Lay summary
This project is a continuation of the NSF/ETH/Geological Survey of Iran (GSI) on the structural and rheological evolution of an accretionary wedge: The Makran, in Iran. This new project aims to solve critical questions that emerged from our field results concerning both the anatomy of the wedge and wedge mechanics. These questions include the early, Cretaceous to Palaeogene history of the wedge and its geodynamic context at that time as well as the influence of growth structures on wedge dynamics. To find answers, we will (1) complement our work on specific areas of the Iranian Makran, (2) extend our field area into the southern part of the Sistan suture zone and (3) direct our modelling efforts towards the coupling between thrusting and erosion-sedimentation to document and understand syn-sedimentary structures and, conversely, syn-tectonic sedimentation in a more dynamic way than the existing models allow.The project involves two PhD students, integrating remote sensing, field and modelling studies. It involves collaboration with other scientists of the Department of Earth Sciences at the ETH and will strengthen the already established collaboration with the Geological Survey of Iran and the University of Paris VI.

Abstract

This project is a continuation and extension of the NSF/ETH/Geological Survey of Iran (GSI) project started in 2004 and running out in the fall of 2009 (SNF 200020-116579 1: Structural and rheological evolution of an accretionary wedge: The Makran). Our project was the first geological study in the Iranian Makran since the 1970’s. The now proposed project extension aims to solve critical questions that emerged from our field results in the Iranian Makran concerning both the anatomy of the wedge and wedge mechanics. These questions include the early, Cretaceous to Palaeogene history of the wedge and its geodynamic context at that time as well as the influence of growing structures on wedge dynamics. To find answers, we need (1) to complement our work on specific areas of the Iranian Makran, (2) extend our field area into the southern part of Sistan suture and (3) direct our modelling efforts towards the coupling between thrusting and erosion-sedimentation to document and understand growth structures in a more dynamic way than the existing models allow.We request one Post-Doc and two PhD students to perform this study, integrating geodetic GPS with remote sensing, field and modelling studies. It involves collaboration with other scientists of the Department of Earth Sciences at the ETH and will strengthen the already established collaboration with the Geological Survey of Iran and the University of Paris VI, which is involved in studies in other parts of Iran.
