Pyroclastic Rocks
Springer Berlin (Verlag)
978-3-540-51341-4 (ISBN)
Pyroclastic Rocks is the first modern comprehensive treatment of what they are and how they were formed. The subject is discussed against a background of plate tectonics theory and modern advances in volcanology, sedimentology and igneous petrology. The book provides a thorough discussion of magmatic volatiles and pyroclastic processes as well as magma-water interactions. Most of the book is concerned with the wide spectrum of pyroclastic rocks formed on land and under water and by fallout and various flowage mechanisms. Diagenetic processes by which pyroclastic particles are transformed into rocks are discussed in detail. The stratigraphic and tectonic importance of pyroclastic rocks are illustrated using selected case histories. This uniquely integrated account of pyroclastic processes, particles and rocks will prove a valuable aid in reconstructing dynamic aspects of earth evolution as well as predicting future volcanic hazards.
Understanding sedimentary basins containing petroleum and gas deposits; locating ore deposits in volcanic complexes and heat sources in geothermal prospecting; and facilitating stratigraphic analysis in complex volcanic terrains.
Hans-Ulrich Schmincke war von 1983-91 Generalsekretär der International Association of Volcanology und war Direktor der Abteilung Vulkanologie und Petrologie am Geomar-Forschungszentrum in Kiel. Er hat zahlreiche nationale und internationale Auszeichnungen erhalten, darunter den höchsten deutschen Wissenschaftspreis, den Leibniz-Preis der Deutschen Forschungsgemeinschaft.
