Course Aim

After completed course, the student is expected to be able to:
• explain and apply fundamental principles of geophysical data inversion
• explain basic principles (physics, measuring techniques, data processing and interpretation) for the geophysical methods treated in the course
• explain strength and weakness of geophysical methods
• interpret geophysical data into a geological context
• explain and apply processing techniques for potential field data
• explain and apply the concepts of convolution, Fourier transformation and filtering, explain the • significance of data sampling and the concept of aliasing


Contents
Inversion of geophysical data: Characterization of data and data errors. What are the characteristics of a good model? Model parameterization and Tikhonov regularization. Forward responses and Fréchet derivatives. Solving linear and non-linear inverse problems. Relation between data errors and errors on model parameters. Trade-off between resolution and parameter errors. Á priori data. Monte Carlo inversion. Examples with inversion of various types of geophysical data. Applications in mineral explorations and environmental investigations. Seismic: Data processing and interpretation. Ground penetrating radar: Data processing and interpretation. Potential field data: Source parameter imaging and Euler deconvolution. Equivalent sources. Modelling of complex geological structures.  Physical properties of rocks: Estimation of physical properties of rocks in the laboratory and the link to geological composition.

Realization
The teaching will be as lectures and laboratory training. The lectures will be focused on basic theory and applications on geophysical data. The laboratory part will be on application of the theory.

Examination
Written laboratory report. Written examination with differentiated degrees will be arranged at the end of the teaching period. The examination will include theory as well as practical problem solving. Students who have failed an examination on five occasions will not be allowed further resits.

Remarks
O7008K is equivalent to KGG004 and cannot be combined.
