Project description: 

This PhD is part of the OROGEN project, co-funded by Total-BRGM-INSU, which attempts to better constrain the processes associated to orogens formation, from pre-orogenic inheritance to post-orogenic evolution, by the study of the Pyrenean system.

The aim of my PhD is to understand the role of inheritance (structural, compositional and thermal) of rift systems on the formation and the architecture of collisional orogens. The first part of the project is to determine and to define the Pamplona transfer zone (western Pyrenees) and to assess its role during extension and later convergence. The second part focuses on describing rift structures and rift domains in the eastern Pyrenees in order to pursue the work of J.Tugend, S.Jammes and E.Masini in the western Pyrenees. Finally, the third part consists in testing the models of reactivation developed from the beginning of the PhD to selected compressional systems in the world.
