Book Description
The outflow of heat from the earth's interior, the terrestrial heat flow, and the temperature field at depth are determined by deep-seated tectonic processes. The knowledge of the re gional heat flow pattern is thus very important in geophysics and provides a useful tool for studying crustal and litho spheric structure and understanding the nature of their evo lution. In order to use the results of heat flow measurements for regional studies and/or to correlate the observed surface geothermal activity with other geophysical or geological fea tures, a map showing the surface distribution of heat flow is necessary. Since 1963, when the first comprehensive listing of all available heat flow data appeared (Lee, 1963), several at tempts have been made to up-date the list, to classify all the data and to interpret them with respect to tectonics, deep structure and to use them for constructing surface heat flow maps. The first listing was subsequently revised by Lee and Uyeda (1965); numerous new data which were published there after were included in successive catalogs compiled by Simmons and Horai (1968) and then again by Jessop et al. (1976). The map showing the surface heat flow pattern may also be of great value for practical purposes, in view of the recent world-wide search for applicable sources of geothermal energy.

Book Description
Deep seismiC sounding was proposed by G. A. Gamburtsev and developed under his guid ance during the period 1948-1955 at the Institute of Physics of the Earth of the Academy of Sciences of the USSR. During that period also, the first geophysical results concerning the deep structure of the earth's crust in several regions in Tien-Shan, the Pamir, and Turkmenia were observed. Beginning with 1956, the deep seismic sounding method has been used widely by geo physical research groups as well as by geophysical service organizations for regional studies in the USSR. Descriptions of this work have been given in reports by Yu. N. Godin, V. V. Fedynskii, D. N. Kazanli, and others. New variants of the deep seismic sounding method have been developed; continuous profiling (Yu. N. Godin, and others), and point soundings (N. N. Puzyrev, and others). Deep seismic soundings have been carried on outside of Russia also, and studies have been carried out on the use of the deep seismic sounding method in marine applications (E. I. Gal'perin, S. M. Zverev, 1. P. Kosminskaya, Yu. P. Neprochnov, and others). OVer the past decade, the deep seismic sounding method has joined the suite of geo physical studies as a highly detailed method for studying the earth's crust and upper mantle to depths of 50 to 100 km on land, and of 15 to 25 km in the deep oceans.

Book Description
"This volume contains a comprehensive, worldwide history of seismological studies of the Earth's crust using controlled sources from 1850 to 2005. Essentially all major seismic projects on land and the most important oceanic projects are covered. The time period 1850 to 1939 is presented as a general synthesis, and from 1940 onward the history and results are presented in separate chapters for each decade, with the material organized by geographical region. Each chapter highlights the major advances achieved during that decade in terms of data acquisition, processing technology, and interpretation methods. For all major seismic projects, the authors provide specific details on field observations, interpreted crustal cross sections, and key references. They conclude with global and continental-scale maps of all field measurements and interpreted Moho contours. An accompanying DVD contains important out-of-print publications and an extensive collection of controlled-source data, location maps, and crustal cross sections."--Publisher's description.

Book Description
The translation is a summary of complex data on the earth's crust and upper mantle. In the examination of the data on the various regions of the terrestrial globe (characteristics of the gravity, magnetic, seismic, thermal and electric fields of the earth) and the comparison between them and the structure of the crust, the author reveals the specific features of the different geological structures and determines the diagnostic significance of the geophysical data. Much attention is given to the crustal structure of the oceanic areas. A description of the general characteristics of the relief and the physical properties of the upper mantle is given in the last section of the book, where the physical map of the upper mantle is given in the last section of the book, where the physical map of the upper mantle is presented. In conclusion, a review is given of the projects of ultradeep scientific boring in the Pacific ocean, territory of the USSR, Japan and Canada. (Author).

Book Description
Treatise on Geophysics: Seismology and Structure of the Earth, Volume 1, provides a comprehensive review of the state of knowledge on the Earths structure and earthquakes. It addresses various aspects of structural seismology and its applications to other fields of Earth sciences. The book is organized into four parts. The first part principally covers theoretical developments and seismic data analysis techniques from the end of the nineteenth century until the present, with the main emphasis on the development of instrumentation and its deployment. The second part reviews the status of knowledge on the structure of the Earths shallow layers, starting with a global review of the Earth's crustal structure. The third part focuses on the Earth's deep structure, divided into its main units: the upper mantle, the transition zone and upper-mantle discontinuities, the D region at the base of the mantle, and the Earth's core. The fourth part comprises two chapters which discuss constraints on Earth structure from fields other than seismology: mineral physics and geodynamics. - Self-contained volume starts with an overview of the subject then explores each topic with in depth detail - Extensive reference lists and cross references with other volumes to facilitate further research - Full-color figures and tables support the text and aid in understanding - Content suited for both the expert and non-expert
