The ages obtained for the succession range from Bartonian (Eocene) to Rupelian (Oligocene). The results of the study of the sedimentary facies and the evolution of the depositional rates suggest a start of the deformation of the Catalan Coastal Ranges at Bartonian (17n) and an accerelation of this deformation at upper Priabonian (13r). The Vilanova de Prades section has been measured in sediments deformed by an anticline-syncline flexure and those sediments have been correlated to other belonging to magnetostratigraphic sections in undeformed central parts of the Ebro basin. After the isopach geometry of the chronostratigraphic units obtained from the correlation between marginal (folded) and central (unfolded) basin sections we can state that main deformation (folding) took place totally after the se...

However, details of this structural inheritanceand its evolution through geological time is still under discussion. In this work wepresent two structural cross-sections based on fieldwork, well and magnetotelluric data in order to illustrate the structural styles and tectonic evolution of the Gaia-Montmell High. Here, the Montmell Fault not only constitutes the SW segment of one of the major Neogene faults in the Catalan Coastal Ranges (the Montmell-Valles Fault System), but also the NW limit of a Late Jurassic-Early Cretaceous extensional basin(the Montmell-Garraf Basin), facts that denote a major role of this fault in the tectonicevolution of the area. The present-day structure of the Gaia-Montmell High resulted, therefore, from two successive episodes of inversion during the Cenozoic. The first one reactivated the Montmell Fault as compressional during the Paleogene. As a result, and among other inversion-related structures, the Gaia-El Camp Thrust developed asa major NW-directed basement footwall shortcut. Later on, the previously formed compressional structure during the Paleogene became reactivated as extensional during the Neogene. During this phase, the reactivation of the Montmell Fault looks limited and. Hence, the extension is transmitted to the Baix Penedes Fault. On the other hand, the reactivation of the Gaia-El Camp Thrust is also manifest in the development of an array of extensional faults in the backlimb of the Carme-Cabra Anticline that corresponds to the NE-end of El Camp Fault. This episode of negative inversion developed accommodation zones between the four major faults present in the area (the Valles-Penedes, Montmell, El Camp and Baix Penedes faults) that are characterized by the presence of relay ramp-breaching faults.
