Fig. 2From: Growth-strata geometry in fault-propagation folds: a case study from the Gafsa basin, southern Tunisian AtlasGrowth-strata geometry in Sant Lorenç region, northern Spain. In this example, the numbers 1 and 2 correspond to two sequences of growth strata separated by a hinge migration tectonic event. a Cross section adapted after Ford et al. (1997). b Model simulation adapted from Rafini and Mercier (2002)Back to article page
