PhD course - Deep mineral prospecting using electromagnetic methods

Thorkild Rasmussen from Luleå University of Technology and Thomas Kalscheuer from Uppsala University will teach a PhD student course on mineral prospecting using electromagnetics called "Electromagnetic methods in deep mineral exploration". The course is held in September and October 2022 and is intended for PhD students in geophysics or Earth sciences with a strong background in physics and mathematics. Teaching will be held on-line on Zoom in blocks of two to three hours, and the total number of contact hours (lectures and in-class exercises) will be about 30.


To register, please send an e-mail to We need the following information to confirm your status as PhD student and to register you:

  • name,
  • date of birth,
  • name of university, institution and country of university you are enroled at for PhD student studies,
  • country of your citizenship,
  • e-mail address,
  • if you are not a PhD student at Uppsala University, we need a scan or a photocopy of your passport and a certificate from your home institution confirming your status as PhD student in fall 2022.

In the Swedish system, the course will be worth 5 ECTS. Participants from other countries will have to negotiate the number of credits with their supervisors. The course will be free of charge, also for international PhD students.


We plan to cover the following topics:

  • Introduction and overview of borehole and surface EM methods:
    • Maxwell’s equations
    • Inductive and galvanic effects
    • Reflection and refraction of plane waves
    • Electric and magnetic properties of rocks including superparamagnetic and induced polarisation effects
    • Controlled sources: magnetic dipoles, electric dipoles and elongated sources
    • Sensors and receiver systems
    • Overview of forward and inverse modelling
  • Overviews of methods including theory, systems, data acquisition, processing and inversion illustrated by case studies on mineral exploration (November 18-20):
    • Geoelectric, induced polarisation, magnetometric resistivity and resistivity logging methods
    • Magnetotelluric and controlled-source audiomagnetotelluric methods
    • Time-domain controlled-source EM methods including live modelling session
    • Georadar methods
    • Loop-loop frequency-domain EM methods

The participants will be continuously assessed in the form of exercises done during and, if needed, after class in groups of three or four students. The groups need to submit these exercises. Successful completion of the course requires more than 50% of the points for the exercises to be scored.
