Pyroclastic Rocks

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.

This volume is an excellently written and beautifully illustrated textbook compiled by a multidisciplinary group of experts examining the production, transport and deposition of volcaniclasts (tephra and epiclasts) as well as their economic geology.

The unique and practical Materials Handbook (third edition) provides quick and easy access to the physical and chemical properties of very many classes of materials. Its coverage has been expanded to include whole new families of materials such as minor metals, ferroalloys, nuclear materials, food, natural oils, fats, resins, and waxes. Many of the existing families—notably the metals, gases, liquids, minerals, rocks, soils, polymers, and fuels—are broadened and refined with new material and up-to-date information. Several of the larger tables of data are expanded and new ones added. Particular emphasis is placed on the properties of common industrial materials in each class. After a chapter introducing some general properties of materials, each of twenty-four classes of materials receives attention in its own chapter. The health and safety issues connected with the use and handling of industrial materials are included. Detailed appendices provide additional information on subjects as diverse as crystallography, spectroscopy, thermochemical data, analytical chemistry, corrosion resistance, and economic data for industrial and hazardous materials. Specific further reading sections and a general bibliography round out this comprehensive guide. The index and tabular format of the book makes light work of extracting what the reader needs to know from the wealth of factual information within these covers. Dr. François Cardarelli has spent many years compiling and editing materials data. His professional expertise and experience combine to make this handbook an indispensable reference tool for scientists and engineers working in numerous fields ranging from chemical to nuclear engineering. Particular emphasis is placed on the properties of common industrial materials in each class. After a chapter introducing some general properties of materials, materials are classified as follows. ferrous metals and their alloys; ferroalloys; common nonferrous metals; less common metals; minor metals; semiconductors and superconductors; magnetic materials; insulators and dielectrics; miscellaneous electrical materials; ceramics, refractories and glasses; polymers and elastomers; minerals, ores and gemstones; rocks and meteorites; soils and fertilizers; construction materials; timbers and woods; fuels, propellants and explosives; composite materials; gases; liquids; food, oils, resin and waxes; nuclear materials. food materials

Developments in Geotechnical Engineering 6: Dams, Dam Foundations, and Reservoir Sites explores the design and construction of dams and reservoirs, and the foundations on which they rest. It discusses the theory and practice of geology and geophysics as they are applied to the study of proposed sites on which to build dams and reservoirs, the measures taken to ensure the continued safety of a dam during construction, and geological processes and features of foundations. Comprised of 10 chapters, this volume begins with an overview of the geotechnical aspects of planning and construction of dams and reservoirs, along with the origin, nature, and magnitude of problems associated with the foundation materials to be used. It then looks at the geological classification of natural substances and the strengths of these substances in terms of their origin, fabric, and mineralogy; excavation and filling of valleys; the influence of geologic structure in the development of erosional and depositional features in valleys; and the flow of water (seepage) beneath dams and around abutments. The reader is also introduced to groundwater hydrology as it relates to the movement of water through anisotropic materials beneath standing or running bodies of water at the Earth's surface and beneath dams; the mechanics of dam foundations; and excavations and dam construction in unconsolidated deposits. This book will be of interest to geologists, geophysicists, and engineers, as well as those involved in hydrology, geosciences, and rock and soil mechanics.
