Itinerary 1. Where the Pyrenees Meet the Sea: Geomorphological Evolution of the Corbières Orocline
Résumé
Itinerary 1 showcases regional tectonic and sedimentary evolution during the Oligocene and Miocene. The successive stops track landscape evolution and base-level changes during the Neogene by examining fault systems, sediment lithostratigraphy and provenance, and erosion surface vestiges crosscutting folds and structures of the North-Pyrenean and Sub-Pyrenean zones. Stops include sites where the planar land surfaces have been dated by various methods, and where their geodynamic and palaeoclimatic context can be reconstructed from a variety of environmental archives. Insights are also gained into the Pleistocene and Holocene evolution of the coastal plains, highlighting the recurrence of catastrophic flooding in the valleys.
