Principles of igneous and metamorphic petrology /

This revised edition of the classic 1990 work by Philpotts and Ague (both, Yale) is unquestionably the best petrology work available. The authors' quantitative approach emphasizes thermodynamic principles that are essential to thoroughly understanding petrologic processes, but commonly shortchanged in similar books. The volume includes abundant new material on the properties/behavior of magmas and the nature of Earth's mantle and core along with recently developed software programs designed for image analysis and calculation of phase equilibria. The format, similar to the first edition, is subdivided into predominantly igneous and metamorphic sections, with cross-references where relevant material applies to both sections. Following an introduction, chapters cover the physical properties/intrusion of magmas, cooling, diffusion processes and forms of igneous bodies, rock classification, thermodynamics and phase equilibria as applied to igneous systems, effects of volatiles, crystal growth, influence of isotopes, magmatic processes, and igneous rock associations. Subsequent chapters address processes of metamorphism, metamorphic rock facies, fabric, mineral reactions in solids, and more. A final chapter discusses the ultimate origin of Earth's rocks and the processes involved in their genesis. The book contains numerous illustrations, up-to-date references, quantitative problem sets, and a thorough index. Superbly suited for intermediate/advanced petrology students and practicing professionals. Summing Up: Highly recommended. Upper-division undergraduate through professional collections. M. E.
