Available in PDF, EPUB and Kindle. Book excerpt: Regional Studies and Specific Deposits deals with regional studies of strata-bound and stratiform ore deposits. Topics covered include the geological association between coal and metallic ores; the genesis of iron ores in banded iron-formation (BIF) by supergene and supergene-metamorphic processes; mineral zoning in sediment-hosted copper deposits; and the formation of gossans. The role of hydrothermal karst phenomena in the formation of Mississippi Valley-type deposits is also discussed. Comprised of five chapters, this volume begins with a review of the geological association of coal and metallic ores, focusing in particular on which metallic accumulations could be expected to be possibly present, within or close to the coal. The next chapter examines the origin of strata-bound enrichment deposits derived from BIF and presents the basic conceptual model for BIF-derived iron ores. The evolution of sulfide mineral zonation in low-temperature, sediment-hosted copper deposits is then evaluated. The book also describes the processes underlying the formation of gossans before concluding with an analysis of the hydrothermal karst phenomena as a factor in the development of Mississippi Valley-type deposits. This handbook will be useful to students, practitioners, and researchers in the fields of energy and earth sciences, mineralogy, mining, and metallurgy.

Available in PDF, EPUB and Kindle. Book excerpt: "Amber is a semi-precious gem that is formed over eons by natural forces out of the resin of trees. Human fascination with amber dates back to prehistoric times, when it was probably considered to have magical powers and was used for adornment and trade. Amber amulets and beads dating from 35,000 to 1,800 B.C. have been found, and where they have been found (for example in graves hundreds of miles from their chemically determined origins) has often helped to establish ancient trade routes." "The preservative qualities of plant resins were well known by the ancients. The Egyptians used resins to embalm their dead, and the Greeks used them to preserve their wine. Amber often preserved fossils, frequently in a pristine state, of all kinds of animal and plant organisms that made contact with the sticky substance and became trapped in it. These fossils include such fragile organisms as nematodes and mushrooms that ordinarily are not preserved under normal processes of fossilization, as well as larger organisms like scorpions and lizards, and the fossils are preserved in their full three-dimensional form, complete with minute details of scales, mouth parts, antennae, and hairs. It has even been suggested that viable DNA may persist in some amber-trapped organisms." "This book is a compendium of all that we know about life found in amber. It surveys all life forms, from microbes to vertebrates and plants, that have been reported from amber deposits throughout the world, beginning with the earliest pieces dating from some 300 million years ago. It also describes the formation of amber and the location, geological history, and early exploration of the major world amber deposits, including those still being worked today." "The book also provides practical information on how to determine fake amber containing present-day forms of life. It can serve as a beginning for tracing the geological history of a particular group of animals or plants or even reconstructing ancient paleoenvironments, and because amber fossils are preserved so completely, in a transparent medium, they can be intimately compared with related living species. Finally, the book discusses what amber fossils can tell us about evolution and speciation, cellular preservation, and paleosymbiosis." "The book is illustrated with 37 color photographs, 154 black-and-white photographs and drawings, and 8 maps."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Quaternary Glaciations Extent and Chronology written by J. Ehlers and published by Elsevier. This book was released on 2011-08-17 with total page 1128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls

Book excerpt: Provides the first comprehensive review of the current state of the science on tills It is critical that glacial scientists continue to refine their interpretations of ancient archives of subglacial processes, specifically those represented by tills and associated deposits, as they form the most widespread and accessible record of processes at the ice-bed interface. Unfortunately, despite a long history of investigation and a lexicon of process-based nomenclature, glacial sedimentologists have yet to reach a consensus on diagnostic criteria for identifying till genesis in the geological record. What should be called till? Based on the author’s extensive field research, as well as the latest literature on the subject, this book attempts to provide a definitive answer to that question. It critically reviews the global till literature and experimental and laboratory-based assessments of subglacial processes, as well as the theoretical constructs that have emerged from process sedimentology over the past century. Drawing on a wide range of knowledge bases, David Evans develops a more precise, contemporary till nomenclature and new investigatory strategies for understanding a critical aspect of glacial process sedimentology. Provides an in-depth discussion of subglacial sedimentary processes, with an emphasis on the origins of till matrix and terminal grade and the latest observations on till evolution Describes contemporary laboratory and modelling experiments on till evolution and techniques for measuring strain signatures in glacial deposits Develops an updated till nomenclature based on an array of knowledge bases and describes new strategies for field description and analysis of glacial diamictons Written by an internationally recognised expert in the field, this book represents an important step forward in the modern understanding of glacial process sedimentology. As such, Till: A Glacial Process Sedimentology is an indispensable resource for advanced undergraduates and researchers in sedimentology, glacier science and related areas.
