Book Description
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.

Book Description
DEKORP, the German continental reflection seismic program, was the major focus of deep seismic research in Germany in the 1980s and 1990s. The seismic sections provided fundamental new insight into deep geological structure of the European continent and the dynamics of continental formation. They formed the basis for worldwide comparative studies of orogenic structure. The complicated signature of the reflections from the deep crust indicated that new processing and interpretation techniques must be considered to better image the crystalline crust. Results of these efforts, including pre-stack migration, 3-D imaging, shear waves and seismic anisotropy, are presented in this special volume. In part, the articles open the perspective to new and future research. In part, they document research activity triggered by technical and interpretational questions raised by DEKORP field work and profiling results. Many of the presented methods can find immediate application in industrial seismic prospecting.

Book Description
600 km giving insight into the 3D structure of the upper mantle. These data are confronted with the requirements of the CTBT for 3D regional seismic models of the lithosphere-asthenosphere system. The two primary purposes of the present work are, first, to present these seismic observations on super long-range profiles in digitised format, using peaceful nuclear explosions (PNE) in the former USSR, and, second, to present the joint thoughts of experts from the deep seismic sounding (DSS) and the comprehensive test ban treaty (CTBT) communities. Implications for petrological and other earth science disciplines are presented. Audience: The CTBT community and earth scientists interested in the 3D structure of the lithosphere-asthenosphere system.

Book Description
Variations in seismic Q are sensitive to a much greater extent than are seismic velocity variations on factors such as temperature, fluid content, and the movement of solid state defects in the earth. For that reason an understanding of Q and its variation with position in the earth and with time should provide information in earth's tectonic evolution, as well as on aspects of its internal structure. Progress in understanding Q has suffered from difficulty in obtaining reliable amplitude data at global and temporary stations. Moreover, laboratory determinations of Q, until recently, were most often made at frequencies much higher than those measured by seismologists for waves propagating through the earth. Recent advances in seismic station distribution and quality, as well as in methodology at both high and low fequencies, have greatly improved the quality of observational data available to seismologists from global stations. Concurrent advances have been made in measuring Q using laboratory samples at frequencies that pertain to the earth and in theoretical understanding of seismic wave attenuation. Papers of this volume present new information on Q in the earth from several perspectives: methodology, results from global and regional observations of both body and surface waves, laboratory measurements, and theoretical understanding. The editors believe that we have reached a new threshold in Q studies and that advances in data quality and methodology will spur increased interest in this difficult, but interesting field.

Book Description
The past few decades have witnessed the growth of the Earth Sciences in the pursuit of knowledge and understanding of the planet that we live on. This development addresses the challenging endeavor to enrich human lives with the bounties of Nature as well as to preserve the planet for the generations to come. Solid Earth Geophysics aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics and forms the intrinsic framework, which other allied disciplines utilize for more specific investigations. The first edition of the Encyclopedia of Solid Earth Geophysics was published in 1989 by Van Nostrand Reinhold publishing company. More than two decades later, this new volume, edited by Prof. Harsh K. Gupta, represents a thoroughly revised and expanded reference work. It brings together more than 200 articles covering established and new concepts of Geophysics across the various sub-disciplines such as Gravity, Geodesy, Geomagnetism, Seismology, Seismics, Deep Earth Processes, Plate Tectonics, Thermal Domains, Computational Methods, etc. in a systematic and consistent format and standard. It is an authoritative and current reference source with extraordinary width of scope. It draws its unique strength from the expert contributions of editors and authors across the globe. It is designed to serve as a valuable and cherished source of information for current and future generations of professionals.
