This book discusses the application of geochemical models to environmental practice and studies, through the use of numerous case studies of real-world environmental problems, such as acid mine drainage, pit lake chemistry, nuclear waste disposal, and landfill leachates. In each example the authors clearly define the environmental threat in question; explain how geochemical modeling may help solve the problem posed; and advise the reader how to prepare input files for geochemical modeling codes and interpret the results in terms of meeting regulatory requirements.

A link between iron bioavailability and phytoplankton growth in the oceans was first put forward in the 1930s but it was not until the 1980s that developments in clean sampling and analytical techniques had advanced sufficiently to allow accurate measurements of iron at trace levels. The 1990s have been dubbed the 'Iron Age of Oceanography', and there is no doubt that the role played by iron in plankton ecology has been the decade's 'hot topic' in marine biogeochemistry. During that time the field has developed rapidly, and the initial simple hypothesis, that shortage of iron limits primary production in large areas of the ocean, has evolved into a new paradigm which recognises that iron, along with nitrogen, phosphorus and silicon, is an essential plant nutrient whose availability is a key determinant of phytoplankton growth and species distribution.

The Biogeochemistry of Iron in Seawater will be an invaluable reference for academics and graduate students in marine sciences as well as marine scientists and oceanographers; environmental analytical chemists; and scientists studying the environmental impact of metals and their role in marine ecosystems.

This book is a comprehensive treatment of fine particle magnetism and the magnetic properties of rocks. Starting from atomic magnetism and magnetostatic principles, the authors explain why domains and micromagnetic structures form in ferrimagnetic crystals and how these lead to magnetic memory in the form of thermal, chemical and other remanent magnetizations. One chapter is devoted to practical tests of domain state and paleomagnetic stability. Another deals with pseudo-single-domain magnetism, i.e., particles that contain domain walls but behave like a single domain. The final four chapters place magnetism in the context of igneous, sedimentary, metamorphic, and extraterrestrial rocks. This book will appeal to researchers in the earth sciences, physics, and engineering.

As in the original edition of 1988, this book covers the principles and practice of argon isotopic dating, a technique that has been used to determine the numerical age of the Earth. The greater precision of the 40Ar/39Ar method allows scientists to test smaller geological samples than its precursor, the K-Ar method, which required a comparison of different elements. The new edition will incorporate new developments made in 40Ar/39Ar application over the last decade, made possible by advances in lasers and mass spectrometry.

The book is a quantitative treatment of the theory and natural variations of light stable isotopes, and includes more than 100 original applications. Isotope distribution is rigorously discussed in the context of fractionation processes, thermodynamics, mass conservation, exchange kinetics and diffusion theory. The theoretical principles are illustrated with natural examples, emphasizing oygen and hydrogen isotope variations in natural waters, terrestrial and extraterrestrial rocks, and hydrothermal systems. New data on meteoric precipitation, rivers, and hydrothermal systems are included.

Topics covered: Geochemical record of terrestrial environmental change, and global geochemical cycles; Chemical weathering and climate, river catchment studies; Environmental geochemistry of the terrestrial environment and its effect on health; Organic geochemistry; Marine and sedimentary geochemistry; Mineralogy, microbes and chemistry of weathering; Geochemical thermodynamics and kinetics; Geochemistry of crustal fluids and of catastrophic events.

Geochemical reaction modeling plays an increasingly vital role in several areas of geoscience ranging from groundwater and surface water hydrology to environmental preservation and remediation to economic and petroleum geology. This book provides an up-to-date overview and a large number of fully worked examples of the use of numerical methods to model reaction processes in the Earth's crust and on its surface. Special attention is given to integrating surface complexation, kinetic rate laws, and isotope fractionation into quantitative process models. Earth science professionals and students in a variety of specialties will benefit from the wealth of information and practical advice this book has to offer.

Modern geochemistry aims to provide an accurate description of geological processes, and a set of models and quantitative rules that help predict the evolution of geological systems. This work is an introduction to the mathematical methods of geochemical modeling, largely based on examples presented with full solutions. It shows how geochemical problems, dealing with mass balance, equilibrium, fractionation and dynamics and transport in the igneous, sedimentary and oceanic environments, can be reformulated in terms of equations. Its practical approach then leads to simple but efficient methods of solution. This book should help the motivated reader to overcome the formal difficulties of geochemical modeling, and bring state-of-the-art methods within reach of advanced students in geochemistry and geophysics, as well as in physics and chemistry.

This work combines research results with review papers, discussing dykes from different scientific perspectives. Coverage includes: current dyke geometry measurements; field observation of host rock deformation; textural analyses; and geochemical and petrological studies of dyke swarms.

This reference provides up-to-date information on research in many different disciplines which give an overall insight into the environmental history of Africa.

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.

The congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for arsenic research aimed at practical solutions of problems with considerable social impact, as well as focusing on cutting edge and breakthrough research in physical, chemical, toxicological, medical and other specific issues on arsenic on a broader environmental realm. The congress "Arsenic in the Environment" was first organized in Mexico City (As 2006) followed by As 2008 in Valencia, Spain and As 2010 in Tainan, Taiwan. The 4th International Congress As 2012 was held in Cairns, Australia from July 22-27, 2012 entitled Understanding the Geological and Medical Interface of Arsenic. The session topics comprised: 1. Geology and hydrogeology of arsenic; 2. Medical and health issues of arsenic; 3. Remediation and policy; 4. Analytical methods for arsenic; and 5. Special topics on "Risk assessment of arsenic from mining", "Geomicrobiology of arsenic", "Geothermal arsenic", "Rice arsenic and health perspectives", "Sustainable mitigation of arsenic: from field trials to policy implications", and "Biogeochemical processes of high arsenic groundwater in inland basins" Hosting this congress in Australia was welcome and valued by the local scientific communities. Australia is a mineral rich country where mining has generated significant economic benefit to its people. Unfortunately historical mining for base metals, gold and arsenic had led to environmental contamination of arsenic. Locally produced arsenical compounds were widely used as pesticides and in timber preservation. It is known that there are several thousands of cattle- and sheep-dip sites contaminated with arsenic in Australia. However, commonly observed symptoms of chronic arsenic poisonings such as those found in endemic-blackfoot areas are seemingly absent from these types of environmental contamination due to good quality of potable water supply. Does this fall in the classic argument of "the dose makes the poison"? This congress theme of "understanding the geological and medical interface of arsenic" will advance our knowledge in minimising the risk posted by this so-called number one prioritised contaminant - arsenic.

The term "carbon cycle" is normally thought to mean those processes that govern the present-day transfer of carbon between life, the atmosphere, and the oceans. This book describes another carbon cycle, one which operates over millions of years and involves the transfer of carbon between rocks and the combination of life, the atmosphere, and the oceans. The weathering of silicate and carbonate rocks and ancient sedimentary organic matter (including recent, large-scale human-induced burning of fossil fuels), the burial of organic matter and carbonate minerals in sediments, and volcanic degassing of carbon dioxide contribute to this cycle. In The Phanerozoic Carbon Cycle, Robert Berner shows how carbon cycle models can be used to calculate levels of atmospheric CO 2 and O 2 over Phanerozoic time, the past 550 million years, and how results compare with independent methods. His analysis has implications for such disparate subjects as the evolution of land plants, the presence of giant ancient insects, the role of tectonics in paleoclimate, and the current debate over global warming and greenhouse gases

Granites are emblematic rocks developed from a magma that crystallized in the Earth's crust. They ultimately outcrop at the surface of every continent. This book - translated, edited, and updated from the original French edition Petrologie des Granites published by Vuibert in 2011 - gives a modern presentation of granitic rocks, or granites, from magma genesis to their emplacement into the crust and their crystallization. Mineralogical, petrological, physical, and economical aspects are developed in a succession of 14 chapters. Special 'info boxes' discuss topics for those wishing to deepen their knowledge of the subject. Also included is a glossary, a comprehensive bibliography, as well as descriptions of modern techniques. Granites are considered in their geological spatial and temporal frame, in relation with Plate Tectonics and Earth History, and assisted by a large number of high quality illustrations.

Fission track dating is based on the microscopic observation and counting of etchable tracks left by the spontaneous fission of uranium in minerals. Since its development in 1963 the method attracted a steadily growing interest from geologists and geochronologists throughout the world. Apart from its relative experimental ease the success must be mainly ascribed to the specific ability of the method of unravelling the thermal and tectonic history of rocks, a potential which only became fully exploited during the last decade with the systematic introduction of track size analysis. This work deals with fission track dating covering all of its aspects from the origin of the fission tracks, the basis of track etching and fading, the various dating techniques as well as practical procedures and the geologic interpretation to recent applications in geology and archaeology.

Water-Rock Interaction presents new research on the chemical interaction of aqueous fluids with the rock matrix containing them. The contributions come from a wide variety of geologic settings and include groundwater-aquifer reactions, hydrothermal fluids in volcanic and ore deposit environments and water-rock interaction in geothermal areas. The focus is on upper crustal and near surface environments. The presented research comprises field studies as well as experimental work. The book adds new data and understanding to the multifaceted general process of chemical interaction of water and rock.
Audience: The book will appeal to hydrologists and hydrogeologists interested in chemical aspects of water, but solid earth geophysicists, geochemists and petrologists with an interest in fluids in the crust will also find new stimulating ideas in this volume.

This textbook presents a comprehensive process-oriented approach to biogeochemistry that is intended to appeal to readers who want to go beyond a general exposure to topics in biogeochemistry, and instead are seeking a holistic understanding of the interplay of biotic and environmental drivers in the cycling of elements in forested watersheds. The book is organized around a core set of ecosystem processes and attributes that collectively help to generate the whole-system structure and function of a terrestrial ecosystem. In the first nine chapters, a conceptual framework is developed based on distinct soil, microbial, plant, atmospheric, hydrologic, and geochemical processes that are integrated in the element cycling behavior of watershed ecosystems. With that conceptual foundation in place, students then proceed to the final three chapters where they are challenged to think critically about integrated element cycling patterns; roles for biogeochemical models; the likely impacts of disturbance, stress, and management on watershed biogeochemistry; and linkages among patterns and processes in watersheds experiencing novel environmental changes. Included with the text are figures, tables of comparative data, extensive literature citations, a glossary of terms, an index, and a set of 24 biogeochemical problems with answers. The problems are intended to support chapter concepts and to demonstrate how critical thinking skills, simple algebra, and thoughtful human logic can be used to solve applied problems in biogeochemistry that might be encountered by a research scientist or a resource manager. Using this book as an introduction to biogeochemistry, students will achieve a level of subject mastery and disciplinary perspective that will permit them to see and to interpret the individual components, interactions, and synergies that are represented in the dynamic element cycling patterns of watershed ecosystems.

Biomining uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates. This book takes a strong applied approach to the study of biomining. It describes emerging and established industrial processes, as well as the underlying theory of the process, along with the biology of the microorganisms involved. Chapters have been contributed by experts from leading biomining companies, consultants and internationally recognized researchers and academics.

The basis of this investigation is the petrographic and geochemical understanding of principal igneous rock types of the Noril sk region, in order to demonstrate that these data provide unique and self-evident solutions to the problems of petrogenesis and mineralization. The results of the investigations are presented in two volumes: the first includes mainly text and the second contains illustrations.
In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. Taking into account the vast number of publications on the petrology of Traps of the Noril sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. Some exotic geologic targets such as the Mikchandinsky differentiated cover, the magnetite lava flow of the Putorana Plateau, the magmatogenic breccia of Kharaelakh and others are described in detail.
The second volume contains an atlas of Rock Indications of igneous rock-types; formally identified reference rocks from all igneous complexes of the region, as well as photographs of thin sections of typical rocks and analytical tables of rocks and minerals from the key sections of sedimentary units and intrusions. Each rock type has been geochemically and petrographically analysed thereby providing a formal identity, complete with a photograph of the thin section. Photomicrographs of the rocks in this book will be a useful aid in visualizing the diversity of rock types in the Traps; each photograph reflecting a unique combination of minerals."

The molecular mechanisms underlying the fact that a crystal can take a variety of external forms is something we have come to understand only in the last few decades. This is due to recent developments in theoretical and experimental investigations of crystal growth mechanisms.
Morphology of Crystals is divided into three separately available volumes. Part A contains chapters on roughening transition; equilibrium form; step pattern theory; modern PBC; and surface microtopography. This part provides essentially theoretical treatments of the problem, particularly the solid-liquid interface. Part B contains chapters on ultra-fine particles; minerals; transition from polyhedral to dendrite; theory of dendrite; and snow crystals. All chapters are written by world leaders in their respective areas, and some can be seen as representing the essence of a life's work. This is the first English-language work which covers all aspects of the morphology of crystals - a topic which has attracted top scientific minds for centuries. As such, it is indispensable for anyone seeking an answer to a question relating to this fascinating problem: mineralogists, petrologists, crystallographers, materials scientists, workers in solid-state physics and chemistry, etc.
In Parts A: Fundamentals and B: Fine Particles, Minerals and Snow equilibrium and kinetic properties of crystals are generally approached from an atomistic' point of view. In contrast, Part C: The Geometry of Crystal Growth follows the alternative and complementary geometrical' description, where bulk phases are considered as continuous media and their interfaces as mathematical surfaces with orientation-dependent properties. Equations of motion for a crystal surface are expressed in terms of vector and tensor operators working on surface free energy and growth rate, both expressed as functions of surface orientation and driving force, or affinity' for growth. This approach emphasizes the interrelation between equilibrium and kinetic behavior. Part 1 establishes the theoretical framework. Part 2 gives a construction toolbox for explicit (analytic) functions. An extra chapter is devoted to experimental techniques for measuring such functions: a new approach to sphere growth experiments. The emphasis throughout is on principles and new concepts.
Audience: Advanced readers familiar with traditional aspects of crystal growth theory. Can be used as the basis for an advanced course, provided supplementation is provided in the areas of atomistic models of the advancing surface, diffusion fields, etc.

This second volume in the series 'Fundamentals in Organic Geochemistry' focusses on molecular chemical aspects introducing the structural diversity of natural products, their fate in the sedimentary systems and the consequences of the corresponding alterations for geoscientific questions. Organic Geochemistry is a modern scientific subject characterized by a high transdisciplinarity and located at the edge of chemistry, environmental sciences, geology and biology. Therefore, there is a need for a flexible offer of appropriate academic teaching material on an undergraduated level addressed to the variety of students coming originally from different study disciplines. For such a flexible usage this textbook series consists of different volumes with clear defined aspects and with manageable length.
