The safe disposal of radioactive wastes by burial in deep geological formations requires long-term predictions of the future behaviour of the wastes and their engineered repository. Such predictions can be tested by evaluating processes analogous to those which will occur in a repository, which have been long active in the natural geochemical environment. The Pocos de Caldas Project is a comprehensive study of two ore deposits in Minas Gerais, Brazil, aimed at looking at uranium and thorium series radionuclide and rare-earth element mobility, the development and movement of redox fronts, and the nature of natural groundwater colloids. A multidisciplinary team of experts from 27 laboratories carried out a fully integrated study of the geology, geomorphology, hydrogeology, geochemistry, hydrochemistry and geomicrobiology of the two sites for nearly four years. This book contains 20 papers covering the detailed findings, with particular emphasis on their significance for radioactive waste disposal, especially on the use of the data in testing models of radionuclide movement. It will interest economic geologists, geochemists and performance assessment modellers involved in the geological disposal of radioactive wastes.

In 1980, Nagra, the Swiss National Cooperative for the Storage of Radioactive Waste, began a comprehensive field investigation programme to assess the feasibility and safety of a repository for the final disposal of high-level radioactive waste in northern Switzerland. An international team of scientists has carried out a comprehensive study on the isotope hydrogeology of deep groundwaters. One of the major implications of this work pertains to the storage of radioactive waste. The study goes far beyond an in-depth regional study as it draws together the results of diverse techniques, many of which have been re-evaluated or further developed.This book presents in great detail the results of one of the most comprehensive isotope hydrology studies ever undertaken.

This book covers the more basic aspects of carbonate minerals and their interaction with aqueous solutions; modern marine carbonate formation and sediments; carbonate diagenesis (early marine, meteoric and burial); the global cycle of carbon and human intervention; and the role of sedimentary carbonates as indicators of stability and changes in the Earth's surface environment. The selected subjects are presented with sufficient background information to enable the non-specialist to understand the basic chemistry involved. Tested on classes taught by the authors, and approved by the students, this comprehensive volume will prove itself to be a valuable reference source to students, researchers and professionals in the fields of oceanography, geochemistry, petrology, environmental science and petroleum geology.

Carbonate Diagenesis and Porosity

Carbonate diagenesis is a subject of enormous complexity because of the basic chemical reactivity of carbonate minerals. These carbonate minerals react quickly with natural waters that either dissolve the carbonates, or precipitate new carbonates to bring the water into equilibrium with the host carbonate sediments and rocks. These rock-water interactions either create porosity by dissolution, or destroy porosity by the precipitation of carbonate cements into pore spaces. Carbonate Diagenesis and Porosity examines these important relationships in detail.This volume is published in co-operation with OGCI, and is based on training courses organised by OGCI and taught by Dr. Moore. It is intended to give the working geologist and university graduate student a reasonable overview of carbonate diagenesis and its influence on the evolution of carbonate porosity. It starts with a discussion of the major differences between carbonates and siliciclastics so that the novice will have an appreciation of the basic nature of the carbonate system. Carbonate porosity, its nature and its classification is then discussed so that the relationship between diagenesis and porosity can be established. Environments of diagenesis and their characteristics are outlined, stressing the nature of pore fluids found in each environment. Tools for the recognition of these environments are then discussed with stress on the constraints suffered by each technique. Each major diagenetic environment is then discussed in detail with petrographic, geochemical characteristics outlined, and an in depth discussion of the impact of the environment's diagenetic processes on porosity development and evolution. Diagenetic models are developed where appropriate and criteria for recognition listed. Case histories illustrating these concepts and models are presented for each major diagenetic environment and sub-environment.Over 160 line drawings illustrate the book. Petrographic characteristics of porosity and diagenetic fabrics and textures are illustrated using numerous photomicrographs taken specifically for the book by the author. The book has been extensively indexed, and includes a large, current reference section.This book should be useful to any geologist interested in, or working with, carbonate sediments and rocks. It will be particularly useful to the industrial geologist concerned with the exploration or exploitation of hydrocarbons from carbonate rock sequences where an understanding of porosity development, evolution, and prediction are important. In addition, this book will be a good text for advanced carbonate courses at graduate level, and an appropriate reference book for graduate students working in, or interested in, carbonate rock sequences and sediments.

``Semimetals'' presents, for the first time in the literature, a consistent and unifying treatment of semimetals (As, Bi, Sb, Bi-Sb alloys, graphite and its compounds). It describes their structural features and their electric, magnetic, galvanomagnetic, thermoelectric, optical, magneto-optical, acoustic, thermal, and mechanical properties on the basis of modern concepts of the electron and phonon energy spectra.The book discusses in detail the character of the changes in the energy spectrum and properties of semimetals due to temperature variations, application of a magnetic field, pressure, anisotropic strain, doping by donor, acceptor and neutral impurities, which indicate how the above properties may be altered and how materials with preassigned parameters can be produced. Furthermore, it discusses specific phenomena associated with low dimensionality and the very low carrier density, such as quantum oscillations and magnetoplasma behaviour.

Despite the large number of papers and books published on soil organic matter (humus), our knowledge of the subject is still very limited, as is our knowledge of humic acid. The author of this book began to study humus at the end of the 1940s and continued until 1984 when he retired from Nagoya University. With the intention of establishing a systematic understanding of soil organic matter, he has compiled facts and a discussion of humus based on his extensive experimental results during the past 40 years.In this book, humic acids are classified into A, B, Rp and P types, based on their optical properties. The elementary composition and other chemical properties of humic acid types are shown to be regularly different from each other. A new method for humus composition analysis applied to various kinds of soils in Japan and several other countries indicates that the diversity of humus compositions of soils is systematically understandable. These findings lead the author to novel theories on the chemical configuration and formation of humic acids and humic substances. Diagenesis of humus under terrestrial conditions is illustrated as to the buried humic horizons of Black soil (Andosol).The book will be useful not only to soil scientists and agronomists but also to geochemists, oceanographers, limnologists, water scientists, biologists and chemists who are dealing with organic matter in terrestrial, aquatic, and sedimentary environments.

Developments in Economic Geology, 16: Geochemical Prospecting for Thorium and Uranium Deposits focuses on the analysis of various geochemical methods applicable in the search for all types of thorium and uranium deposits. The publication first ponders on the general chemistry and geochemistry of thorium and uranium, deposits of thorium and uranium and their indicator elements, and geochemical prospecting for thorium and uranium. Discussions focus on radiation surveys, selection of areas, primary mineralization, supergene oxidation, and secondary enrichment of endogenic thorium and uranium deposits, and equilibrium in the natural radioactive series. The book then ponders on lithochemical, pedochemical, hydrochemical, and biogeochemical surveys of the geochemical prospecting for thorium and uranium. Topics include heavy and light mineral surveys of stream, river, pond, and lake sediments, detailed litochemical surveys utilizing primary halos, and case histories. The text takes a look at sampling procedures and analytical methods for estimating thorium and uranium and miscellaneous methods and atmochemical surveys on the geochemical prospecting for thorium and uranium, including isotopic methods, remote sensing and geothermal methods, and liquid inclusion and thermoluminescent methods. The book is a valuable source of data for researchers wanting to explore geochemical prospecting for thorium and uranium deposits.

Starting from the basic features of crystal morphology and symmetry without assuming that the reader knows anything about crystals this textbook shows how they provide an insight into the way in which crystals are based on a repeating pattern of atoms. After summarizing and comparing the main features of the seven crystal systems and thirty-two crystal classes, the book goes on to treat X-ray crystallography in sufficient detail to provide an understanding of its uses in identification and in textural and structural studies, and to relate it to selected area electron diffraction methods in the electron microscope. Thus the student is brought to a level where he can understand the significance of crystallographic work, and has a thorough background if he wishes to move on to more specialist works. Problems and answers are included
