Über dieses Buch

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.

General Aspects of Metamorphism

Frontmatter
Chapter 1. Introduction to Metamorphic Rocks, Rock Metamorphism, and Metamorphic Processes
Abstract
Rock metamorphism denotes a geological process that typically changes the mineral assemblage.
Kurt Bucher
Chapter 2. Metamorphic Rocks
Abstract
Metamorphic rocks are the principal material of the planet earth.
Kurt Bucher
Chapter 3. Metamorphic Processes
Abstract
Metamorphism reworks existing rocks. The starting material, protolith, is being transformed.
Kurt Bucher
Chapter 4. Metamorphic Grade, Conditions of Metamorphism
Abstract
The intensity of metamorphism and the vigor of metamorphic transformation are expressed by the term metamorphic grade.

Chapter 5. Metamorphism of Ultramafic Rocks
Abstract
Ultramafic rocks are magnesium silicate rocks that normally contain no felsic minerals or very little (<10 vol%).
Kurt Bucher
Chapter 6. Metamorphism of Dolomites and Limestones
Abstract
Sedimentary carbonate rocks consist predominantly of carbonate minerals (as the name implies). There are two main types of carbonate rocks, dolomites and limestones. The first is modally dominated by dolomite (CaMg(CO3)2), the second by calcite (CaCO3) and there is a complete gradation between the pure dolomite and limestone “end members” indicated by the rock names, calcitic dolomite, dolomitic limestone, magnesian limestone.

Chapter 7. Metamorphism of Pelitic Rocks (Metapelites)
Abstract
Metapelites are probably the most distinguished family of metamorphic rocks. Typical examples include characteristic rocks and minerals such as chlorite-kyanite-schist, staurolite-garnet micaschist, chloritoid-garnet micaschist, kyanite-staurolite schist, biotite-garnet-cordierite gneiss, sillimanite-biotite gneiss and orthopyroxene-garnet granulite.
Kurt Bucher
Chapter 8. Metamorphism of Marls, Marlstones (Marlites)
Abstract
Marbles are metamorphosed sedimentary or igneous carbonate rocks. Metamorphism of carbonate-rich rocks produces a wealth of different types of marbles as discussed in Chap. 6. A prerequisite for the variety of mineral assemblages found in marbles is that a certain amount of minerals other than carbonates is present in the original carbonate sediment.
Kurt Bucher
Chapter 9. Metamorphism of Mafic Rocks
Abstract
Metamorphic mafic rocks (e.g. mafic schist or greenschist and mafic gneiss, amphibolite, mafic granulite) are derived from mafic igneous rocks, mainly basalt and andesite, and of lesser importance, gabbro and mafic diorite (Chap. 2; Fig. 9.1).
Kurt Bucher
Chapter 10. Metamorphism of Quartzofeldspathic Rocks
Abstract
Metamorphosed quartzofeldspathic rocks are derived from granitoid protoliths such as granite, alkali-feldspar granite, Qtz-syenite, granodiorite, tonalite and their extrusive equivalents such as rhyolite (Tables 2.2 and 10.1) and graywacke sandstone and siltstone (psammitic clastic sediments, Tables 2.2 and 10.2).
