To the blessed memory of Valery Kormiltsev…
The Lecture Notes by F. Kamenetsky, G. Trigubovich, and A. Chernyshev provide a detailed review of the principals of electromagnetic exploration methods based on the induced polarization (IP) effect. The development of the theory and applications of the IP method in geophysics has a long and sometimes complicated history. While the discovery of the IP effect can be attributed to Conrad Schlumberger, a separate and ostensibly independent study of the IP phenomenon for mineral exploration was conducted in the second half of the 20th century in the former Soviet Union and in the USA. The uniqueness of these Lecture Notes is that they present in a concise way a summary of the results developed by Russian geophysicists over the last decades and related to the IP method, which until recently were unavailable to the Western readership.
The Lectures begin with the theoretical foundations of electromagnetic methods, describe in detail the phenomenological models of the polarizability of rocks, develop the methods of separating electromagnetic induction and IP effects, and conclude with case studies of the practical application of the IP method in the mining industry. The Lectures also contain an exhaustive reference list of mostly Russian publications on the subject. A number of new results, presented in the Lectures, were developed by the authors themselves. The important message of these Lectures is that the IP phenomenon represents an intrinsic property of the rocks and should be taken into account in practically all geophysical electromagnetic methods.
The presentation of the subject is well organized, starting with simple models of the IP effect and proceeding to more comprehensive theoretical analysis. The Lectures also contain a large number of illustrations providing helpful insight into the physics of the IP phenomenon and its geological application. These Lecture Notes, written by well-known experts in electromagnetic geophysics, represent an important contribution to the field. They will constitute a useful source of information for the study of IP methods by graduate students and researchers. I am pleased to recommend this enlightening book to the electromagnetic geophysical community.Michael S. Zhdanov
