Fundamentals of Geophysics, the Earth in the Universe, Its Material Composition, and Its Internal Structure

This book discusses how—by analysis of the physical fields and processes within and on the Earth—we learn how old the Earth is, what are its internal structure and shape, and what are the causes and properties of its magnetic and temperature fields. In contrast, the geophysical survey methods for characterizing the upper crust which are used to explore for mineral ore deposits and hydrocarbon reservoirs are not treated in this book; specialized textbooks should be consulted for these.
