Applied Geophysics in the Search for Minerals

For many years, this book was the standard textbook on applied geophysics. It first appeared in 1928. This 1954 fourth edition was completely revised by Professor Keys to take into account additional developments. Examples of typical aerial survey instruments, gravimeters and seismic reflexion methods are included, and special attention is given to methods of locating radioactive ores. Some extra problems are also added.
