The Zagros foreland basin located in southern Iran is a Neogene-Recent sedimentary basin that is forming in response to ongoing collision between the Arabian and Eurasian plates. Its superb exposure, high rates of deformation and sedimentation and abundant oil and gas reserves make it a unique natural laboratory to better understand foreland basins in general. The primary goal of this project is understand how the Zagros foreland basin formed and in particular, to evaluate how the rheology of the deforming fold-thrust belt controlled the adjacent basin. This project forms the PhD topic of Mortaza pirouz who began work at the University of Geneva in June 2008. He is supervised by Guy Simpson, (University of Geneva).
