Methods in Computational Physics, Volume 13: Geophysics is a 10-chapter text that focuses with the theoretical solid-earth geophysics. This volume specifically covers the general topics of terrestrial magnetism and electricity, the Earth's gravity field, tidal deformations, dynamics of global spin, spin processing, and convective models for the deep interior. This volume surveys first the construction of mathematical models, such as the representation of the geomagnetic field by assuming arrangements of multipole sources in the core and the fast computer evaluation of two- and three-dimensional gravity models, which revolutionized their use in mineral prospecting and in studies of the crust....
This text bridges the gap between the classic texts on potential theory and modern books on applied geophysics. It opens with an introduction to potential theory, emphasising those aspects particularly important to earth scientists, such as Laplace's equation, Newtonian potential, magnetic and electrostatic fields, and conduction of heat. The theory is then applied to the interpretation of gravity and magnetic anomalies, drawing on examples from modern geophysical literature. Topics explored include regional and global fields, forward modeling, inverse methods, depth-to-source estimation, ideal bodies, analytical continuation, and spectral analysis. The book includes numerous exercises and a variety of computer subroutines written in FORTRAN. Graduate students and researchers in geophysics will find this book essential.
Published by the American Geophysical Union as part of the Geodynamics Series, Volume 1. The focus of the International Geodynamics Project, 1970–1979, was the movements of the surface and upper part of the earth's interior and it was recognized that most of the deformation occurs along narrow belts between the lithospheric plates. Also important to understanding earth process were those motions, primarily vertical that occurred within the plates, remote from plate boundaries. For this reason one of the 10 working groups set up in 1971 was working group 7 with the title "Eperogenic movements of regional extent" under the chairmanship of Dr. J. Tuzo Wilson. In 1974, after Dr. Wilson resigned following his retirement as Principal of Erindale College, University of Toronto, the Bureau of the Inter-Union Commission on Geodynamics appointed Dr. R. I. Walcott as chairman and the name of his working group was changed to "Dynamics of Plate Interiors". The objective of its programme was to determine the nature and origin of the dynamics of the more stable regions of the earth.

" ... as soon as one has traversed the greater part of the wild sea, one comes upon such a huge quantity of ice that nowhere in the whole world has the like been known." "This ice is of a wonderful nature. It lies at times quite still, as one would expect, with openings or large fjords in it; but sometimes its movement is so strong and rapid as to equal that of a ship running before the wind, and it drifts against the wind as often as with it."

This multi-author book has been prepared by an international group of geoscientists that have been active in rift research since the late 1960s. In 1984, an informal, grass-roots study group was initiated to compare individual research results and to explore in greater depth the apparent differences and similarities in the interpretations from various rift systems. The group became known as the CREST working group, an acronym of Continental Rifts: Evolution, Structure and Tectonics, which not surprisingly became the title of this book.Continental Rifts: Evolution, Structure, Tectonics presents an overview of the present state of understanding and knowledge of the processes of continental rif...
