First time that a western-based book on China's geology and mineral deposits is published Appropriate for use by the mineral exploration industry Modern English-language geological and mineral deposits information on China Most useful to Western (and Chinese) geoscientists

Urban subsurface resources and particularly urban groundwater are vulnerable to environmental impacts, and their rational management is of major importance. In this book a multidisciplinary team of specialists and scientists presents innovative process-oriented approaches to the sustainable use of these resources. The included case studies from northwestern Switzerland describe representative environments and are relevant for urban areas in general. They illustrate the protection of groundwater; river restoration; engineering and hydrogeological questions related to urban infrastructure and management concepts; as well as monitoring, modeling and remediation strategies for contaminated sites; problems caused by karst in urban environments; the use of shallow geothermal energy; and natural hazards such as flood events and earthquakes. It is demonstrated that modern quantitative earth sciences can contribute significantly in finding solutions concerning the sustainable use of subsurface resources in urban environments. The book is an invaluable source of information for hydrogeologists, geologists, urban planners, water supply engineers, and environmental agencies.

Sidescan sonar is proving to be the preeminent technique for researchers and professionals seeking knowledge about the structure and behavior of the seafloor, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. This book covers the fundamentals of sidescan sonar, incorporates new understanding of marine structures, and explains how to interpret sidescan sonar imagery and bathymetry.

This ground-breaking work is the first to cover the fundamentals of hydrogeophysics from both the hydrogeological and geophysical perspectives. Authored by leading experts and expert groups, the book starts out by explaining the fundamentals of hydrological characterization, with focus on hydrological data acquisition and measurement analysis as well as geostatistical approaches. The fundamentals of geophysical characterization are then at length, including the geophysical techniques that are often used for hydrogeological characterization. Unlike other books, the geophysical methods and petrophysical discussions presented here emphasize the theory, assumptions, approaches, and interpretations that are particularly important for hydrogeological applications. A series of hydrogeophysical case studies illustrate hydrogeophysical approaches for mapping hydrological units, estimation of hydrogeological parameters, and monitoring of hydrogeological processes. Finally, the book concludes with hydrogeophysical frontiers, i.e. on emerging technologies and stochastic hydrogeophysical inversion approaches.

This monograph focuses on the numerical methods needed in the context of developing a reliable simulation tool to promote the use of renewable energy. One very promising source of energy is the heat stored in the Earth's crust, which is harnessed by so-called geothermal facilities. Scientists from fields like geology, geo-engineering, geophysics and especially geomathematics are called upon to help make geothermics a reliable and safe energy production method. One of the challenges they face involves modeling the mechanical stresses at work in a reservoir. The aim of this thesis is to develop a numerical solution scheme by means of which the fluid pressure and rock stresses in a geothermal reservoir can be determined prior to well drilling and during production. For this purpose, the method should (i) include poroelastic effects, (ii) provide a means of including thermoelastic effects, (iii) be inexpensive in terms of memory and computational power, and (iv) be flexible with regard to the locations of data points. After introducing the basic equations and their relations to more familiar ones (the heat equation, Stokes equations, Cauchy-Navier equation), the "method of fundamental solutions" and its potential value concerning our task are discussed. Based on the properties of the fundamental solutions, theoretical results are established and numerical examples of stress field simulations are presented to assess the method's performance. The first-ever 3D graphics calculated for these topics, which neither requiring meshing of the domain nor involving a time-stepping scheme, make this a pioneering volume.

A timely review of state-of-the-art tsunami research, covering case studies and recent developments from various approaches. Provides a practical guide to improving operational tsunami warning systems and mitigating coastal hazard from tsunamis.

Just a few meters below the Earth's surface lie features of great importance, from geological faults which can produce devastating earthquakes, to lost archaeological treasures. This refreshing, up-to-date book explores the foundations of interpretation theory and the latest developments in near-surface techniques, used to complement traditional geophysical methods for deep-exploration targets. Clear but rigorous, the book explains theory and practice in simple physical terms, supported by intermediate-level mathematics. Techniques covered include magnetics, resistivity, seismic reflection and refraction, surface waves, induced polarization, self-potential, electromagnetic induction, ground-penetrating radar, magnetic resonance, interferometry, seismoelectric and more. Sections on data analysis and inverse theory are provided and chapters are illustrated by case studies, giving students and professionals the tools to plan, conduct and analyze a near-surface geophysical survey. This is an important textbook for advanced-undergraduate and graduate students in geophysics and a valuable reference for practising geophysicists, geologists, hydrologists, archaeologists, and civil and geotechnical engineers.

Magnetotactic bacteria (MTB) synthesize intracellular nano-sized minerals of magnetite and/or greigite magnetosomes for magnetic orientation. They play important roles in global iron cycling and sedimentary magnetism, and have a broad range of potential applications in both biotechnological and biomedical fields. However, because the majority of MTB in nature remain unculturable, our understanding of these specific bacteria remains fairly limited. This thesis describes the development of a novel approach for effectively collecting, purifying and characterizing uncultivated magnetotactic bacteria. The diversity, genomic information and rock magnetic properties of various uncultivated MTB are investigated and characterized using a combination of biological and geophysical methods. The results will lead to a better understanding of the biogeography and biomineralization mechanisms of MTB in nature, and improve our knowledge of the contributions of MTB to biogeochemical cycles of elements and sedimentary magnetism.

The contributions to the 151st IAU Colloquium cover different fields of recent research, observational as well as theoretical, on solar and stellar flares ranging from radio up to gamma-ray wavelengths. A special chapter is devoted to all-sky monitoring and, finally, the excerpts of a round-table discussion present the reader with an interesting outlook on future developments. This book is therefore a unique source for those who want to get a complete picture of this fascinating part of modern astrophysics.

These workshop proceedings aim to provide a broad overview of recent developments in the study of hot stars, both from the observational and the theoretical point of view. Included are first results from the Hubble Space Telescope and ROSAT, the effects of non-radial pulsations, mass loss, magnetic fields, and diffusion, as well as modern theoretical methods to treat radiative transfer and compute model atmospheres. Many new results are described, including the discovery of a B star in the halo of M31. Together the reviews provide a general overview of hot-star spectroscopy suitable for preparing advanced lecture courses and as an introductory text for graduate students.

The subject of the book, the ubiquitous circumstellar disks around very young stars and the corresponding jets of outflowing matter, has recently become one of the hottest areas in astrophysics. The disks are thought to be precursors to planetary systems, and the outflows are thought to be a necessary phase in the formation of a young star, helping the star to get rid of angular momentum and energy as it makes its way onto the main sequence. The possible connections to planetary systems and stellar astrophysics makes these topics especially broad, appealing to generalists and specialists alike. The CD not only contains papers that could not be printed in the book but allows the authors to include a fair amount of data, often displayed as color images.

Based on Cretaceous-Tertiary accretionary sequences of the Shimanto Belt in Japan, the complex history of these exceptionally exposed rocks is summarized through a series of outcrop- to microscopic scale photographs, sketches, and geological maps, most of which are in full colour. This atlas broadens the base of general knowledge of the growth of continental margins, and provides both a general introduction to research in accretionary prisms as well as an education aid for students in sedimentology, structural geology and tectonics.

In the Spring of 2000 the idea of a consortium of Mediterranean countries support- ing the Italian bid to host the 32nd International Geological Congress took off during ageological fieldtrip on the slopes ofMountVesuviushosted byProf. Bruno D'Argenio (University of Naples) with the sponsorship of SMED(the UNESCO-CNR Office for Scientific and Technological Cooperation with Mediterranean Countries). On that st occasion, the head of the Italian delegation to the coming 31 IGCProf. Gian Battista Vaichampionedthe notionthat - had the bid been accepted - such cooperationshould have not only translated into the participation of the Mediterranean countries in the organization of the future congress, but also should have been a springboard for launching a scientific project focused on the Mediterranean region and whose re- sults had to be presented at the congress. st During the 31 IGCin Riode Janeiro,after the designation of Florence bythe lUGS nd Council as the venue for the 32 IGC,the Mediterranean Consortium was set up. In its full configuration, the Consortium was an association of thirty-one Mediterra- nean and nearbycountries. Alongwith Italy,they are:Albania,Algeria,Austria, Bosnia- Herzegovina, Bulgaria, Croatia, Cyprus, Egypt, France, Greece, Hungary, Iran, Iraq, Israel, Jordan, Lebanon, Libya,Macedonia, Malta,Morocco,Palestine, Romania, Saudi Arabia, Serbia and Montenegro, Slovakia,Slovenia,Spain, Switzerland, Syria,Tunisia, and Turkey. Each member country nominated a National Representative who served as a liai- son between his/her national geological community and the IGCOrganizing Commit- tee.

There have been considerable advances in recent times in understanding many common material processes that are of practical importance, such as nonlinear response, fracture, breakdown, earthquakes, packing, and granular flow, that are of immense practical importance. This has been mainly due to new applications of statistical physics, including percolation theory, fractal concepts and self-organized criticality. This collection of articles brings together research in those closely allied fields. It deals with problems in material science involving random geometries and nonlinearity at a mesoscopic scale, where local disorder and nonlinearity influence the global behaviour of cracks, for example, and problems where randomness in time evolution is as crucial as the geometry itself.

The book reviews the knowledge obtained from ground-based and space-borne solar flare research thus at the same time preparing for the forthcoming mission of the satellite Solar A which will be launched in 1991. Accordinglyone section is devoted to experiments on Solar A. The rest review both theory and observational facts to give a physically realistic picture of flares, including problems of magnetic flux emergence, high energy particles in flares, heating and flows in flares, and further problems of solar activity.

These proceedings give a rather complete overview of the most recent research in the areas of fundamental processes and phase transitions, cloud droplet and ice nucleation in the atmosphere, and aerosol formation and aerosol characteristics in the atmosphere. Nine review papers on topics of special importance are supplemented by about 200 summaries on topics of greatest current importance. The volume should be of interest to scientists working in the atmospheric and environmental sciences, in chemistry and in physics, as well as to engineers working in these areas.

This volume offers an account of the scientific outcome of a Priority Programme (Schwerpunktprogramm) which the Deutsche Forschungsgemein- schaft (DFG; German Research Society) promoted during 6 years from 1976 to 1982. In the understanding of the DFG, a Priority Programme involves the financing and coordination of research efforts of a group of investigators, possibly from several institutions, and is in- tended to concentrate on one particular topic and/or on one maJor area of interest over a period of, as a rule, 5 years. Discussions on the feasibility of a major programme on vertical move- ments started in 1971. The tentative programme was published under the title Terrestrial Vertical Movements in the DFG's planning docu- ment Grauer Plan IV: 1972-1974; p. 152. Deliberations within the Na- tional Committee for the International Geodynamics Project and in the Senate Commission for Joint Research in Earth Sciences (Geokommission) set out the scope of the project and envisaged an investigation of the Rheinische Schild, (i. e. , the Rhenish Massif east and west of the River Rhine). Seventeen geoscientists participated in a round-table dis- cussion on the subject Vertical movements and their causes as exempli- fied in the case of the Rheinische Schild, which took place at Bonn- Bad Godesberg on 8th July 1975. At this meeting the scientific objec- tives came more clearly into focus. A Programme Committee formulated the proposal to be put to the Senate of the DFG.

The contributions in this volume discuss the magnetic structures in the outer atmospheres of active late-type stars, and in particular the various methods available for imaging surface features on these objects. Emphasis has been laid upon multiwavelength studies of the phenomena and the application of solar astrophysics to stellar objects. The book is recommended to research workers or postgraduate students in stellar astrophysics.

This book collects together a selection of the best papers presented at the Third International Bioastronomy Symposium held in 1990. The subject is bioastronomy, the search for life in the universe, andthe book is devided according to the five main stages of life as recognized by this new branch of science: cosmic organic, prebiotic, primitive biological, and advanced. Thereader will find here the most recent results obtained by top specialists from all over the world on hot topics such as the formation and discovery of planets, organic chemistry in meteorites and comets, prebiotic chemistry in the atmosphere of Titan, the search for primitive life in the permafrost of Mars, and, SETI itself, the search for extraterrestrial intelligence. Complemented by live discussions each presentation forms a review of the state-of-the-art treatment of a particular area and also looks toward those developments in bioastronomywhich will surely be realized in the next few years.

Forest fIres are considered a major environmental problem in many European Union Member States as well as in other parts of the world. According to a recent report of the European Commission, forest fues are a dominant feature of the landscapes of the fIve Southern European Member States - Portugal, Spain, France, Italy and Greece, and almost a half of the Community's forests have been classed as fue-risk areas. Protection from forest fues is an interdisciplinary endeavour, which needs to be addressed from both the technological and methodological point of view, and which necessitates a wide spectrum of various scientifIc disciplines. It also implies the solution of numerous practical problems (both of a generic nature and of a specifIc one) and the consideration of the characteristics of the specifIc areas in which fue fIghting is carried out. ScientifIc research is offering a major contribution to forest fIre fIghting. The European Commission (DG XII, Directorate General for Science, Research and Development) has supported since the 1980s a number of multinational research projects through its successive RTD programmes in the fIeld of the Environment.

Distinguished authors discuss topics in physical oceano- graphy, transonic aerodynamics, dynamics of vorticity, numerical simulation of turbulent flows, astrophysical jets, strange attractors, human-powered flight, and thefluid mechanics of the Old Faithful geyser and of the Mount St. Helens eruption of 1980. The authors deal with specific problems, but the emphasis is usually on the way that re- search is carried out at the edge of understanding, and often on the role of new techniques, instruments, and re- search strategies.

The contributions in this volume report recent studies on the sun and late-type stars. Particular emphasis is placed on observations that are relevant to the question of large-scale magnetic activity, and also on the theoretical (dynamo) models for such activity. Experimental papers deal with surface imaging techniques. Explicit computer simulations of hydromagnetic turbulence give insight into the magnetic topology and associated fluid motions, especially near the base of the convection zone. In addition, mean-field dynamo models are presented. The book addresses researchers but should also AEjbe useful for graduate students.

The chemical, physical and physicochemical processes that are at work in the depths of the Earth, both connected and unconnected with man's activities and coupled to the relevant properties and characteristics of the rocks, began to be intensively studied in the early decades of the present century. Until then little evidence had been available concerning the physical and physicochemical properties of rocks, and the data that existed were one-sided and uncoordinated. Both in this country and elsewhere an interest in investigating natural processes, the processes taking place in rocks, and the properties and characteristics of rocks arose as a result of the intensive development of oil and gas engineering, the mining of coal and ore, the construction of large projects, railroads, etc. Information on the properties of rocks was needed, in particular, to facilitate progress in engineering, technology, and geological and geophysical methods of prospecting for extracting and processing mineral deposits. In the late 1920s and early 1930s, methods involving intrinsic and induced pola rization were introduced. Moreover, little information was available concerning the petrophysical and petrochemical quantities characterizing the different contribution of various rocks to electrical processes. Electrical methods were followed by other methods of applied physics based on the novel electrical, thermal, magnetic, nuclear, elastic and other properties of rocks.

Precambrian Crustal Evolution of China integrates the theory of plate tectonics, structural geology and petrology to identify the tectonic and metamorphic environment in different stages of development of the Archaean and Proterozoic crust. Further, the evolution of the Precambrian atmosphere and hydrosphere is approached by using geochemical data and traces of life. For the first time, the results of the study of the Precambrian geology of China are made available in English to scientists and students not having access to the huge amount of Chinese literature.
