v. 2. Application, pts. A and B ISBN 9781560800613
内容説明
This second of two volumes covers, in depth, the physical basis of EM methods of exploration magnetometric resistivity, profiling methods using small sources, large-layout harmonic field systems, EM soundings, time-domain EM prospecting methods, VLF, MT, CSAMT, airborne EM methods, borehole EM techniques, and electrical exploration methods for the seafloor. As the first volume focused on theory, this volume focuses on application.

内容説明
This first of two volumes presents mathematical and physical foundations common to all EM methods and has chapters on numerical and analog modeling. The chapters on electrical properties of rocks and resistivity characteristics of geologic targets help readers envisage different kinds of ground structures that may be addressed and the effect of various factors on observed conductivities of rocks. Basic principles of modern instrument design are discussed in the chapter on detection of repetitive EM signals. The last chapter discusses the principles of EM inversion as a first step toward achieving the elusive goal of automatic interpretation of EM data.
