• Sommario/riassunto: In this book the author presents state-of-the-art geophysical electromagnetic (EM) theory and methods of EM geophysics. The book brings together fundamental theory of EM field and practical aspects of EM exploration for mineral and energy resources. The book is divided in four parts covering the foundations of the field theory and its applications to the applied electromagnetic geophysics, including new emerging methods of the marine EM exploration. The first part is an introduction to the field theory required for understanding the basics of geophysical electromagnetic theory. The second
