An den hier behandelten barocken Kunstwerken treten bizarre Steinwucherungen auf, deren raison d¿être die Kunstwissenschaft kaum interessiert hat. Die zeitgenössischen geologischen Schriften stimmen darin überein, in den Steinen belebte, wachsende und vergehende Wesen zu sehen. Die Überschneidung dieser Vorstellungen mit den konkreten Felswucherungen an jenen Kunstwerken nötigt den Autor, ihre gesamte Ikonologie neu zu durchdenken. Seine Erkenntnisse lassen sich in diese Kernthesen fassen: Vierströmebrunnen: Die Erschütterung der Welt und ihre Beruhigung unter der Herrschaft Papst Innozenz¿ X. Palazzo di Montecitorio: Das aristotelische ¿Werden und Vergehen¿. Trevibrunnen: Das Wiedererwachen des Lebens nach der ¿Großen Flut¿.

This new edition of the classic textbook 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.

This book is the second volume of an edited work aiming to help novice geologists to explore terrains independently. Geoscience fieldwork with focus on structural geology and tectonics has become more important in the last few years from both academic and industrial perspectives. This book also works as a resource material for batches of students or geological survey professionals undergoing training as parts of their course curriculum/training. Industry persons, on the other hand, can get a first-hand idea about what to expect in the field, in case no academic persons are available with the team. This book focuses on structural geology and tectonics and compiles terrains from several regions of the globe. This book also includes field guide chapters for primary sedimentary structures.
