Geosciences Environnement Toulouse - CNRS -Université Paul Sabatier

We are looking for 1 PhD candidate within the new Marie Skłodowska-Curie Action – Doctoral Network INITIATE dedicate to Climate – Tectonics interactions using Big Data and Numerical models. INITIATE brings together 5 academic beneficiaries: University of Bergen, CNRS, University of Barcelona, University of Potsdam, and Helmholtz-Centre Potsdam – German Research Centre GFZ. It also includes 13 partners from the academic world (Université Paul Sabatier Toulouse III, IFP Energies nouvelles, University of Athens), the public sector (Institut of Cartography of Catalogna, UNESCO Geoparc Orígens, The Norwegian Water Resources and Energy Directorate), the energy industry (TotalEnergies, Repsol, Aker BP ASA, Equinor, Vulcan Energy Resources) and satellite data (GAF AG, DELPHI IMM GmbH).

We are still looking for 1 doctoral candidate for the DC12 position – Stratigraphic signature of the 3D evolution of rift systems (Suez Rift) following the Neogene climate change Géosciences Environnement Toulouse – Supervision: Delphine Rouby Sébastien Rohais

Stratigraphic architecture of sedimentary basin records Earth surface evolution, especially in high accommodation high sediment supply basin, such as rift systems. How climate modulates erosional processes (speed, timing, rate) and longer-term processes such as tectonic is key to understand and spatialize future landscape evolution. Significant advances, made in the 1990’s in the understanding of the stratigraphic signature of crustal deformation and climate do not include the “state-of-the-art” understanding of lithosphere deformation gained in the last 20 years nor the implications of the coupling with surface processes (erosion/sedimentation). We aim to modernize our understanding of the stratigraphic architecture of continental rifts by including the contribution of lithosphere deformation, its coupling with surface processes, as well as the evolution of climate evolution controlling their efficiency.
To do this, the doctoral candidate will use the HR basin dataset of the Suez Rift of the IFPEN to map in 4D this continental surface undergoing rifting as well as the associated depositional environments and reliefs (i.e., paleo-geological mapping method, Year 1). the doctoral candidate will then perform a numerical parametric analysis of rift systems to establish the respective contribution of tectonics and climate on the stratigraphic architecture its associated basins (Year 2). the doctoral candidate will evaluate the geodynamic implications of the observed evolution of the Suez Rift and other well documented rift systems (Year 3). Finally, the impact of the climate will be isolated from the tectonics one to define its impact on the timing and amplitude of erosional processes (Year 3).
