This dataset consists of three images resulting from a sandbox analog modeling experimental program. Sandbox analog modeling of tectonic processes is an experimental technique aiming to simulate and study natural geological processes by means of scaled models. Experimental models are scaled in dimensions, time and rheology, by using different analog materials such as colored sand or silicone. Models are performed in sandboxes that contain the analog materials. These analog materials are deformed according to specific testing parameters. At the end of the experiments, models are consolidated and sliced, and these slices photographed (sections). The figures in this dataset represent the uninterpreted sections of three sandbox analog models that experimentally simulate a salt-bearing rifted margin, a salt-bearing rifted margin incorporated into fold-and-thrust belt and a salt-bearing rifted margin incorporated into fold-and-thrust belt that grown coeval with surface processes (erosion and sedimentation). The experimental program was executed at the GEOMODELS Analogue Modelling Laboratory at the University of Barcelona.
