Fig. 10From: Growth-strata geometry in fault-propagation folds: a case study from the Gafsa basin, southern Tunisian AtlasExpected geometry in growth strata obtained with different hinge kinematics a with hinge migration, b with limb rotation around fixed hinges (adapted from Rafini and Mercier 2002). Lines 1–5 show schematically the evolution of the fold limb in the pre-growth strataBack to article page
