Geodynamics

This course aims to review and supplement knowledge of fundamental concepts concerning the formation of the oceanic crust and its relationship with magnetism and hydrothermalism, the origin, functioning, and dynamics of subduction zones (formation of active margins and back-arc basins), the mechanisms of subduction and continental collision (formation of the orogenic prism, post-orogenic extension, and exhumation). The links between tectonics and surface processes will also be discussed.

These concepts will be supported by theoretical and physical models, extensively illustrated by natural case studies (Himalayas-Tibet, Taiwan, Alps, Western Pacific, Sumatra, Mediterranean). One class will be dedicated to the Archean (geodynamics and georesources).

Presentation of current knowledge and concepts on ridges, oceanic subduction, and orogenic processes. Acquisition of general knowledge on Earth geodynamics, plate tectonics, and the mechanisms of deformation of the continental and oceanic crust.

Classic STU training.

Continuous assessments (2 to 3) and final exam.

Fundamental concepts of the geodynamics of divergent and convergent plate boundaries, the rheology of the continental and oceanic crust, and deformation processes at the crustal and lithospheric scales.
