“…In the Basque-Cantabrian Basin, the Ventaniella Fault is part of a NW-SE fault system that acted as left-lateral shear zone during the Late Jurassic-Early Cretaceous and has been subsequently inverted with a right-lateral kinematic during the Cenozoic (De Vicente et al, 2011;Tavani et al, 2011;Cámara and Flinch, 2017). These faults have a Triassic origin (Tavani and Granado, 2015).…”

A reconstruction of Iberia accounting for Western Tethys–North Atlantic kinematics since the late-Permian–Triassic

et al. 2020

Abstract. The western European kinematic evolution results from the opening of the western Neotethys and the Atlantic oceans since the late Paleozoic and the Mesozoic. Geological evidence shows that the Iberian domain recorded the propagation of these two oceanic systems well and is therefore a key to significantly advancing our understanding of the regional plate reconstructions. The late-Permian–Triassic Iberian rift basins have accommodated extension, but this tectonic stage is often neglected in most plate kinematic models, leading to the overestimation of the movements between Iberia and Europe during the subsequent Mesozoic (Early Cretaceous) rift phase. By compiling existing seismic profiles and geological constraints along the North Atlantic margins, including well data over Iberia, as well as recently published kinematic and paleogeographic reconstructions, we propose a coherent kinematic model of Iberia that accounts for both the Neotethyan and Atlantic evolutions. Our model shows that the Europe–Iberia plate boundary was a domain of distributed and oblique extension made of two rift systems in the Pyrenees and in the Iberian intra-continental basins. It differs from standard models that consider left-lateral strike-slip movement localized only in the northern Pyrenees in introducing a significant strike-slip movement south of the Ebro block. At a larger scale it emphasizes the role played by the late-Permian–Triassic rift and magmatism, as well as strike-slip faulting in the evolution of the western Neotethys Ocean and their control on the development of the Atlantic rift.

“…As previously suggested by Philip et al (1987) and Bestani et al (2016), the South Provence margin shows major similitudes with the Pyrenean Rift system, which is also characterized by diachronic pre-contractional halokinetic structures related to the upper Triassic Keuper evaporites (including salt-core anticlines, minibassins and raft tectonics) during Mesozoic times (Canérot et al, 2005;Biteau et al, 2006;Lagabrielle et al, 2010;López-Mir et al, 2014;Saura et al, 2016). Halokinetic deformations would start somewhat later in the Pyrenean domain (late Jurassic) and maybe also synchronously with small extensional basement deformation as described in the Eastern Bay of Biscay and the Basque-Cantabrian basin (Ferrer et al, 2012;Cámara, 2017).…”

The Provence Chain incorporated preexisting halokinetic and basement features which have played a key role in the structural evolution of the thrust systems. Field structural data, previously published geological maps and exploration well data have been used to interpret a new ~80 km-long balanced and restored cross section across the eastern Provence fold-thrust Diapiric structures were mainly eroded during and after the Pyrenean-Provence compression then reactivated during Oligocene extension and Miocene to present-day Alpine compression. Cross section balancing shows a total horizontal shortening of 28.5 km related to the Pyrenean-Provence and Alpine compressions. The eastern Provence fold-thrust belt integrates preexisting halokinetic folding which can be misinterpreted as resulting to compression. This suggests that a significant amount of folding in fold-thrust belts can results from an early halokinetic fold system developed during the pre-contractional passive margin evolution.

“…Geological and geophysical investigations have proven that the Pyrenees, a doubly vergent orogen, formed as a result of the inversion of mid-Cretaceous hyperextended rift from Late Cretaceous to Early Miocene (Clerc & Lagabrielle, 2014;Jammes et al, 2009;Lagabrielle et al, 2010;Mouthereau et al, 2014;Wang et al, 2016). The presence of the prerift upper Triassic salt (Keuper facies and sometimes Muschelkalk), in which the fold-and-thrust belt is detached, is well documented in the southcentral Pyrenees and the Basque-Cantabrian basin (Càmara, 2017;Càmara & Flinch, 2017;Canérot et al, 2005;Ducoux et al, 2019;Saura et al, 2016). Due to the plate kinematics between Iberia and Europe, and the mobility of the Triassic salt during the Early Cretaceous extension, the Keuper décollement layer is unevenly distributed throughout the Pyrenean rift system (Càmara, 2017;Lagabrielle et al, 2010).…”

The Basque-Cantabrian region of the Pyrenees forms a 100-km-wide mountain belt with a smooth topography, characterized by large open synclines and well-preserved passive salt diapirs and ridges, and associated minibasins (Càmara, 2017).…”

Topographic and Tectonic Evolution of Mountain Belts Controlled by Salt Thickness and Rift Architecture

The role of the heterogeneous rheological architecture of rifted margins in the building of mountain belts has challenged our view of how a collisional orogen formed. We show, using two-dimensional numerical experiments of collision built by the inversion of rifted margins, that a weak pre-extensional evaporitic layer delays the growth of topography and the onset of syn-orogenic sedimentary record in foreland basins. In tectonic models lacking a weak décollement layer, the orogen grows by progressive accretion of basement thrusts. With a 2-km-thick salt layer, the orogen develops an antiformal stack in the deep crust that is kinematically connected to a shallow thin-skin thrust belt in the foreland as observed in many orogens. A 5-km-thick weak layer leads to the quasi-absence of topography and widespread salt tectonics and obliterates thrusts propagation while promoting crust and mantle underthrusting. During convergence, the preservation of a marine seaway emphasizes that collision may involve a significant period of submarine continental accretion, which duration is controlled by the thickness of the weak décollement layer. From these experiments we infer that the thicker the salt layer, the longer the delay between the onset of far-field shortening and the formation of the orogen. Our study explains first-order features recognized in many orogens controlled by variable salt thickness and extension.
