The subject of this book is the methodology and results of integrated geophysical investigations in the Caucasian region, mainly interpretation of magnetic and gravity anomalies with utilization of a huge petrophysical database for the evaluation of geological structure and mineral resources. Relative voluminous geophysical data are useful for the Earth Sciences researchers interested in the Caucasian region (and adjacent and similar regions) characterized by complicated geological structure, inclined magnetization (polarization), uneven topography and mountain/sea transition. Examination of geophysical fields verified by super-deep wells drilling indicates that magmatic rocks of the Lesser Caucasus are extended northward under thick sedimentary cover of the Kura Depression up to the Greater Caucasus. These rocks form hidden petroleum-bearing traps of a newly identified type. On the basis of geophysical studies (mainly inexpensive magnetic and electric methods), a new copper-polymetallic province in the Greater Caucasus has been revealed. a newly developed integrated approach and special information-statistical techniques for processing and interpretation of geophysical data facilitate detection of important geological features, e.g. hidden intersections of linear structures that control location of large commercial ore and oil-and-gas deposits, as well as focuses of dangerous geodynamic events at a depth. Numerous illustrations (including colour) elucidate different problems and solutions on various scales and in diverse geological-geophysical environments. Many aspects of this book have been presented at the teaching courses for bachelors, masters and doctors at the Tel-AvivUniversity (Tel Aviv, Israel) and Ben-Gurion University (Bea (TM)er-Sheva, Israel). Benefits to readers are predetermined by the combination of the authors many-years personal experience in the geophysical studies of Azerbaijan and other regions of the Caucasus with the authora (TM)s knowledge of the modern level of geophysics in the world.

The articles in this volume were selected from a series of reports delivered in the So viet Union at Yaroslavl during the International Seminar "Super-deep drilling and deep geophysical research," which was organized and held in August 1988 by the Ministry of Geology of the USSR, jointly with the Inter-Union Commission on the Lithosphere. One of the most important problems of modem geology, is the state and prospects of further development of deep continental structure investigations, was discussed at the seminar with the participation of 245 scientists and specialists from 19 countries. At the plenary and sectional meetings of the seminar, 83 reports were delivered, discussions on the most interesting problems were organized, the exchange of ideas between the leading scientists a round table took place in discussion. The distinctive feature of the present collection of articles is the wide scope of the investigation of the Earth's crust. The reports elucidate such subjects of world impor tance as (1) achievements in implementation of major scientific programs investi gating deep Earth structure and plans for their further materialization; (2) theoretical problems of carrying out geological-geophysical explorations and drilling operations; and (3) new approaches to the study of the Earth's interior. The results of deep inves tigations of individual countries and organizations are considered, and concrete tech nical elaboration, methods of work execution, etc. are discussed."

Hans Ramberg is working in an area of geology where 60 years are a short, often negligible period of time. This is not so in the lives of men. For us it is a time for evaluating past accomplishments and a time for friends to express their appreciation and admiration. Some universities have become famous for this ability to foster eminent scientists in one or several fields. The success of Cambridge University in physics is a well-known example, but if we ask ourselves whether the success of Oslo University in earth sciences is not equally astonishing, then we see that Hans is yet another example of this process; but it is not the whole story. There were certainly promising prospects when he started his studies in geology: V. M. Goldschmidt had just come back from G6ttingen in Germany and Tom Barth had returned from the Geophysical Laboratory in Washington, D.C. Two leaders in geochemistry and petrology at the same time Hans became a student of Barth, specializing in metamorphic rocks and their problems; but soon the situation changed. Norway was occupied by the Germans and the possibili ties for university studies almost vanished. However, in spite of all difficulties he obtained his Ph.D. in 1946 and began participating in the geological mapping of Greenland. In 1947 he went to the University of Chicago and stayed there until 1961 when he came to his present position in the University of Uppsala, Sweden."

These words are written on the SOOth anniversary of Columbus' discovery of the New World. Surely the deep-space exploration of other worlds in our Solar System over the past few decades is an event of similar magnitude. Man has traveled far enough to see Spaceship Earth suspended alone in black space. And he has voyaged even farther to marvel at the crescent Earth rising over the Moon's cratered terrain. Instrumented spacecraft have toured the entire Solar System even beyond the ninth planet Pluto. This work of science Morphology of the Rocky Members of the Solar System is an inquiry about our extended home. As with the Darwinian and Copernican paradigms, the nature of our planetary system, as the extended world around us, has great significance for those who ponder the human condition. The deep-space views of our Planet Ocean with its sweeping clouds, and moving oceans and creeping continents must rank as the greatest photograph ever taken. Viewing Spaceship Earth hanging in the vast void is an almost frightening experience. We are so alone! It is easy to understand why so many are attracted to a simpler account of origins, like the allegorical tale of creation written in heroic style (but eschewing math, maps, figures, tables, references, and evidence) in the first eleven chapters of Genesis. This treatise examines the morphology of the six rocky planets and their 27 satellites from a broad perspective.

The past two decades have witnessed a revolution in the earth sciences. The quantitative, instrument-based measurements and physical models of. geophysics, together with advances in technology, have radically transformed the way in which the Earth, and especially its crust, is described. The study of the magnetism of the rocks of the Earth's crust has played a major part in this transformation. Rocks, or more specifically their constituent magnetic minerals, can be regarded as a measuring instrument provided by nature, which can be employed in the service of the earth sciences. Thus magnetic minerals are a recording magnetometer; a goniometer or protractor, recording the directions of flows, fields and forces; a clock; a recording thermometer; a position recorder; astrain gauge; an instrument for geo logical surveying; a tracer in climatology and hydrology; a tool in petrology. No instrument is linear, or free from noise and systematic errors, and the performance of nature's instrument must be assessed and certified. This has been the task of the research worker in rock and mineral magnetism."

This series of monographs represents continuation on an inter national basis of the previous series MINERALOGIE UND PETRO GRAPHIE IN EINZELDARSTELLUNGEN, published by Springer Verlag. The voluminous results arising from recent progress in pure and applied research increase the need for authoritative reviews but the standard scientific journals are unable to provide the space for them. By their very nature, text-books are unable to consider specific topics in depth and recent research methods and results often receive only cursory treatment. Advanced reference volumes are usually too detailed except for experts in the field. It is often very expensive to purchase a symposium volume or an "Advances in . . . " for the sake of a specific review chapter surrounded by volume unrelated chapters. We hope that this monograph series will by pass these problems in fulfilling the need. The purpose of the series is to publish reviews and reports of carefully selected topics written by carefully selected authors, who are both good writers and experts in their scientific field. In general, the monographs will be concerned with the most recent research methods and results. The editors hope that the monographs will serve several functions, acting as supplements to existing text-books, guiding research workers, and providing the basis for advanced seminars. W.

Deep-sea manganese nodules, once an obscure scientific curios ity, have, in the brief span of two decades, become a potential mineral resource of major importance. Nodules that cover the sea floor of the tropical North Pacific may represent a vast ore de posit of manganese, nickel, cobalt, and copper. Modern technology has apparently surmounted the incredible problem of recovering nodules in water depths of 5000 meters and the extraction of metals from the complex chemical nodule matrix is a reality. Both the recovery and the extraction appear to be economically feasible. Exploitation of this resource is, however, hindered more by the lack of an international legal structure allowing for recognition of mining sites and exploitation rights, than by any other factor. Often, when a mineral deposit becomes identified as an ex ploitable resource, scientific study burgeons. Interest in the nature and genesis of the deposit increases and much is learned from large scale exploration. The case is self evident for petrol eum and ore deposits on land. The study of manganese nodules is just now entering this phase. What was the esoteric field of a few scientists has become the subject of active exploration and research by most of the industrialized nations. Unfortunately for our general understanding of manganese nodules, exploration results remain largely proprietary. However, scientific study has greatly increased and the results are becoming widely available."

The Eighty-Second National Meeting of the American Institute of Chemical Engineers, held in Atlantic City, New Jersey, from August 29 through September 1, 1976, had as one of its themes the topic of transport processes. One of the sessions related to this theme was "Transport Processes in the Oceans" chaired by R. P. Shaw and R. J. Gibbs. This session was devoted to the study of transport processes and their hydrodynamic modeling in large water bodies such as oceans and lakes; transport of both dissolved and solid material was con sidered. The interest developed at the session led to the conclu sion that the papers presented there should be published as a set rather than dispersed among the various technical journals that rep resent the wide variety of technical affiliations of the authors. This variety, in fact, is typical of this particular field with con tributors identified as chemical engineers, civil engineers, environ mental engineers, mechanical engineers, oceanographers and applied mechanicians to name just a few. Such an interdisciplinary area re quires more effort in keeping abreast of developments than do the traditional areas, since new material may be developed and presented in a wide range of technical journals and professional meetings."

An atmospheric phenomenon is considered as 'explained' when we have succeeded in deducing it on the basis of accepted principles of physics. (H. Ertel, Methods and problems of dynamical meteorolo gy,p. l) Until recently, noctilucent clouds were regarded merely as a curious atmos pheric phenomenon, the occurrence of which aroused only limited scientific attention. However, in the last two decades the interest they have been given has markedly increased. The clouds, usually pale blue in colour, may be seen on a clear night at high latitudes. Typical examples are illustrated in the book. Clouds looking like these in daytime would be classified as cirrostratus. What sets noctilucent clouds apart is their occurrence in the middle of the night, their very obvious pale blue colour, and their disappearance into the dawn close to the onset of civil twilight when the Sun is 6 Degrees below the horizon. as being set apart from ordinary Noctilucent clouds were first recognized clouds in 1884/1885 and in a series of sightings that followed their return in the summer of 1885. That year marked the beginning of observations and the interpretation of twilight phenomena. The impetus came from the extraordi nary Krakatoa eruption, which was not only one of the most spectacular volcanic eruptions in recorded history, but which also turned out to be a startling event in atmospheric science with repercussions even in our time.

This monograph was begun with two objectives in mind. The first was to provide a review of research involving the application of neodymium isotopic measurements to pro blems in earth science. In the process of organizing to do this, I realized that the research in this field had produced a need for an updated review of the underlying paradigms. This need had arisen because of the special properties of the samarium-neodymium isotopic system, and because the research had transgressed the traditional boundaries be tween the subfields of earth science. Without such a review, the significance of the results seemed likely to remain un necessarily obscure to interested scientists from related disciplines. Consequently, the second objective became the provision of a theoretical framework for the application of neodymium isotopic studies. Much of what this contains is not new, but it is drawn together here for the first time. At the time the writing was initiated, the literature of the field was still relatively limited. Over the past 5 years it has grown enormously. Considering the rate at which the writing progressed, it became clear that this could not be a fully up-to-date review and still reach completion. The selection of material for the review sections is biased toward earlier studies. Part I presents most of the background information."

Terrestrial mass movements (i.e. cliff collapses, soil creeps, mudflows, landslides etc.) are severe forms of natural disasters mostly occurring in mountainous terrain, which is subjected to specific geological, geomorphological and climatological conditions, as well as to human activities. It is a challenging task to accurately define the position, type and activity of mass movements for the purpose of creating inventory records and potential vulnerability maps. Remote sensing techniques, in combination with Geographic Information System tools, allow state-of-the-art investigation of the degree of potential mass movements and modeling surface processes for hazard and risk mapping. Similarly, through statistical prediction models, future mass-movement-prone areas can be identified and damages can to a certain extent be minimized. Issues of scale and selection of morphological attributes for the scientific analysis of mass movements call for new developments in data modeling and spatio-temporal GIS analysis.
The book is a product of a cooperation between the editors and several contributing authors, addressing current issues and recent developments in GI technology and mass movements research. Its fundamental treatment of this technology includes data modeling, topography, geology, geomorphology, remote sensing, artificial neural networks, binomial regression, fuzzy logic, spatial statistics and analysis, and scientific visualization. Both theoretical and practical issues are addressed.

In Plants and the K-T Boundary, two of the world's leading experts in palynology and paleobotany provide a comprehensive account of the fate of land plants during the 'great extinction' about 65 million years ago. They describe how the time boundary between the Cretaceous and Paleogene Periods (the K-T boundary) is recognized in the geological record, and how fossil plants can be used to understand global events of that time. There are case studies from over 100 localities around the world, including North America, China, Russia and New Zealand. The book concludes with an evaluation of possible causes of the K-T boundary event and its effects on floras of the past and present. This book is written for researchers and students in paleontology, botany, geology and Earth history, and everyone who has been following the course of the extinction debate and the K-T boundary paradigm shift.

Human development is a long and steady process that began with stone tool making. Because of this skill, humans were able to adapt to climate changes, discover new territories, and invent new technologies. "Pressure knapping" is the common term for one method of creating stone tools, where a larger device or blade specifically made for this purpose is use to press out the stone tool. Pressure knapping was invented in different locations and at different points in time, representing the adoption of the Neolithic way of life in the Old world.

Recent research on pressure knapping has led for the first time to a global thesis on this technique. The contributors to this seminal work combine research findings on pressure knapping from different cultures around the globe to develope a cohesive theory. This contributions to this volume represents a significant development to research on pressure knapping, as well as the field of lithic studies in general.

This work will be an important reference for anyone studying the Paleolithic, Mesolithic, and Neolithic periods, lithic studies, technologies, and more generally, cultural transmission.

The Second Volume of Equilibrium between Phases of Matter, when compared with the First Volume, by H.A.J. Oonk and M.T. Calvet, published in 2008, amounts to an extension of subjects, and a deepening of understanding. In the first three sections of the text an extension is given of the theory on isobaric binary systems. The fourth section gives an account of the thermodynamic analyses of four isobaric binary key systems, highlighting the power of empirical, (exo)thermodynamic correlations. The fifth section is devoted to the thermodynamic description of ternary systems. The last three sections concentrate on the properties of materials, and the phase behaviour of systems under the conditions of high temperature and high pressure conditions that prevail in the interior of the Earth. A new equation of state is the subject of the sixth section. In the seventh section a move is made to statistical thermodynamics and vibrational models; the description of the systems has changed from mathematical to physical. The last section is on the system MgO SiO2, looked upon from a geophysical point of view.

Throughout the work high priority is given to the thermodynamic assessment of experimental data; numerous end-of-section exercises and their solutions are included. Along with the First Volume, the work is useful for materials scientists and geophysicists as a reference text.

Volume II is a lecture book for postgraduate students in chemistry, chemical engineering, geology and metallurgy. It is highly useful as a recommended text for teachers and researchers in all fields of materials science.

Cratons and Fold Belts of India, is a unique attempt at presenting geological characteristics and evolution of the fold belts and the cratonic areas of the Indian shield. The author has evaluated the different evolutionary models for each fold belt in light of all the currently available geological and geochronological informations that are clearly listed. Shortcomings, if any, of each model are stated and a viable geodynamic model is presented for each fold belt. The book is self-contained it includes an introduction to the processes of mountain building, especially plate tectonics theory with its application to the evolution of the Himalaya as an illustrative example so that the reader can better appreciate the novel approach to the evolution of Proterozoic fold belts. The author eschews a detailed account of the fold belts for a clear description of all the concepts that go into building models. It is primarily written for graduate students, teachers and for those geoscientists who aspire to know all about the Indian shield."

Drilling deep into the earth holds a fascination for earth scientists derived in part from the fact that the drill hole is the ultimate test of a hypothesis. When surface exploration methods have been fully uti lized and all the geological inferences drawn about the structure be neath the surface, we must finally drill to sample directly the third dimension of the crust of the earth. The drill is thus the tool of choice of the energy and minerals re sources industry. Because of high cost, drilling has been only sparing ly used for solving fundamental problems in the earth sciences. But now, having used the quite sophisticated methodology of exploration geophysics, the exciting structural detail emerging from seismic re flection profiling in particular has led several nations to begin a major program of scientific drilling to solve some of the major prGb lems in the earth sciences. Hhat is described in this volume are the blueprints for national re search programs in France, the Federal Republic of Germany, Japan and the United States. The Soviet Union has already embarked on a major drilling effort, the results of which are soon to be published. Results, of course, are still few, and this first volume is more concerned with the problems to be solved."

This book presents a new method for solving geomechanical problems - one that explicitly takes into account deformation and fractures of soils, which create important effects, but are neglected in classical approaches. The method reveals the influence of the form of a structure on its ultimate state. The entire approach takes into account five types of physical as well as geometrical non-linearity, and highlights the simplicity of some non-linear computations against the consequently linear ones.

The determination of crustal structure by means of explo sion seismology has been one of the major objectives of the European Seismological Commission (ESC) over the past twenty-five years. It was decided some time ago to publish the results of regional crustal investigations in Europe in a series of monographs. This publication entitled "Ex plosion Seismology in Central Europe - Data and Results" is Volume 1 in a sequence of publications dealing with the crustal structure in Europe. The European seismologists are indebted to the German Geo physical Society (Deutsche Geophysikalische Gesellschaft) for taking the initiative to publish this book. Thanks are due to the German Research Society (Deutsche Forschungs gemeinschaft) for providing generous financial support of the field measurements and data evaluation. It is hoped that this publication will stimulate a continuation of in vestigations of the earth's lithosphere in order to eluci date the details which are still not fully understood."

Anyone studying the geology and tectonics of China and who is not able to read Chinese will need to have a copy of this book: Ceotectonic Evolution of China and a companion copy of the Tectonic Map of China, scale 1:4000,000. Professor Huang Jiqing and his collaborators from the Institute of Geology, Chinese Academy of Geological Sciences have provided the English-speaking earth scientists with an extremely valuable tool that can be used towards understanding the geo b;;y of China. The introductory chapter is necessary to read prior to effective use of the material discussed in other chapters as it clearly presents the philosophy of this school of tectonics. The collaborators of the book acknowledge the important changes have been brough about by the plate tectonics theory but do not fully incorporate these ideas into their discussion. The book and map are testimony to the tremendous amount of geologic work accomplished by Chinese geologists in the past fourty years. As our Chinese collea gues begin to publish more English summaries such as this, it will become apparent to the rest of the world the vast amount of geologic mapping along with supportive stratigraphy and geophysics that has already been accomplished. Nearly all major non Chinese tracts on tectonic synthesis of the world treat China in only a cursory fashio)1 because so little is known of the area. With this text and map, future world tectonic synthesis can no longer afford to leave China out of the picture."

The Second International Symposium on Observation of the Continental Crust Through Drilling (supported by the Alfred Wegener Foundation, the Federal Ministry of Research and Technology, the German Research Society and the Inter-Union Commission on the Lithosphere) took place in Seeheim (Odenwald) and included a discussion on the Continental Deep Drilling Programme of the Federal Republic of Germany. This sym- posium was regarded as the continuation of a course agreed upon in Tarrytown in 1984. Here, the scientific contents and technical con- cepts of the technically complex and expensive experiments of conti- nental drillings were carefully coordinated before the national commit- tees carne to practical decisions. In Seeheim, rather than in Tarrytown, the methods of technical realization were in the foreground, as the results of scientific projects, e. g. , the NAGRA or the Salton Sea Scien* tific Drilling Project, were evaluated, supplementing industrial ultra- deep drilling experience. The presentation and discussion of the Con- tinental Deep Drilling Project of the Federal Republic of Germany was also granted ample scope with nine lectures and sixty posters. The con- tents of the KTB presentation have been summed up in two contributions and included in this volume. The conference centered on three major subjects: The National- Prograrrunes and Aspects of Geoscience: H. Vidal, FRG; H. Riesen- huber, FRG; E. Seibold, FRG; K. Fuchs, FRG; Cl. Megnien, F; R. S. An- drews, USA; F. G. Stehli, USA; E. A. Kozlovsky, USSR; E. V.

By the year 2000, the number of people at risk from volcanic hazards is likely to increase to around half a billion. Since 1980, significant advances have been made in volcano monitoring, the data from which provides the sole scientific basis for eruption prediction. Here, internationally renowned and highly experienced specialists provide 25 comprehensive articles covering a wide range of related topics: monitoring techniques and data analysis; modelling of monitoring data and eruptive phenomena; volcanic hazards and risk assessment; and volcanic emergency management. Selected case histories of recent volcanic disasters, such as Mount Pinatubo in the Philippines, demonstrate that effective communication - between scientists, civil authorities, the media and the population at risk - is essential to reducing the danger.

This book gives the geological history of the river Nile since it started to excavate its course in the Egyptian plateaus in late Miocene time in response to the lowering sea level of the desic cating Mediterranean. It formed a canyon longer, deeper, and just as awe inspiring as the Grand Canyon, Arizona. The canyon was transgressed by the advancing Mediterranean as it started filling during the early Pliocene, and since then by a number of rivers which ebbed and flowed as they succeeded one another. The modern Nile is a recent and humble successor to mighty rivers which once occupied the Nile Valley. Dallas, Texas Rushdi Said August 1981 Acknowledgments This book is based on field work carried out in Egypt during the seasons 1961-1978 while the author was a member of the Com bined Prehistoric Expedition sponsored by Southern Methodist University, the Polish Academy of Science, and the Geological Survey of Egypt.

Rockglaciers are the visible expression of the creep of mountain permafrost. They are indicative of special geo-ecologic and geomorphic conditions regarding thermal situation, talus production, hydrology, and hazards in high mountain environments of all major mountain systems on earth. As relict features, they are of great paleoclimatic value. This book presents a systematic treatment of this landform in its environmental context.

The Sonderforschungsbereich (SFB) 48-Gottingen, a Special Collaborative Programme of the Deutsche Forschungsgemeinschaft, was one of the first of such programmes. It was launched in 1969 under the general title "Evolution, composition and distinctive characteristics of the Earth's crus t, particularly in geosynclinal regions" ("En twickl ung, Bestand und Eigenschaften der Erdkruste, insbesondere der Geosynklinalraume"). Its activities were promoted for eleven and a half years and it came to its end at the expiration of 1980. We have he re a comprehensive report of the results it has reached, of the questions that remain open, and the new questions that have been raised. Special Collaborative Programmes ("Sonderforschungsbereiche") involve groups of scientists who have join- ed together with the approval of their university for joint research in which the university recognizes that their research has common ground deserving support for a longer period of time. Significant progress in science is increasingly dependent on the close collaboration of scientists from several disciplines. The Special Colla- borative Programmes were created in order to provide better conditions and structures for multi- nad interdisciplinary research. It seemed prom- ising to mount special support, in terms of both material and personnei, for the geologically orientated research programme proposed from Gottin- gen, which envisaged interdisciplinary research into the nature of two different intracontinental orogens, research involving Geology-palaeon- tology, Sedimentology, Sedimentary Petrography, Geochemistry, Petrology, Geochronology and Geophysics.
