«Review of previous edition: 'The real quality of this book lies in its authoritative character and depth of coverage … a volume which will likely be well thumbed and littered with 'stickies' and other place markers by students and professors alike … one of the excellent aspects of the book is the clever integration of different aspects of petrology … a 'must-have' for any self-respecting petrologist.' Jon Davidson, Elements»

«Review of previous edition: 'I will choose the second edition of Philpotts and Ague's Principles of Igneous and Metamorphic Petrology because of its forward-looking coverage.' John M. Ferry, American Journal of Science»

«Review of previous edition: 'This is a book to read and a book to keep as a reference. It is a must-have for every student of tectonics.' Michael L. Williams, EOS»

«Review of this third edition: 'The 3rd edition of Principles of Igneous and Metamorphic Petrology follows in the footsteps of its previous editions. It not only covers the fundamentals of igneous and metamorphic petrology, but delves into many petrological aspects in great detail and thoroughness. The authors are to be commended on their outstanding quantitative treatment of petrological processes, supported by explanatory boxes of mathematical formulations. Clearly structured and richly illustrated with field and thin section photographs as well as sketches and diagrams, the book provides a comprehensive resource for those keen on acquiring an in-depth understanding of igneous and metamorphic processes.' Ralf Halama, Keele University»

«Review of this third edition: 'This is the definitive textbook on igneous and metamorphic petrology. Philpotts and Ague have found the perfect balance between ensuring that the content is accessible to students while avoiding oversimplification. I will continue to use this textbook in my online and campus courses.' Alasdair Skelton, Stockholm University»

«Review of this third edition: 'This third edition of Philpotts and Ague builds upon an excellent record of textbooks focusing on igneous and metamorphic petrology. The book is comprehensive in its coverage of the processes involved in the petrogenesis of igneous and metamorphic rocks and the implications of these processes, is well illustrated with excellent diagrams and images throughout, and will be useful for a range of geoscientists from upper-level undergraduate students to graduate students and faculty, for both teaching and research. This edition is well supplemented by online resources that are ideally suited for teaching, including all of the figures in the textbook in digital formal and a solutions manual for instructors. Overall, I highly recommend this book and strongly suspect well-thumbed versions will end up on the shelves of many geologists worldwide.' Simon Jowitt, University of Nevada»

«Review of this third edition: 'The 3rd edition of Principles of Igneous and Metamorphic Petrology is a detailed and well-illustrated textbook that lays out analytical petrologic methods in a clear, comprehensive manner. Extensive examples are given throughout to thoroughly elucidate complex topics and mathematical formulations. One standout feature that sets this textbook apart from others are the end-of-chapter questions. These questions are divided into quantitative and broad topics, facilitating multiple levels of student mastery and allowing for the text to be used at both the undergraduate and graduate levels. Much as I still regularly consult my copy of the 1st edition of this book many years after using it as an undergraduate, the 3rd edition …  should be a mainstay of every petrology student's bookshelf.'
