Because me- morphic rocks are not only what they are, but also what they were, and they tell of what happened in between. What must be discovered: how to recognize in the butterfly, the caterpillar that was, or in the caterpillar the butterfly that will be? And how to describe the metamorphosis, excuse me, metamorphism which leads from one to the other? It is to this engaging history, this marvelous tale, written progressively over time, which Jacques Kornprobst leads us. If the sedimentary and magmatic rocks have been the object of reflection for a long time, for which a contradiction was established in the century in the confrontation between the Neptunism of Werner for whom everything came from the sea, and the P- tonism of Hutton who derived all rocks from the interior of the earth, the “crystalline schists” as they were called, and as we call them today for simplicity, appear most ambi- ous: they had the crystals of rocks of endogenous origin and appeared to have the strati- cation of exogenous rocks with which one confused the schistosity. These crystalline schists are in some ways the bats of the rock kingdom.

Available in PDF, EPUB and Kindle. Book excerpt: This book is about metamorphic rocks: the processes involved in their formation and the reasons why they occur at particular places on the continents. It has been written to serve as an elementary text on the subjects of metamorphism and mountain building for non-specialist stu dents of geology. It will be equally useful where geology is either the main or subsidiary subject and could be used by students intending to advance further in geology (the list of advanced texts in the further reading section would be more appropriate to such students). My inten tion in writing this book has been to try to dispel the notion that metamorphism comprises the 'haunted wing' of geology. Admittedly, there are rather a large number of technical terms in the book, but I hope that after working through it you will not find metamorphism an unduly difficult or obscure aspect of geology. Throughout, I have emphasised the strong links between mountain building, plate tectonics and metamorphic processes. The book introduces metamorphic rocks by considering their textures and field relations, then moves on to deal with the factors controlling metamorphism. Case studies of areas of metamorphic rocks are then presented in the context of modern theories of the Earth's activity, and the place of metamorphic rocks in the formation of ancient and young mountain belts is analysed. New technical terms and concepts are explained in context as they are introduced, important terms being emphasised in bold print.

Available in PDF, EPUB and Kindle. Book excerpt: Petrogenesis of Metamorphic Rocks presents a large number of diagrams showing the stability relations among minerals and groups of minerals found in metamorphic rocks. The diagrams help to determine the pressure and temperature conditions under which a given set of metamorphic rocks may have formed. Other parameters that control metamorphic mineral assemblages are also discussed and pitfalls resulting from simplifications and generalizations are highlighted. The book discusses the most common metamorphic rock types, their nomenclature, structure and graphical representation of their mineral assemblages. Part I defines basic principles of metamorphism, introduces metamorphic processes, geologic thermometry and barometry and defines metamorphic grade. Part II presents in a systematic way mineralogical changes and assemblages found in the most common types of metamorphic rocks. The computation of diagrams is based on recent advances in quantitative petrology and geochemistry. An extensive bibliography, including the key contributions and classic papers in the field, make it an invaluable source book for graduate students and professional geologists.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: There has been a great advance in the understanding of processes of meta morphism and of metamorphic rocks since the last edition of this book appeared. Methods for determining temperatures and pressures have become almost routine, and there is a wide appreciation that there is not a single temperature and pressure of metamorphism, but that rocks may preserve, in their minerals, chemistry and textures, traces of their history of burial, heating, deformation and permeation by fluids. However, this excit ing new knowledge is still often difficult for non-specialists to understand, and this book, like the first edition, aims at enlightenment. I have concen trated on the interpretation of the plate tectonic settings of metamorphism, rather than following a geochemical approach. Although there is an impress ive degree of agreement between the two, I believe that attempting to discover the tectonic conditions accompanying rock recrystallization will more readily arouse the interest of the beginner. I have used a series of case histories, as in the first edition, drawing on my own direct experience as far as possible. This m

Available in PDF, EPUB and Kindle. Book excerpt: Rocks, more than anything else, underpin our lives. They make up the solid structure of the Earth and of other rocky planets, and are present at the cores of gas giant planets. We live on the rocky surface of the planet, grow our food on weathered debris derived from rocks, and we obtain nearly all of the raw materials with which we found our civilization from rocks. From the Earth's crust to building bricks, rocks contain our sense of planetary history, and are a guide to our future. In this Very Short Introduction Jan Zalsiewicz looks at the nature and variety of rocks, and the processes by which they are formed. Starting from the origin of rocks and their key role in the formation of the Earth, he considers what we know about the deep rocks of the mantle and core, and what rocks can tell us about the evolution of the Earth, and looks at those found in outer space and on other planets. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Available in PDF, EPUB and Kindle. Book excerpt: The North American Cordillera is arguably the most well studied example of a long-lived accretionary orogen on Earth, and yet -- despite nearly a century-and-a-half of geologic study -- profoundly fundamental questions persist about its tectonic, metamorphic and magmatic evolution. These questions bear on the initiation and geodynamic drivers for deformation, the reasons for observed along-strike variations, the maximum thickness of the crust achieved during shortening events, the thermal evolution of thickened crust through time, and the timing and geodynamic drivers of the "collapse" of thick crust. Due to variable but often significant tectonic and metamorphic overprinting, studies to address the above questions require analytical techniques and tools that can peer through younger overprinting events. This thesis utilizes a combination of modern and classical geologic methods, including geologic mapping, structural analysis, U-Pb geochronology, metamorphic petrology, 40Ar/39Ar thermochronology, igneous petrology, isotopic geochemistry, and non-classical thermobarometry to peer through metamorphic overprints so as to refine our understanding of several important tectonic developments within the long-term evolution of the Cordillera orogen. This thesis characterizes and attempts to solve some outstanding questions and problems presented by metamorphic rocks exposed in the southern Brooks Range of Alaska and the Snake Range of Nevada which provide insights into the nature of lithospheric-scale processes that accompany continental orogenesis during both shortening and extension. A main focus of this thesis (Chapter 1) has been to reconcile field-based upper-crustal structural reconstructions with metamorphic and igneous processes occurring deeper in the crust in settings where these data sets are in conflict with one another. Specifically, in the northern Snake Range metamorphic core complex, Nevada, and in other similar settings, classical thermobarometry suggests that footwall rocks were buried twice as deep (> 8 kbar) as indicated by structural reconstructions based on geologic mapping (~4 kbar). Decades of disagreement have led to a variety of widely incongruent models for the burial and uplift of these rocks, most of which have since been applied globally. Chapter 1 evaluates the possibility of cryptic structures responsible for burial and exhumation from such depths and presents an independent test of the high pressure estimates with quartz-in-garnet piezothermobarometry and Ti in quartz thermobarometry. The discordance between paleo-depth determined from structural reconstructions and paleo-depth implied by > 7 kbar pressure estimates leads to the suggestion that Cordilleran metamorphic core complexes may have experienced super-lithostatic conditions due to shallow partial melting and increased deviatoric stresses in a region characterized by anomalously high geothermal gradients. A second focus of this thesis (Chapters 2-4) has been to better characterize the geology and tectonic history of the Arctic Alaska terrane, which has a history that links the Cordillera to the Arctic-North Atlantic region, where many terranes in the Canadian and western U.S. Cordillera are believed to have originated. Chapter 2 characterizes the growth of greenschist-facies metamorphic zircon within an extensive south-dipping extensional shear zone developed along the southern margin of the Brooks Range. This shear zone is interpreted as the result of a geodynamic switch in the Pacific subduction system that led to trench retreat / slab rollback just prior to the c. 115 Ma U-Pb ages of zircon in the normal sense shear zone. Chapter 3 utilizes detrital zircon "fingerprints" to better locate an important mid-Paleozoic suture within the Brooks Range of Arctic Alaska that provides an important geologic tie-point for paleogeographic reconstructions. Chapter 4 builds on this improved understanding of the crustal suture and paleogeography of the Arctic to show that establishment of subduction along the Cordilleran continental margin in the Devonian is the likely result of a major plate reorganization event during the latest stages of or post-dating the Caledonian orogeny. Together, these chapters support interpretations that the Cordilleran margin has been defined by cyclical advance and retreat of arc-barckarc systems since at least c. 400 Ma.

Book excerpt: Many common terms in metamorphic petrology vary in their usage and meaning between countries. The International Union of Geological Sciences (IUGS) Subcommission on the Systematics of Metamorphic Rocks (SCMR) has aimed to resolve this, and to present systematic terminology and rock definitions that can be used worldwide. This 2007 book is the result of discussion and consultation lasting 20 years and involving hundreds of geoscientists worldwide. It presents a complete nomenclature of metamorphic rocks, with a comprehensive glossary of definitions, sources and etymology of over 1200 terms, and a list of mineral abbreviations. Twelve multi-authored sections explain how to derive the correct names for metamorphic rocks and processes, and discuss the rationale behind the more important terms. These sections deal with rocks from high- to low- and very-low-grade. This book will form a key reference and international standard for all geoscientists studying metamorphic rocks.
