Colloid science has been applied by soil chemists and clay mineral ogists for many years, and some of the most important studies on the behavior of colloids have been contributed by them. Barring a few notable exceptions, only in the last decade have geochemists applied colloid science in their research and in this period much work has been published. It seemed to the authors that it would be useful at this stage to attempt to summarize the progress made and to try to examine what colloid science has contributed and can further contribute to geo chemistry. This book is based partly on a course of the same title given to graduate students by one of the authors (S. Y) between 1972 and 1977 at the Department of Geology at the Hebrew University of Jerusalem. Consequently many fundamental concepts of the subject are included that will be of use to graduate students in geology, geo chemistry, soil science, and oceanography. So that specialists interested in certain sections may find their subjects comprehensively covered, a few topics are dealt with in more than one chapter so that readers may ignore sections not especially of interest to them. However the chapters more fully treating certain topics are cross-referenced. In such cases the subjects are treated from different viewpoints and the citations used represent these dif fering viewpoints.

The first edition of this book demystified the process of well log analysis for students, researchers and practitioners. In the two decades since, the industry has changed enormously: technical staffs are smaller, and hydrocarbons are harder to locate, quantify, and produce. New drilling techniques have engendered new measurement devices incorporated into the drilling string. Corporate restructuring and the "graying" of the workforce have caused a scarcity in technical competence involved in the search and exploitation of petroleum. The updated 2nd Edition reviews logging measurement technology developed in the last twenty years, and expands the petrophysical applications of the measurements.

This is a complete and authoritative reference text on an evolving field. Over 200 international scientists have written over 340 separate topics on different aspects of geochemistry including organics, trace elements, isotopes, high and low temperature geochemistry, and ore deposits, to name just a few.

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.

Diagenesis is a highly developed, interdisciplinary field of study. It is reciprocal in that it borrows from numerous scientific or technological specialities and then, in turn, repays them with useful results. Too often, however, the information gained and concepts developed remain unintegrated instead of being utilized quickly by several related earth-science fraternities. This volume, the first of a multi-volume work, attempts to bring together such information, thereby assisting the individual and the research group in keeping up with the data explosion.There is no end in sight to diagenetic research because of its wide practical and intellectual appeals. Consequently, periodic reviews, such as presented in this volume, are greatly needed.

Geochemistry of Earth Surface Systems offers an interdisciplinary reference for scientists, researchers and upper undergraduate and graduate level geochemistry students a sampling of articles on earth surface processes from The Treatise on Geochemistry that is more affordable than the full Treatise. For professionals, this volume will provide an overview of the field as a whole. For students, it will provide more in-depth introductory content than is found in broad-based geochemistry textbooks. Articles were selected from chapters across all volumes of the full Treatise, and include: Volcanic Degassing, Hydrothermal Processes, The Contemporary Carbon Cycle, Global Occurrence of Major Elements in Rivers, Organic Matter in the Contemporary Ocean, The Biological Pump, and Evolution of Sedimentary Rocks. Comprehensive, interdisciplinary and authoritative content selected by leading subject experts Robust illustrations, figures and tables Affordably priced sampling of content from the full Treatise on Geochemistry

Deze derde herziene uitgave op het gebied van de chemische karakteristieken van natuurlijk water (grond- en oppervlaktewater) is uitgegaan van hetzelfde basis-organisatiemodel en dient dezelfde algemene doelstellingen als voorgaande uitgaven
