Évolution et dynamique de la Terre

Earth Evolution and dynamics

This theme studies the continuity of processes at work from the base of the upper mantle to the atmosphere and their evolution on geological time scales. The GET relies on state-of-the-art analytical and rigorous dating facilities to determine the dynamics of the processes: geochronology, thermochronology, and stratigraphy for the surface environments. It also relies on numerical and analogical modeling tools to understand the dynamics of the processes and their coupling. This theme explores the crustal formation and growth processes, and orogenic processes. It also examines the basin’s evolution, biodiversity, and marine environment changes. The notion of couplings between lithospheric processes (e.g., deformation, displacement, magmatism, metamorphism) and their consequences at the Earth’s surface (e.g., on landscape dynamics, coastline evolution, erosion, and material transport, oceanic and continental sedimentation, climate evolution), is a key element of GET studies. The study of living organisms as drivers or markers of global changes in the evolution of the Earth’s surface is also part of this field of research.
