Providing a balance between principles and practice, this introduction to geophysical surveying takes readers from the basic physical phenomena, through the acquisition and processing of geophysical data, to the creation of subsurface models and geological interpretation to find hidden ore bodies. Detailed descriptions of the key surveying techniques are given, including gravity, magnetic, radiometric, electrical, electromagnetic and seismic methods, and each technique is presented in a consistent format, using non-mathematical language. The surveying techniques are connected with interpretation topics such as petrophysics, modeling, and the identification of noise in geophysical datasets. Packed with full-color figures which are also available online, the text is richly supported by numerous globally-selected case studies from a range of mineral deposit types. Designed for advanced undergraduate and graduate courses in mining exploration, Geophysics for the Mineral Exploration Geologist is also a valuable reference source for professionals in the mining industry wishing to make greater use of geophysical methods.

Mike Dentith is Professor of Geophysics at the University of Western Australia. He has been an active researcher and teacher of university level applied geophysics and geology for more than 20 years, and he also consults to the minerals industry. Professor Dentith's research interests include geophysical signatures of mineral deposits (about which he has edited two books), petrophysics and terrain scale analysis for exploration targeting using geophysical data. He is a member of the American Geophysical Union, Australian Society of Exploration Geophysicists, Society of Exploration Geophysicists and Geological Society of Australia.
Stephen T. Mudge has worked as an exploration geophysicist in Australia for more than 35 years, and currently works as a consultant in his own company Vector Research. He has worked in many parts of the world and has participated in a number of new mineral discoveries. Mr Mudge has a keen interest in data processing techniques for mineral discovery and has produced several publications reporting new developments. He is a member of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists, Australian Society of Exploration Geophysicists, Society of Exploration Geophysicists and European Association of Engineers and Geoscientists.
"More and more, great ore deposits are being found under cover and knowledge of exploration geophysics provides a distinct advantage in their discovery. Dentith and Mudge provide a clear, comprehensive, up to date, and (very significantly) applied approach for the general geologist, demonstrating how to locate concealed orebodies by employing modern-day geophysical techniques."

"Readers will really appreciate the up-to-date system descriptions, examples and case histories presented [...] In particular, the diagrams in this textbook are superb; the explanatory diagrams have been drawn professionally and the geophysical data and images are shown in full colour."
