Informationen zum Autor Harry Y. McSween! Steven M. Richardson! and Maria Uhle Klappentext 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 Zusammenfassung Intended for undergraduate and graduate geologists! this book focuses on how geochemical principles can be used to solve practical problems. It gives students a grasp of the basic principles of the subject! balancing the traditional equilibrium perspective and the kinetic viewpoint. Inhaltsverzeichnis Preface1.
