The aim of this course is to provide the basic elements and current concepts to enable students to understand and analyse scientific studies related to these branches of Geology. In addition, at the end of the course, students should be able to write a geological report that is concise, accurate and correct.
The first part of the course details the technique of stereographic projections in order to represent geological structures. The second part of the course focuses on the concepts of stress and strain. The respective markers of stress and strain in rocks are then detailed. Finally, the different fracturing mechanisms of rocks are analysed in the light of the stress representation using the Mohr circle and the Mohr-Coulomb fracture envelope. For the practical work, the students have two days in the field in Rochefort. The first day is devoted to measuring the direction and dip of the layers to calculate the flooding of a fold axis. The second day is devoted to fracture measurements. The data are processed using the "spheristat" software.
Oral exam (synthetic presentation of a Structural Geology and/or Tectonophysics article) + written exam on the practical work.
