“…8f). These new results contribute to a growing body of work describing and quantifying in time and space the role of salt during different stages of the cycle (e.g., Lopez-Mir et al, 2014Saura et al, 2016;Caméra and Flinch, 2017;Labaume and Teixell, 2020;Hudec et al, 2021). The structural and stratigraphic complexity of inverted saltrich rift systems, the difficulties in estimating original salt volumes and its depletion or migration through time, render the construction and restoration of cross-sections and basin geometries particularly challenging in this orogen (e.g., see Rowan and Ratliff, 2012).…”

“…3 and 8). Triassic evaporites thin under the Montsec thrust sheet and to a lesser extent below the Serres Marginals (e.g., Vergés, 1993;Saura et al, 2016;Caméra and Flinch, 2017;Hudec et al, 2021). The Aptian-Albian syn rift successions of the Bóixols and Upper Pedraforca thrust sheets originally lay along the northern rifted margin of the Iberian plate.…”

The Pyrenees is a collisional orogen built by inversion of an immature rift system during convergence of the Iberian and European plates from Late Cretaceous to late Cenozoic. The full mountain belt consists of the pro-foreland southern Pyrenees and the retro-foreland northern Pyrenees, where the inverted lower Cretaceous rift system is mainly preserved. Due to low overall convergence and absence of oceanic subduction, this orogen preserves one of the best geological records of early orogenesis, the transition from early convergence to main collision and the transition from collision to post-convergence. During these transitional periods major changes in orogen behavior reflect evolving lithospheric processes and tectonic drivers. Contributions by the OROGEN project have shed new light on these critical periods, on the evolution of the orogen as a whole, and in particular on the early convergence stage. By integrating results of OROGEN with those of other recent collaborative projects in the Pyrenean domain (e.g., PYRAMID, PYROPE, RGF-Pyrénées), this paper offers a synthesis of current knowledge and debate on the evolution of this immature orogen as recorded in the synorogenic basins and fold and thrust belts of both the upper European and lower Iberian plates. Expanding insight on the role of salt tectonics at local to regional scales is summarised and discussed. Uncertainties involved in data compilation across a whole orogen using different datasets are discussed, for example for deriving shortening values and distribution.

“…As in other regions, these new studies have revealed details about the mechanical control that the depositional configuration of salt exerts on extensional and contractional deformation, especially in the evolution of individual thrust systems (e.g. Burrel & Teixell, 2021;Hudec et al, 2021;Jackson et al, 1994, and references therein). In some works, salt tectonics sometimes challenges crustal tectonism associated with extension and inversion/contraction stages as the main driving mechanism of sedimentary basin formation and inversion, thus substituting horizontal tectonics with vertical mass movements.…”

Salt tectonics vs. inversion tectonics: The anticlines of the western Maestrazgo revisited (eastern Iberian Chain, Spain)

Many works in the last decades underline the role of evaporites, not just as a conditioning factor but as the engine for subsidence and eventually basin inversion.The western Mediterranean alpine ranges are being investigated in this regard because of the presence of discontinuous units of Permian to Triassic evaporites, deposited in the western Tethys basins. This work presents a thorough analysis EAGE LIESA et al.

“…The other extended its influence to the westernmost area and must have entered the basin following a more meridional sediment routing through the Priabonian Salinar and/or the Rupelian lower Peraltilla Formations of the autochthonous foreland basin [157], which are characterized by absent or scarce epidote (Figure 9b). The axially-fed system enriched in epidote is sourced from the central Pyrenees, from the same source areas as the Sis and Gurp alluvial fan conglomerates, where Triassic dolerite rock fragments (bearing abundant epidote) are frequent (northern part of the Central South Pyrenean Unit), with abundant Keuper diapiric occurrences [158][159][160]. However, the Ap+ZTR dominant system must be sourced from a farther, more eastern sector of the southern Pyrenees, where Triassic dolerites of the Keuper facies are less abundant or absent (Pedraforca-Port del Comte area and present-day Segre Valley, Eastern Pyrenees).…”

Combined sandstone petrography and heavy mineral analysis allow to decipher different sediment routing systems that could not be resolved by one method alone in the South Pyrenean foreland basin. We apply this approach to deltaic and alluvial deposits of the southern part of the Jaca basin, and in the time equivalent systems of the nearby Ainsa and Ebro basins, in order to unravel the evolution of source areas and the fluvial drainage from the Eocene to the Miocene. Our study allows the identification of four petrofacies and five heavy-mineral suites, which evidence the interplay of distinct routing systems, controlled by the emergence of tectonic structures. Two distinct axially-fed systems from the east coexisted in the fluvial Campodarbe Formation of the southern Jaca basin that were progressively replaced from east to west by transverse-fed systems sourced from northern source areas. In the late stages of evolution, the Ebro autochthonous basin and the Jaca piggy-back basin received detritus from source areas directly north of the basin from the Axial Zone and from the Basque Pyrenees. Coupling sandstone petrography with heavy mineral provenance analysis allows challenging the existing model of the South Pyrenean sediment dispersal, highlighting the relevance of this approach in source-to-sink studies.
