Orogenesis represents the final phase of the Wilson Cycle. As such, structural, compositional and thermal properties of the lithosphere and mantle, inherited from preceding phases can influence the evolution of the orogen. The properties and characteristics of the orogen itself can, in turn, influence post-orogenic geodynamic processes (e.g. collapse, lithospheric re-equilibration, a new extensional cycle, etc...). The Pyrenean mountain belt documents more than 300 Myrs of geodynamic history from the Variscan orogeny, followed by Mesozoic rifting, to the Alpine orogenic event. Moreover, the foreland basins around the Pyrenees provide unique records of syn-orogenic processes. Investigating these characteristics has been the motivation of several research projects over the last two decades. These projects are providing an extensive database that make the Pyrenees an ideal natural laboratory to understand the role of inheritance (thermal, structural, compositional) in rifting and orogenic processes. This session aims to bring together researchers involved in integrated studies of structural and metamorphic behaviour on all scales, basin and sedimentological analyses, numerical and analogue modelling and dating of deep to surface processes (thermochronology, geochronology, etc) as applied to the Pyrenean domain. We are particularly interested in studies that evaluate the impact of inheritance on orogenic processes at different spatio-temporal scales in the Pyrenean/Iberian realm.
