B. Ronald Frost and Carol D. Frost (2013) Cambridge University Press, U.K. ISBN: 9781107696297, 314 pages. Essentials of Igneous and Metamorphic Petrology , which is easy to recommend, is presented in a concise and compelling manner. The book is about 300 pages and is subdivided into eighteen chapters that convey the fundamental principles that govern the mineralogy of igneous and metamorphic rocks. The authors, B. Ronald Frost and Carol D. Frost, each have a strong track record in these fields. The target audience is introductory-level geoscience students. Students in particular will benefit from both authors’ decades of experience teaching the subject matter to undergraduates. Their experience has been condensed in this book. The first part of the book (ten of the eighteen chapters) introduce igneous petrology, while the remaining eight chapters provide an introduction to metamorphic petrology. Both topics are developed independently, allowing the reader to focus on each subject area separately. The general format of the chapters is uniform throughout the book. …
