To provide a strong theoretical grounding in advanced aspects of structural geology, as well as the practical application of structural field mapping techniques in complexly deformed areas.
To understand the theoretical basis and be able to practically apply methods of strain and kinematic analysis, to understand the development of mechanical instabilities such as folds in deformed rocks, and to have a basis for understanding the flow of polymineralic rocks with stronger clasts in a weaker matrix. The aim is to have a strong theretical basis for critically assessing and interpreting field observations.
The first half of the course consist of lectures and practical exercises in more advanced aspects of structural geology, including finite strain theory, finite strain measurement, kinematics, mechanical instability (e.g. folds and boudins), the behaviour of rigid particles in flow, perturbation flow, flanking structures, strain localization and fluid-rock interaction. The second half of the course is a 5-day field mapping exercise in a complexly deformed terrain, with the production of a map and a ca. 10-15 page report. The mark from the written exam at the end of the theory part and the mark for the field report are equally weighted in determining the final result.
A comprehensive script and set of exercises is provided as part of the course.
