Electromagnetic Sounding of the Earth’s Interior 2nd edition provides a comprehensive up-to-date collection of contributions, covering methodological, computational and practical aspects of Electromagnetic sounding of the Earth by different techniques at global, regional and local scales. Moreover, it contains new developments such as the concept of self-consistent tasks of geophysics, 3-D interpretation of the TEM sounding data and indirect EM geothermometry, which, so far, have not all been covered by one book.
Electromagnetic Sounding of the Earth’s Interior 2nd edition consists of three parts: I- EM sounding methods, II- Forward modelling and inversion techniques, and III – Data processing, analysis, modelling and interpretation. The new edition includes brand new chapters on Pulse and frequency electromagnetic sounding for hydrocarbon offshore exploration and Indirect temperature estimation using EM sounding data additionally all other chapters have been extensively updated to include new developments.
Presents recently developed methodological findings of the earth’s study, including seismoelectrical and renewed magnetovariational approaches
Provides methodological guidelines for Electromagnetic data interpretation in various geological environments
Contains a balanced set of lectures covering all aspects of Electromagnetic sounding at global, regional and local levels along with case studies, highlighting the practical importance of electromagnetic data
Updates current findings in the field, in particular MT, magnetovariational and seismo-electrical methods and the practice of 3D interpretations
