One of the fundamental objectives of physical geochemistry is to understand the evolution of geochemical systems from microscopic to regional and global scales. At present there seems to be a general recognition of the fact that internal properties of minerals record important aspects of the evolutionary history of their host rocks which may be unraveled by very fine scale observations. A major focus in the development of geochemical research in the last thirty years has been the application of classical thermodynamics to reconstruct the conditions at which the states of quenched mineralogical properties of rocks have equilibrated during the course of their evolution. While these works have funda­ mentally influenced our understanding ofthe physico-chemical history ofrocks, in recent years petrologists, mineralogists, and geochemists have been making greater efforts towards the application of kinetic theories in order to develop a better appreciation of the temporal details of geochemical processes. The present volume brings together a variety of current research on transport in systems of geochemical interest from atomic to outcrop scales. A major theme is atomic migration or diffusion, and its various manifestations on microscopic and macroscopic scales. Transport in the solid state is controlled by diffusion and is responsible for the states of atomic ordering and relaxation of composi­ tional zoning in minerals, development of compositional zoning during cooling, exsolution lamellae, and creep.

This book presents the fundamental principles of Classical thermodynamics, supplemented by  an overview of Statistical Thermodynamics, and explores their applications to a wide variety of problems in the Earth and Planetary sciences, spanning the range from the Earth’s core, mantle and crust, aqueous solutions and fluid-rock interactions to solar nebula, terrestrial planets and asteroids. The topics covered include the laws of classical thermodynamics, microscopic foundations of thermodynamic properties, critical phenomena and near-critical processes, equations of state, phase transitions and phase equilibria, the Earth’s interior and adiabatic processes, terrestrial magma ocean, thermodynamics of solutions, element and stable isotope fractionations, electrolyte solutions and electrochemistry, osmotic processes, surface effects, entropy production and kinetic implications, thermodynamics of chemical diffusion, estimation of thermochemical properties, and mathematicalmethods of classical thermodynamics. There is also a wealth of solved problems relating to both fundamental concepts and applications to natural processes.
