Abstract
Deformation fronts of fold-thrust belts vary widely in type, geometry and spatial organization. This contribution seeks to understand the effect of lateral variation of intermediate decollement on the deformation front geometry of the ZFTB using analogue models. In order to understand the effect of lateral variation of intermediate decollement on the deformation front geometry of the ZFTB, we will successively focus on two particular regions where recent studies has been done: the Izeh zone and Lurestan which are both situated in the Zagros simply folded belt adjacent togetherIn this study, we use systematic scaled analogue models to investigate the effect of spatial distribution of the intermediate decollement on the deformation style in the Zagros fold and thrust belt.
