Structural geology

This teaching unit presents the fundamentals of structural geology at master's level. It focuses on the analysis of the various objects and mechanisms of deformation of the Earth's crust from the surface to the base of the crust. Deformation is presented using examples from the field, samples, thin sections, and experiments. These observations are compared with theory and analogical, analytical, and numerical modeling.
Key topics covered:
(1) analysis of deformation at all scales and associated tectonic regimes
(2) typology and kinematics of structural features (e.g., faults, fractures, folds, shear zones),
(3) balanced structural section,
(4) link between different scales and depths of deformation,
(5) different rheological and structural contexts (brittle and ductile structural levels, compressive and extensive regimes, homogeneous and stratified environments),
(6) presence of fluids and their role in deformation.

This course aims to provide students with advanced knowledge, practical skills, and mastery of data acquisition tools in the field, on samples and thin sections for the analysis of brittle and ductile deformation objects and the construction of balanced sections.
