From simpler, layer-cake to 3D tapered décollement-cover sequences, our models constrain wedge evolution: a more advanced front, where the cover is thicker, promotes differential frontal translation and triggers vertical axis rotation of several hinterland anticlines which appear towards the thinner cover area. In all cases, the décollement level is strongly sheared and tends to migrate laterally toward the thinner cover areas. Models are compared with previous analog models under normal gravity and the natural example of the South Pyrenean Central salient. All in all, we conclude that a 3D tapered décollement-cover basin architecture, as a sole factor, can determine the formation of a thrust salient formed by increasing structural curvature (progressive arc). info:eu-repo/grantAgreement/ES/MINECO/CGL2010-21968-C02-02 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.1 2022 GEOSCIENCES, MULTIDISCIPLINARY 80 / 202 = 0.396 2022 Q2 T2 1.225 2022 Geology 2022 Q1 6.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Harris, Lyal B.
