Research topics

Research at Géosciences Rennes is basically focused on the analysis of processes that drive Earth dynamics at various space and time scales, with approaches combining Observation, Measurement, Experiment, and modelling.
Research topics concern the internal Earth, surface processes, and coupling between envelopes :
Fluid transfers within heterogeneous medias, water cycles and element reactivity, interactions between water-minerals-bacteria, geomagnetism, geophysical imaging, continental erosion, paleo-environments, continental margins, sedimentary basins, dynamics of tectonic systems, dating of geological processes.

The research benefits of several internal and external technical supports, including in particular experimental modelling, and active participation to national observation structures (Observatoire de Recherche en Environnement H+, Observatoire de Recherche en environnement Agrhys, Réseau National GPS RENAG, Observatoires volcanologiques et sismologiques).
Géosciences Rennes is part of the “Observatoire des Sciences de l’Univers de Rennes (Terre, écosystèmes et Sociétés)†, which is a component of the University and comprises 7 Departments involved in environmental research end teaching.


The Department is organized in 9 research groups :
- Tectonic systems Systèmes tectoniques
- Tracing and dating of processes Terre, temps, traçage
- Erosion and river dynamics Erosion et dynamique fluviatile
- Water and interfaces geochemistry Géochimie des eaux et des interfaces
- Water and matter transfers within complex heterogeneous media Transferts d’eau et de matière dans les milieux hétérogènes complexes
- Basin dynamics Dynamique des bassins
- Biodiversity Biodiversité : interactions, préservation, évolution
- Geomagnetism Géo et Archéomagnétisme
- Geophysical imagery Imagerie géophysique des systèmes complexes
