Description
The aim of this course is to recall and complete the knowledge of fundamental notions concerning the formation of the oceanic crust and the relations with magnetism and hydrothermalism, the birth, the functioning and the 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). Couplings between tectonics and surface processes will also be discussed.
These notions will be supported by theoretical and physical models, largely illustrated by natural case studies (Himalaya-Tibet, Taiwan, Alps, Western Pacific, Sumatra, Mediterranean). A course will be dedicated to the Archaean (geodynamics and georesources).
Objectives
Presentation of a state of knowledge and concepts on ridges, oceanic subduction and orogenic processes. Acquisition of a general knowledge of terrestrial geodynamics, plate tectonics and the mechanisms of deformation of the continental and oceanic crust.
Necessary pre-requisites
Classical STU training.
Knowledge control
Continuous assessment (2 to 3) and final exam.
Syllabus
Fundamentals of divergent and convergent plate boundary geodynamics, rheology of continental and oceanic crust, deformation processes at crustal and lithospheric scales.
