With enough background to be rigorous, yet not exhaustive, this book offers good preparation in the techniques of modern petrology; a clear and organized review of the classification, textures, and approach to petrologic study; and applies these concepts to the real occurrences of the rocks themselves. The goal throughout is for readers to be able to apply the techniques—and enjoy the insights of the results—rather than tinker with theory and develop everything from first principles. A survey of actual occurrences of igneous and metamorphic rocks, and processes that produce them, is provided. This section is often greatly condensed in most other books, but it is the most interesting and dynamic aspect of petrology.
