsprint) was the entrapment of Floyd Collins in Sand Cave, Kentucky, USA. This was surpassed only by Lindbergh's flight across the Atlantic (Murray and Brucker, 1979).

This revised edition of the text provides coverage of the entire field of geochemistry, including a basic review of the fundamental physico-chemical principles of solid, liquid, and gaseous states of matter. It includes an in-depth discussion of the geochemistry of the solid state and trace element geochemistry. It also discusses interionic static potentials in crystals, thermodynamic properties based on lattice vibrations, and crystalline defects and their effect on stability relations of minerals.;Other chapters cover elemental properties and crystal chemistry; the thermochemistry of silicate melts; an introduction to petrogenetic systems; and the geochemistry of aqueous and gaseous phases. A new chapter provides an introduction to the principles of isotope geochemistry.

Volume 16 of Advances in Microbial Ecology has a difficult history. Nearly halfway through its completion, Gwynfryn Jones had to resign as managing edi tor for health reasons, and he asked me to take over. I want to thank Gwyn for his dedicated work in this publication series, and wish him all the best for the future. After the change in editorship, some authors had to be encouraged on rather short notice to provide their chapters in order to make appearance of this volume possible within a reasonable period of time. Nonetheless, I think that the articles we present with this volume represent an enjoyable collection of up-to-date con tributions to microbial ecology. In my own understanding, microbial ecology com prises the elucidation of microbial activities in natural or semi natural environ ments, including physiology, biochemistry, population dynamics, and interactions with all the biotic and abiotic environmental conditions microbes encounter. This comprises studies on single organisms in defined cultures in an ecological per spective, the analysis of microbial activities in complex environments, as well as the development of concepts for the interactions of microorganisms with the world in which they live. Last but not least, microbial ecology is not an exotic science studied exclusively in remote places untouched by human beings."

In its classical sense "epigenesis" refers to all geological processes originating at or near the surface of the earth. It thus embraces all those phenomena which we associate with the land scape; Perel'man has already written extensively on this subject. The landscape, in the physical sense, is controlled by the interac tion of exogenic and endogenic agencies-on the one hand, the atmo sphere, the wind, the rain, and other components of the weather, the forces of running water and the planetary controls of gravitational and tidal nature; and on the other hand the materials of the earth's crust, from sediments to metamorphic rocks and igneous materials from deep endogenic sources. In practical terms the epigene region involves the products of weathering, the soils, the transported material, the colluvium of hillsides, and the alluvium of stream valleys. It involves those landforms that are products of the erosional sculpturing of the landscape, as well as those that result from accumulation, such as glacial moraines and desert sand dunes. The science of geomor phology is gradually beginning to evolve from a passive cataloging of scenery and its deduced causes (in the Davisian sense) into a vigorous study of dynamic processes. These are partly geophysical, in the sense of hydraulics and mechanical studies, and partly geo chemical."

The problem of the geochemical migration of elements has received wide attention in the works of V. I. Vernadskii and A. E. Fersman [1, 2J. Vernadskii considered geochemistry to be the science of the history of chemical elements on the earth, their distribution and move ments in space and time, and their genetic relations [IJ. Geochemical migration was defined by Fersman as "the movement of chemical elements in the earth's crust leading to their dissemination or concentration. " The views of Vernadskii and Fersman on the migration of elements have received added support and development in connection with successes in physics, chemistry, biology, and other sciences. According to Fersman, the earth is looked upon as a cosmic body, characterized by common origin and Similarity of composition with the sun, the planets, meteorites, and other bodies of the solar system. The scale and trend of geochemical migration of elements in the earth are determined by the initial state of terrestrial matter, its thermal history, and the scale of time. The rules of elemental migration are determined by internal and exterual fac tors. Fersman distinguishes five groups of internal factors, i. e.

This is a book about the why and how of doing experiments on rocks, minerals, magmas, and fluids. It could have as logically been subtitled "Experimental petrology" as "Experimental geochemistry," but we chose geochemistry to emphasize the broad and overlapping nature of current experimental work. We have tried to aim the book at a general readership which we hope will include advanced undergraduate students, graduate students, and anyone else interested in learning something about experimental petrology. Although we hope there will be something of interest for the practicing experimentalist, our aim is at the non-experimentalist interested in learning why experiments are useful, what kind of experiments can be done, and what some of the major problems and limitations are and how they can best be avoided. The result of a journey through this book should be an ability to evaluate published experimental work critically and a knowledge of the kinds of problems an experimentalist might be able to help solve. Some details of experimental technique are included in the Appendix for those readers who want to "get their hands dirty. " Indeed, one of our main incentives for writing this book was to try to encourage more petrologists and geochemists to become experimentalists. In our pedagogical approach we have chosen to discuss a small number of case histories as illustrations of principles and techniques. We have tried to select studies we regard as well executed.

How large is the natural variation in concentration of the various elements in different media? How do the oft-cited "World average concentrations" in different media compare with actual analytical data? How low a detection limit do I need to attain if I want to analyse for an element in soils, sediments, water or plants? All these questions and many more can be answered by using this unique reference book. It collates data on the most important properties and uses of all naturally occurring chemical elements. It combines these with data obtained from actual analyses of different sample media (soil, stream sediment, stream water, ground water, plants, human body fluids). This combination of facts and actual data makes this book suitable for learning and teaching applied geochemistry as well.

Hydraulic parameter identification is a crucial step in hydrogeological investigations. The book proposes a unique and generalized interpretation method for single and multiple pumping tests made in groundwater reservoirs with layered heterogeneity and with or without lateral anisotropy. This method eliminates the drawbacks of the numerous and frequently applied interpretation methods. The book also presents an introduction to inverse modeling, resulting in optimal parameter values with their joint confidence region and the corresponding residuals. Cross sections through this multidimensional region elucidate the relation between the shape of this region and some statistical parameters describing the reliability of the identified parameters. This method is demonstrated by means of five pumping or recharge tests.

The Bear Brook Watershed in Maine (BBWM) is a long-term, whole-watershed study examining the effects of experimentally elevated N and S deposition on a treated watershed, in comparison to the adjacent reference watershed. The study is in a northern New England, USA, forested ecosystem, and focuses on soil and stream hydrological and biogeochemical processes, and chemical responses of vegetation. Relative to the reference watershed, the treated ecosystem has migrated biogeochemically towards N saturation, and soil and stream acidification. Some of the responses to N amendments were not expected nor predicted by available models.

This book deals with the processes behind cycles of the phosphate and nitrogen compounds in sediment and the phosphate equilibria between the sediment and the overlying water. In most waters, excessive concentrations of these compounds causes eutrophication: rapid, choking growth of algae. The chapters of this book probe the chemicals involved in considerable detail, and offer the complete understanding needed to remediate or prevent pollution problems.

This newly revised edition of "Global Environment" discusses the major elements of the geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and oceans, as well as the human effects on these fluxes. Retaining the strengths of the original edition while incorporating the latest discoveries, this textbook takes an integrated, multidisciplinary, and global approach to geochemistry and environmental problems and introduces fundamental concepts of meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography.

New concepts and information in this updated edition include changes of atmospheric carbon dioxide over geologic time, major advances in the study of chemical weathering of rocks, ocean acidification, and important environmental problems, such as the amelioration of the acid rain problem due to reduction in sulfur deposition, problems with nitrification of soils and lakes, and eutrophication of rivers and estuaries. An expanded chapter explores atmospheric chemistry and changing climate, with the most up-to-date statistics on CO2, the carbon cycle, other greenhouse gases, and the ozone hole. Only requiring a fundamental understanding in elementary chemistry, yet taking into account extensive and current data, this text is ideal for students in environmental geochemistry, environmental geology, global change, biogeochemistry, water pollution, geochemical cycles, chemical oceanography, and geohydrology, and serves as a valuable reference for researchers working on global geochemical and environmental issues.Revised edition takes a close look at global fluxes involving the atmosphere, land, lakes, rivers, biota, and oceans, and the human effects on these fluxes Detailed discussion of basic concepts including meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography An expanded up-to-date chapter on atmospheric chemistry and changing climate, including CO2, other greenhouse gases, and ozone Presentation of major advances in the study of chemical weathering Discussion of current environmental topics Global coverage of environmental problems involving water

An isotope is a variant form of a chemical element, containing a different number of neutrons in its nucleus. Most elements exist as several isotopes. Many are stable while others are radioactive, and some may only exist fleetingly before decaying into other elements. In this Very Short Introduction, Rob Ellam explains how isotopes have proved enormously important across all the sciences and in archaeology. Radioactive isotopes may be familiar from their use in nuclear weapons, nuclear power, and in medicine, as well as in carbon dating. They have been central to establishing the age of the Earth and the origins of the solar system. Combining previous and new research, Ellam provides an overview of the nature of stable and radioactive isotopes, and considers their wide range of modern applications. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Written 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"

All Earth Science students need to understand the origins, environments, and basic processes that produce igneous and metamorphic rocks. This concise introductory textbook provides students with the essential knowledge needed to understand how petrology relates to other topics in the geologic sciences, and has been written specifically for one-semester courses. Throughout, the emphasis is on interpreting the mineralogy and petrology of rock suites in terms of origin and environment, with the first half of the book concentrating on igneous rocks, and the second half on metamorphic rocks. This Second Edition has been thoroughly revised and brought completely up-to-date. It now includes a new chapter on the application of stable and radiogenic isotopes in petrology, introducing students to the concept of isotopic fractionation and describing the process of radioactive decay. The discussions of phase diagrams, connections between igneous and metamorphic rock suites, and convergent margin magmatism have also been expanded. There is a new glossary of terms, updated end-of-chapter exercises, and updated further readings.

Features 135 splendid color photographs, ranges from vast rock-landscapes recorded in Europe, America, Australia, and Iceland right down to finely detailed images of a few square millimeters. Close-ups of crystals, gems, and fossils are alternated with micro-images of the minute textures and patterns that emerge from thin, translucent sections of rocks and minerals. Literally, as well as figuratively Dirk Wiersma, the photographer, zooms in` on the subject matter, leading the reader deeper into various spaces of surprising new forms and perspectives, at times abstract, at other times (pseudo)realistic. Brief accompanying texts are written in a style that is accessible and appealing to a general audience, while also providing the necessary factual information.

Ocean Hotspots provides a comprehensive overview of recent and ongoing research on intraplate volcanism in the ocean basins with special emphasis on the Pacific Ocean. The geology of the seamounts and their associated seamount chains is described, along with detailed geophysical, geochemical and hydrothermal observations made by a multi-disciplinary group of marine geoscientists. These observations lead to a deeper understanding of how the ascending mantle melts, represented by hotspots, are able to penetrate the lithosphere, build seamounts, and enhance hydrothermal circulation. The "fixed" hotspot-generated seamount chains also provide key constraints on plate tectonic reconstructions on the Earth's crust.

"Marine Geochemistry" offers a fully comprehensive and integrated treatment of the chemistry of the oceans, their sediments and biota. The first edition of the book received strong critical acclaim and was described as '"a standard text for years to come."' This third edition of "Marine Geochemistry" has been written at a time when the role of the oceans in the Earth System is becoming increasingly apparent.

Following the successful format adopted previously, this new edition treats the oceans as a unified entity, and addresses the question '"how do the oceans work as a chemical system?"' To address this question, the text has been updated to cover recent advances in our understanding of topics such as the carbon chemistry of the oceans, nutrient cycling and its effect on marine chemistry, the acidification of sea water, and the role of the oceans in climate change. In addition, the importance of shelf seas in oceanic cycles has been re-evaluated in the light of new research.

"Marine Geochemistry" offers both undergraduate and graduate students and research workers an integrated approach to one of the most important reservoirs in the Earth System.Additional resources for this book can be found at: www.wiley.com/go/chester/marinegeochemistry.

This book introduces the general principles of reaction equilibria and kinetics involved in marine geochemical cycles. The major electrolytes dramatically affect the rates and equilibria of the chemical reactions in the sea. In order to understand these interactions, it is necessary to have a detailed knowledge of the major, minor and trace chemical components. This volume is also focused on the development and applications of analytical techniques for accurate determination and speciation in seawater, and on the effect of pollution on the marine environment, since small quantities of other elements may have a significant influence on global chemical cycling. Audience: This book is of value for marine chemists, biogeochemists, ecologists, oceanographers, environmental engineers and analytical chemists.

Riverbank filtration is a low cost, yet efficient water treatment technology. It has most potential to provide safe drinking water to large cities located along rivers or lakes. In particular, it is ideal for large population centres in developing countries, where the cost of building extensive treatment facilities is prohibitive. Water filtration can be successfully implemented using naturally occurring sand and gravel along the river/lake banks. The cost of water produced by this means is much lower than that of water treated in conventional treatment plants. Authored by a multi-disciplinary team of experts, this volume addresses the scientific basis of the filtration process, and also numerous topics of importance for the planning, technical realization, and security of such plants. Their application for the removal of relevant chemical pollutants and a variety of pathogens is analysed in detail.

An ever-increasing concern over environmental degradation, together with recent technological advances, has spawned an explosion of chemical data for a wide variety of matter found on earth and in the solar system. Yuan-Hui Li's book offers professionals and students alike an indispensable up-to-date guide to geochemistry, bringing together new information on topics ranging from nucleosynthesis to crystal chemistry, from the systematics of chemical variation in the earth's core to the composition of complex organics. The objective is to illustrate the physicochemical principles and various natural processes that can explain observed compositional changes in natural substances. A general understanding of these principles and processes (including those pertaining to cosmology, geology, and biology) is essential, maintains the author, for deciphering and predicting transport pathways and final sinks of anthropogenic pollutants in our environment.

The book focuses on compositional data and related references for such substances as solar photosphere, meteorites, igneous rocks, soils, sedimentary rocks, surficial waters, marine and terrestrial organisms (including humans), and aerosols. It emphasizes the use of original raw data as much as possible, and applies the statistical technique of factor analysis to elucidate any underlying interrelationships among chemical elements and given sample sets. Whenever applicable, simple chemical thermodynamic models are introduced to explain the observed partitioning of elements among different phases.
