Petrogenesis of Metamorphic Rocks : Complete Revision of Winkler's Textbook

Metamorphic rocks are one of the three classes of rocks. Seen on a global scale they constitute the dominant material of the Earth. The understanding of the petrogenesis and significance of metamorphic of geological education. rocks is, therefore, a fundamental topic There are, of course, many different possible ways to lecture on this theme. This book addresses rock metamorphism from a relatively pragmatic view point. It has been written for the senior undergrad­ uate or graduate student who needs practical knowledge of how to interpret various groups of minerals found in metamorphic rocks. The book is also of interest for the non-specialist and non-petrolo­ gist professional who is interested in learning more about the geolo­ gical messages that metamorphic mineral assemblages are sending, as well as pressure and temperature conditions of formation. The book is organized into two parts. The first part introduces the different types of metamorphism, defines some names, terms and graphs used to describe metamorphic rocks, and discusses principal aspects of metamorphic processes. Part I introduces the causes of metamorphism on various scales in time and space, and some principles of chemical reactions in rocks that accompany metamorphism, but without treating these principles in detail, and presenting the thermodynamic basis for quantitative analysis of reactions and their equilibria in metamorphism. Part I also presents concepts of metamorphic grade or intensity of metamorphism, such as the metamorphic-facies concept. The new edition of Winkler's textbook, completely revised by K. Bucher and M. Frey, is written at the same level as the preceding editions. Numerous diagrams showing the stability relations among minerals found in metamorphic rocks help to determine the pressure and temperature conditions under which a given set of metamorphic rocks may have formed. Part I explains basic principles of metamorphism, introduces metamorphic processes and geologic thermobarometry, and defines metamorphic grade. Part II presents in a systematic way mineralogical changes and assemblages found in the most common types of rocks. The computation of the diagrams is based on recent advances in quantitative petrology and geochemistry.

It explains metamorphism and presents information on the mineralogical changes and assemblages found in the most common types of rocks. The process of rock metamorphism changes the mineralogical and chemical composition, as well as the structure of rocks.
