A Student's Guide to Geophysical Equations
The advent of accessible student computing packages has meant that geophysics students can now easily manipulate datasets and gain first-hand modeling experienceessential in developing an intuitive understanding of the physics of the Earth. Yet to gain a more in-depth understanding of the physical theory, and to be able to develop new models and solutions, it is necessary to be able to derive the relevant equations from first principles. This compact, handy book fills a gap left by most modern geophysics textbooks, which generally do not have space to derive all of the important formulae, showing the intermediate steps. This guide presents full derivations for the classical equations of gravitation, gravity, tides, Earth rotation, heat, geomagnetism, and foundational seismology, illustrated with simple schematic diagrams. It supports students through the successive steps and explains the logical sequence of a derivationfacilitating self-study and helping students to tackle homework exercises and prepare for exams. william lowrie was born in Hawick, Scotland, and attended the University of Edinburgh, where he graduated in 1960 with first-class honors in physics. He achieved a masters degree in geophysics at the University of Toronto and, in 1967, a doctorate at the University of Pittsburgh. After two years in the research laboratory of Gulf Oil Company he became a researcher at the Lamont-Doherty Geological Observatory of Columbia University. In 1974 he was elected professor of geophysics at the ETH Zürich (Swiss Federal Institute of Technology in Zurich), Switzerland, where he taught and researched until retirement in 2004. His research in rock magnetism and paleomagnetism consisted of deducing the Earth's magnetic field in the geological past from the magnetizations of dated rocks. The results were applied to the solution of geologic-tectonic problems, and to analysis of the polarity history of the geomagnetic field. Professor Lowrie has authored 135 scientific articles and a second edition of his acclaimed 1997 textbook Fundamentals of Geophysics was published in 2007. He has been President of the European Union of Geosciences and Section President and Council member of the American Geophysical Union (2000-2). He is a Fellow of the American Geophysical Union and a Member of the Academia Europaea.

Special issue Geodynamics of the Latin American Pacific Margin.-- 4 pagesThe Latin American Pacific margin from the Californias to the tip of Tierra del Fuego shares a common geodynamic heritage; the geologic sculptures of this heritage have been chiseled out in large part by the geodynamic processes associated with the subduction of oceanic lithosphere beneath the continental margins.

Solving problems is an indispensable exercise for mastering the theory underlying the various branches of geophysics. Without this practice, students often find it hard to understand and relate theoretical concepts to their application in real-world situations. This book is a collection of nearly 200 problems in geophysics, which are solved in detail showing each step of their solution, the equations used and the assumptions made. Simple figures are also included to help students understand how to reduce a problem to its key elements. The book begins with an introduction to the equations most commonly used in solving geophysical problems. The subsequent four chapters then present a series of exercises for each of the main, classical areas of geophysicsgravity, geomagnetism, seismology and heat flow and geochronology. For each topic there are problems with different degrees of difficulty, from simple exercises that can be used in the most elementary courses, to more complex problems suitable for graduate-level students. This handy book is the ideal adjunct to core course textbooks on geophysical theory. It is a convenient source of additional homework and exam questions for instructors, and provides students with step-by-step examples that can be used as a practice or revision aid. Elisa Buforn is a Professor of geophysics at the Universidad Complutense de Madrid (UCM) where she teaches courses on geophysics, seismology, physics, and numerical methods. Professor Buforn's research focuses on source fracture processes, seismicity, and seismotectonics, and she is Editor in Chief of Física de la Tierra and on the Editorial Board of the Journal of Seismology. Carmen Pro is an Associate Professor at the University of Extremadura, Spain, where she has taught geophysics and astronomy for over 20 years. She has participated in several geophysical research projects and is involved in college management. Agustín Udías is an Emeritus Professor at UCM and is the author of a large number of papers about seismicity, seismotectonics, and the physics of seismic sources, as well as the textbook Principles of Seismology (Cambridge University Press, 1999). He has held positions as Editor in Chief of Física de la Tierra and the Journal of Seismology and as Vice President of the European Seismological Commission.
I II CHAPTER THEORETICAL BASIS OF THE APPLIED GEOPHYSICAL TECHNIQUES
Geophysics can briefly be described as investigation methods that aim towards investigating the earth's physical characteristics as e.g density, electrical conductivity, and elastic properties, which can then be developed into geological models. Contrary to sampling, geophysical measurements may provide a continuous cross section of the sub-surface. On the other hand the interpretation of geophysics to geological and hydrological information is seldom one-sided. The non-uniquess of the result is most often reduced by using a combination of several geophysical methods (Aaltonen, 2000). This chapter deals with the geoelectric resistivity tools and Ground Penetrating Radar (GPR)which we used it at a New Cairo City. The electric resistivity technique is based essentially on the quantitative estimation of the conductivity properties of the subsurface, while the Ground Penetrating Radar (GPR) is a high-resolution technique of imaging shallow soil and ground structures using electromagnetic waves(EM).
