Geochemistry

A Comprehensive Introduction to the “Geochemist Toolbox” – the Basic Principles of Modern Geochemistry In the new edition of William M. White’s Geochemistry, undergraduate and graduate students will find each of the core principles of geochemistry covered. From defining key principles and methods to examining Earth’s core composition and exploring organic chemistry and fossil fuels, this definitive edition encompasses all the information needed for a solid foundation in the earth sciences for beginners and beyond. For researchers and applied scientists, this book will act as a useful reference on fundamental theories of geochemistry, applications, and environmental sciences. The new edition includes new chapters on the geochemistry of the Earth’s surface (the “critical zone”), marine geochemistry, and applied geochemistry as it relates to environmental applications and geochemical exploration. ● A review of the fundamentals of geochemical thermodynamics and kinetics, trace element and organic geochemistry ● An introduction to radiogenic and stable isotope geochemistry and applications such as geologic time, ancient climates, and diets of prehistoric people ● Formation of the Earth and composition and origins of the core, the mantle, and the crust ● New chapters that cover soils and streams, the oceans, and geochemistry applied to the environment and mineral exploration In this foundational look at geochemistry, new learners and professionals will find the answer to the essential principles and techniques of the science behind the Earth and its environs.

Applied Geochemistry: Advances in Mineral Exploration Techniques is a book targeting all levels of exploration geologists, geology students and geoscientists working in the mining industry. This reference book covers mineral exploration techniques from multiple dimensions, including the application of statistics - both principal component analysis and factor analysis - to multifractal modeling. The book explains these approaches step-by-step and gives their limitations. In addition to techniques and applications in mineral exploration, Applied Geochemistry describes mineral deposits and the theories underpinning their formation through worldwide case studies. Includes both conventional and nonconventional techniques for mineral exploration, including lithogeochemical methods Highlights the importance and applications of multifractal models, 3D - mineral prospectivity modeling Features case studies from mines and mineral exploration ventures around the world

From measuring geological time, through unravelling the evolution of continents, ocean and mantle, to understanding climate change, modern geochemistry is a discipline which pervades nearly all of the Earth Sciences. Geochemistry provides a broad introduction to the subject, which concentrates on the inorganic chemistry of the condensed part of our planet. This new textbook is written by the author of the authoritative and widely acclaimed Introduction to Geochemical Modelling (Cambridge, 1995). Emphasizing general principles rather than specific observations, Professor Albarède leads the reader through the simplest concepts of physics and chemistry behind geochemical processes. He covers fields central to geochemistry, such as crystal chemistry, mass balance and element transport, and geochemical dynamics. A broad range of applications is introduced, in natural water systems, the deep Earth and planetary processes. Geochemistry is an ideal textbook for undergraduate students, and will also provide an accessible introduction for researchers working in related fields.

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 Albarède'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.

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

Updated throughout with the latest data and findings, the Second Edition of Essentials of Geochemistry provides students with a solid understanding of the fundamentals of and approaches to modern geochemical analysis. The text uses a concepts of chemical equilibrium approach, which considers the reactions that occur as a result of changes in heat production and pressure within the Earth to introduce students to the basic geochemical principles. This text is for those who want a quantitative treatment that integrates the principles of thermodynamics, solution chemistry, and kinetics into the study of earth processes. This timely text contains numerous examples and problems sets which use SUPCRT92 to allow students to test their understanding of thermodynamic theory and maximize their comprehension of this prominent field. New sections introduce current “hot” topics such as global geochemical change with the short and long term carbon cycle, carbon isotopes and the Permo-Triassic extinction event, kinetics and the origin of life and the use of boron and nitrogen isotopes.

This book is intended to serve as a text for an introductory course in geochemistry for undergraduate/graduate students with at least an elementary–level background in earth sciences, chemistry, and mathematics. The text, containing 83 tables and 181 figures, covers a wide variety of topics — ranging from atomic structure to chemical and isotopic equilibria to modern biogeochemical cycles — which are divided into four interrelated parts: Crystal Chemistry; Chemical Reactions (and biochemical reactions involving bacteria); Isotope Geochemistry (radiogenic and stable isotopes); and The Earth Supersystem, which includes discussions pertinent to the evolution of the solid Earth, the atmosphere, and the hydrosphere. In keeping with the modern trend in the field of geochemistry, the book emphasizes computational techniques by developing appropriate mathematical relations, solving a variety of problems to illustrate application of the mathematical relations, and leaving a set of questions at the end of each chapter to be solved by students. However, so as not to interrupt the flow of the text, involved chemical concepts and mathematical derivations are separated in the form of boxes. Supplementary materials are packaged into ten appendixes that include a standard–state (298.15 K, 1 bar) thermodynamic data table and a listing of answers to selected chapter–end questions.
