Early Foreland Basin Depositional Evolution in NW Zagros from Latest Cretaceous to the Early Eocene

We present an analysis of the evolution of the eastern Lurestan arc after own detailed paleobathymetric and thickness maps, based on paleofacies analysis and dating of our own field stratigraphic logs and existing borehole data. Integration of these maps in a geomodel was used to generate step-by-step subsidence maps, which illustrate a south-westward migration of the basin depocenter. However, WNW-ESE trending, relatively uplifted areas can also be recognised in the internals parts of the basin, which fit the location of the main anticlines of the area. These uplifted areas migrate to the SW and we interpret them as recording an early folding stage, spanning at least from the Maastrichtian to the early Eocene.
