This book provides a comprehensive introduction to the field of geochemistry The book first lays out the geochemical toolbox the basic principles & techniques of modern geochemistry beginning with a review of thermodynamics & kinetics as they apply to the Earth & its environs These basic concepts are then applied to understanding processes in aqueous systems & the behavior of trace elements in magmatic systems Subsequent chapters introduce radiogenic & stable isotope geochemistry & illustrate their application to such diverse topics as determining geologic time ancient climates & the diets of prehistoric peoples The focus then broadens to the formation of the solar system the Earth & the elements themselves Then the composition of the Earth itself becomes the topic examining the composition of the core the mantle & the crust & exploring how this structure originated A final chapter covers organic chemistry including the origin of fossil fuels & the carbon cycle s role in controlling Earth s climate both in the geologic past & the rapidly changing present Geochemistry is essential reading for all earth science students as well as for researchers & applied scientists who require an introduction to the essential theory of geochemistry & a survey of its applications in the earth & environmental sciences Additional resources can be found at wwwwileycomgowhitegeochemistry
