Syn-tectonic sediments (growth strata) in compressional structures are three-dimensional (3D) features whose geometry reflects both the style of deformation and the distribution of accommodation space in the system. Previously, numerical modelling of growth strata in compressional settings has generally been done in two-dimensions in the plane of the transport direction. In contrast, in this paper we examine growth strata associated with a 3D fault-bend fold that exhibits variations in slip along-strike. A forward numerical modelling approach is used to investigate the 3D geometry of syn-tectonic sediments under a variety of conditions.
