M1 - Geodynamics and Geomaterials

This teaching unit introduces the fundamentals of structural geology at Master's level. It covers the analysis of the various objects and mechanisms of deformation in the Earth's crust, from the surface to the base of the crust. Deformation is presented using field examples, samples, thin sections and experiments. These observations are compared with theory and analog, analytical and numerical modeling.
Key points covered:
(1) analysis of deformation at all scales, and associated tectonic regimes
(2) typology and kinematics of structural objects (eg: faults, fractures, folds, shear zones),
(3) balanced structural cross-section,
(4) links 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.

The aim of this module is to provide a basic understanding of geophysical imaging of geological formations, both near-surface and on a lithospheric scale. The focus is on seismic methods (volume and surface wave tomography, receiver functions, ambient noise), gravimetry and magnetotellurics. We will also present the basics of seismic reflection (acquisition and processing). A practical case study will highlight the importance of combining these methods to provide the best possible description of the environment and its properties, particularly in terms of fluids.

This field placement comes at the beginning of our Master's program. Its aim is to characterize the succession of formation and dismantling processes of the Variscan orogen, through a thematic study of the Montagne Noire massif. Particular attention will be paid to (1) the study of the deformation of the sedimentary cover and the geodynamic evolution of the basins; (2) the analysis of ductile deformation and associated metamorphism in the deepest crustal levels; and (3) the study of late-orogenic basins. This teaching unit is made up of three successive stages: the preparation phase based on the study of cartographic documents in the classroom, field work and the drafting of a report, and finally a critical study of the bibliography.

The aim of this course is to harmonize the knowledge of students from different backgrounds. The course focuses in particular on mineralogy, magmatic petrology and associated metal deposits. These disciplines are approached with a synthetic and global approach, integrating processes and linking the main mineralogical and geochemical reservoirs. The course is supported by practical work in magmatic petrology and metallogeny, involving the study of macroscopic and microscopic rock and mineral samples.

This course presents the mechanical behavior of rocks, based on the results of laboratory-scale work. The different types of laboratory experiments are described, and the various mechanical behaviors are discussed and illustrated with experimental data. Hydrostatic, uniaxial and triaxial compression tests are described. Elastic, plastic and viscous behaviors are considered, and the combination of these behaviors is applied to the description of rock behavior.
Notions relating to the behavior of discontinuities and fracture mechanics are addressed. The notions of creep and deferred behavior will also be covered, in order to consider the long-term behavior of rock masses.
In order to consider mechanical behavior quantitatively, the notions of stress and strain tensors will be covered. These will be used to introduce elastic deformation calculations based on elastic moduli. The calculation of stresses on planes, based on knowledge of the stress tensor, will be covered in the general case and illustrated by Mohr's representation.
