Entry requirements

180 credits including 1) 75 credits in physics and mathematics alternatively 2) 45 credits in geosciences, 15 credits in physics or mathematics and either Exploration and Environmental Geophysics or both Geophysical Methods with Applications and Statistic Methods in Earth Science. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

On completion of the course, the student should be able to:

• derive the differential equations governing electromagnetic (EM) induction in the Earth starting from Maxwell's equations,
• describe the electric and magnetic properties of various minerals, rock units and ore deposits,
• analyse how current systems excited by galvanically and inductively coupled sources help resolving electrically resistive and conductive targets,
• for a variety of electromagnetic methods, explain the principles, the associated instrument setups at the surface and in boreholes, suitable geological targets, basic data processing steps and evaluation of data quality,
• design field measurements to study a given geological target with a combination of electromagnetic methods that is optimal with regard to depth penetration and resolution.

Content

Electromagnetic theory. Electrical and magnetic properties of rocks. Instruments and sensors. Forward and inverse modelling. Principles, targets, data acquisition, instrument systems, processing, modelling and case studies of the following methods: electrical resistance tomography, induced polarisation, magnetometric resistivity, magnetotellurics, controlled-source audiomagnetotellurics, transient electromagnetics, frequency-domain electromagnetics and ground penetrating radar. Categorisation of EM methods.

Instruction

Lectures, homework, problem solving.

Assessment

Assignments and programming assignments. 

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
