"Petrology" 3rd edition successfully builds upon the strengths of its predecessor, but now also includes fresh and engaging features to bring the book to the forefront of today’s teaching. New chapters on Volcanism, new appendices and sharper photos make this a must-have for all students of petrology. In addition to these changes, "Petrology" has been thoroughly updated throughout and remains the only text of its kind to cover all three different rock types.
