Earth surface processes, tectonics and geodynamics

Investigating landscape evolution as a response to tectonic and climatic forcing
  • Earthquakes and active faults
  • Erosion processes
  • Geochronology (cosmogenic nuclides and OSL)

Rivers, deltas and coastal areas

Fluvial and coastal morphodynamics and paleogeography and geoarchaeology of coastal, wetland, and deltaic environments

 

  • Observation, quantification and prediction of present-day fluvial and coastal morphodynamics
  • Coastal sediment transport resulting from meteorological and marine forcing and human activities
  • Evolution of coastal, fluvial and wetland environments in response past natural and human pressures
  • Coastal geomorphology, paleogeography and geoarchaeology of coastal, wetland and deltaic environments of Provence

Geochronometry and palaeoenvironments

Using different dating methods and paleoenvironmental reconstitution of paleo-, neo- and archaeological sites, we compare the evolution and resilience of human societies in their environmental context to the actual issues of global climate changes.

Earth's magnetic field

Spatial and secular variations of the Earth’s magnetic field
  • Rapid secular variations: paleomagnetism / isotopic geochemistry (cosmogenic nuclides) coupling
  • Recent secular variations: archaeomagnetism (burnt clays and recent lava flows)
  • Crustal magnetic field anomalies: pressure experiments and numerical modeling

Planetology

Study of Solar system solid bodies: small bodies (asteroids), planets (Mars, Earth), and their satellites (Moon)

    • Small bodies formation in the protoplanetary disk
    • Evolution of asteroid and planets (aqueous alteration, metamorphism, internal structure)
    • Impact on planetary surfaces: craters and their ejectas
