Full textSurface processes changes resulting from tectonics and climate interactions are potentially preserved by the sedimentary record. Here we focus on the North Iberian plate, which records each phases of the alpin cycle. In order to study the detrital content evolution from rifting to mountain formation we use a combination of low temperature thermochronometers. First, results allow us to constrain the tectono-thermal and detrital histories of the Cameros inverted mesozoic rift basin over 100 Ma. Then, new thermochronological, petrological and geochronological data lead us to extend this observation at the Ebro basin regional scale and to explore the detrital thermochronology potential bias on the source signal. Finally, these results are integrated into a reconstruction proposal of the Iberian paleogeography, from the Oxfordian to the late Miocene

Full textNew thermochronological data (AFT, ZHe, and ZFT) on the Belledonne and Grandes Rousses ECMs basement show a similar and relatively rapid exhumation dynamic around 18 Ma for all the External Cristalline Massifs. However, the exhumation of southern massifs (e.g., Oisans) could start earlier, from 25 Ma suggesting a diachronous exhumation along the Alpine Arc. This also suggests a progressive localization of deformations along the crustal ramps between ~25 and 18 Ma. Finally, the rapid exhumation starting at around 18 Ma seems to correspond to the limit of mega-sequences in the molassic basin. Field analysis, borehole data and seismic lines show that the basin was deformed as early as the Oligocene (25 Ma). This also allows the calculation of the sediment volumes preserved within the West Alpine Molassic Basin. Finally, a preliminary study of the source to sink in the West Alpine basins is approached from petro-detritic analyses, detrital thermochronology and calculation from the seismic lines. These results highlighted the progressive denudation of the Variscan crust of the upper plate whose detrital signal has been present since the Eo-Oligocene in the peri-alpine basins. The late Miocene appearance in the West Alpine Molassic basin of a tertiary thermochronological signal suggests a change in surface dynamics and/or a different sedimentary routing over time, but also significant differences compared to the basins located north of the Alps

Full textThe formation of orogenic arcs results from several tectonic processes that may have affected the pre-orogenic, pre-collisional tectonic setting, or the collisional tectonic. The formation of the Western Alpine arc is classically attributed to collisional indentation of the European margin and the orogenic prism by the Adriatic indenter. However, the direction of indentation, its rotational component, or the accommodation mechanisms of this indentation are not agreed upon and the numerous kinematic models of the arcuate geometry of the chain are not compatible with one another. The evaluation of the different models of the formation of the Western Alpine arc allows to put forward the probability of the existence of a proto-arc inherited from the subduction phase, and amplified by the Adriatic indentation towards the NW. These two processes explain the formation of the Western Alpine arc, except for its E-W southern termination. Indeed, the orientation of the Castellane Arc seems to be mainly inherited from the Pyrenean-Provençal structures, preceding Alpine collision, and reactivated by post-Tortonian (~12 Ma) N-S convergence, not directly related to Alpine collision. Concerning the WNW-ESE direction of the southern termination of the arc, which forms the Ligurian Alps, it seems to have rotated counterclockwise by 50° with the northern Apennines, linked to the rollback of the Adriatic slab, contemporary with the opening of the Liguro-Provençal basin (23-15 Ma). A compilation of paleomagnetic data in the Alps was constructed and completed with 11 new data sites. The study of vertical-axis rotations, estimated by paleomagnetic analysis refutes the existence of significant rotation of the Adriatic plate during Alpine collision. Oroclinal tests, carried out at several scales, show that the Western Alpine arc develops under the effect of indentation towards the NW from an orogenic prism that is already weakly arcuate before the onset of collision. Furthermore, the European continental margin does not seem to undergo significant rotation, implying propagation of an arc that is mainly inherited from the Mesozoic passive margin. The present geometry of the Western Alpine arc would be mainly controlled by the pre-collisional structure of the European margin that the orogenic prism adopts under the effect of NW Adriatic indentation. Its southern termination would have a different geodynamic history. It would be the result of Pyrenean-Provençal inheritance, reactivated during the Miocene in the External Zone, and of an anti-clockwise rotation of the Internal Zone, linked to the Apennine orogeny. Adriatic indentation, sometimes assumed to follow a westward trajectory, would be accommodated to the south of the arc by a sinistral shear zone of about 50km according to literature. This interpretation is tested by a structural field study, associated with a geostatistical analysis of map trajectories of the schistosity and stratigraphy planes. The results confirm the existence of sinistral shear zones associated with syn-collisional transpressive tectonics. However, these faults seem to represent minor structures with respect to the accommodation of 50 km of displacement. This structural analysis has also highlighted polyphase deformation in the Dauphinois, associated with localised mylonitisation is characterised by a N120° stretching. The assessment of the maximum temperatures by the RSCM method indicates temperatures above 350°C at the northern edge of the Argentera, reaching locally 400°C, corresponding to a regional metamorphism that is more important than the one attributed to this sector of the Alps. This metamorphism is mainly associated with tectonic burial due to thrusting of the internal nappes on the Dauphinois at the beginning of collision. In the Argentera Massif region, the Tmax in the Dauphinois correspond to a burial depth of 11.3 ± 1 km at the level of the Pennine Front, decreasing to 4 km below the Castellane arc

Full textThe aim of this study is to characterize the Plio-Quaternary tectonic deformations related to the Belledonne fault system (western Alps). The low deformation rates and high erosion rates in the study area imply that a multi-disciplinary approach.From the Bauges to the Vercors massif this fault system is composed of strike-slip faults that are the NE trending right-lateral strike-slip Arcalod fault, the NE trending right-lateral strike-slip Belledonne border fault, the NW trending left-lateral strike-slip Brion fault and the NE trending right-lateral strike-slip Jasneuf fault.The determination of the late Cenozoic stress states revealed that the modern stress field responsible for the Belledonne fault system strike-slip kinematics dates from late upper Pliocene/early Pleistocene and came after the stress field caused by alpine collision.Unclear and undated (but probably pre Rissian) offset morphologic markers are described along the Arcalod and Brion faults. Belledonne border fault trace is not determined suggesting that deformation is accommodated in a wide shearing band.The Jasneuf fault offset morphologies whom ages are supposed Messinian and pre Rissian. Fault slip rate integrated since Messinian would be of 0.13±0.03 mm/yr. Considering that this fault appears limited to the sedimentary cover and excluding an aseismic behavior, she can generate 5.7 Mw earthquake each ~500 years.Modern deformation in the foreland is studied in the Toulaud valley (SW of Valence city) where a late Hercinian fault cross-cut the Messinian canyon of the Rhône river. First results show that the fault offset vertically the canyon, attesting aof Plio-Quaternary tectonics along it
