Book Description
Concerned mainly with the preparation of samples and the interpretation of electron micrographs, whether of undisturbed samples, or of samples that have been deformed under laboratory conditions. The difficulties that arise in preparing undamaged samples for electron microscopy are discussed.

Book Description
Backscattered scanning electron microscopy (BSE) reveals the minerals, textures, and fabrics of sediments and rocks in much greater detail than is possible with conventional optical microscopy. Backscattered Scanning Electron Microscopy provides a concise summary of the BSE technique. This comprehensive guide uses abundant images to illustrate the type of information BSE yields and the application of the technique to the study of sediments and sedimentary rocks. The authors review the use of this petrographic technique on all the major sedimentary rock types, including sediment grains, sandstones, shales, carbonate rocks, rock varnish, and glauconite. They also describe image analysis techniques that allow quantification of backscattered scanning electron microscope images. Heavily illustrated and lucidly written, this book will provide researchers and graduate students with the most current research on this important geological tool.

Book Description
Knowledge of basic clay microstructure is fundamental to an understanding of the physical, chemical, and mechanical properties of fine-grained sediments and rocks. This compilation of fifty-nine peer-reviewed papers examines clay microstructure in detail with comprehensive sections focusing on microstructure signatures, environmental processes, modeling, measurement techniques, and future research recommendations. Many of these topics are discussed in light of geological and engineering applications, such as hazardous waste disposal, construction techniques, and drilling programs. The field of clay microstructure is developing rapidly. The concepts, observations, and principles presented in this book will help stimulate new thought and be a "spring board" for exciting new research.

Book Description
Over the past 20 years, synchrotron-based research applications have provided important insight into the geochemical cycling of ions and the chemical and crystallographic properties of minerals in soils and sediments. Of particular significance is the understanding of local coordination environments with the use of X-ray absorption spectroscopy. The high flux and brightness of the X-ray beams have allowed researchers to work at environmentally relevant concentrations. The use of focusing mirrors and apertures which allow for mapping and trace particle surfaces, microbes, roots, channels and elements at the micron and at a nano-meter scale in 2 and 3D have also been a great enhancement to science. This book provides the most up-to-date information on synchrotron-based research applications in the field of soil, sediment and earth sciences. Invited authors provide chapters on a wide range of research topics including multiphase flow and transport processes (physical aspects), rhizosphere and microbial life (biological aspects), and dynamics of C, N, S, P and heavy metals and metalloids (chemical aspects). In addition, perspectives on the impact of synchrotron based applications, particularly X-ray absorption spectroscopy, and the role of synchrotron applications in remediation, regulatory, and decision making processes are considered. Up-to-date, with the latest research results and techniques in synchrotron-based techniques Information on specific techniques, elements and minerals, regulatory and remediation decision making, contaminants and the impact of X-ray absorption spectroscopy on soil science Internationally recognized leaders in their fields of expertise from Europe, North America, Asia and Australia

Book Description
Sediment samples were taken from Gulf of Mexico cores. From these samples smaller ones were cut, freeze-dried and impregnated with Maraglas, an epoxy resin. Ultrathin sections of the impregnated samples were cut, and viewed in an electron microscope. Micrographs of the ultrathin sections revealed that the microstructures of most of the samples had a loose, open, random arrangement of particles. Differences in appearance of some of the microstructures are attributed to grain size variation, desiccation, remolding, and shearing of the sediment. Associated with this last factor is the formation of oriented domain structures. Variations among the samples in depth of burial, rate of deposition, and, particularly, clay mineralogy were generally small and resulted in no obvious differences in their microstructures. Cohesion, water content, and consolidation characteristics of samples were found to be generally indicative of the type of microstructure observed. Laboratory consolidation and desiccation of samples caused a 'collapse' of the microstructure and preferred, as well as non-preferred, orientation among the particles. Remolding of a sediment resulted in clumping of the particles, parallelism among the particles, and large voids. No evidence was observed in the micrographs which would substantiate the existence of a precipitated chemical cement. (Author).
