“…13d). Similar fluid migration from a deep siliciclastic aquifer toward shallower carbonate successions and related diagenesis has been recently studied in detail on both sides of a high-angle basement-involving normal fault, namely the Uzer Fault in the Ardèche margin of the French Alpine foreland (see Bonijoly et al, 1996;Léost et al, 1995Léost et al, , 1998Léost, 1998;Ramboz et al, 1999;and references therein).…”

Résumé -Impact de la tectonique et de la migration naturelle des fluides sur l'évolution des réservoirs dans les chaînes plissées et leurs avant-pays -Nous avons utilisé ici les résultats d'études de cas réalisées dans plusieurs chaînes plissées et leurs avant-pays au moyen d'une méthodologie intégrant la géologie structurale, la pétrographie, la fabrique magnétique et les modélisations de bassin. Cette méthode permet d'identifier les paramètres critiques et les processus contrôlant l'évolution des réservoirs depuis la fin du développement de la marge passive jusqu'aux épisodes postorogéniques de collapse de l'édifice tectonique. Les interactions fluides-roche sont exacerbées pendant les périodes de crise tectonique. La compaction tectonique est déjà active dans l'avant-pays, tandis que le développement et la réouverture de réseaux de fractures permettent de remobiliser les fluides dans les unités allochtones, d'expulser les fluides préalablement rééquilibrés des roches-réservoirs, mais aussi d'injecter de nouveaux fluides exotiques, en déséquilibre chimique, dans les drains carbonatés ou gréseux. Dans les bassins subandins, la cimentation siliceuse est ainsi dominée par les effets de la compression tectonique (raccourcissement parallèle aux couches ou LPS) dans les unités sous-charriées à proximité du front de la déformation. Le LPS est aussi suspecté de contrôler la recristallisation des mésodolomites dans l'avant-pays des montagnes Rocheuses au Canada. En revanche, la dolomitisation secondaire par processus hydrothermaux des niveaux carbonatés permet souvent une migration latérale des fluides diagénétiques le long d'horizons stratigraphiques peu pentus dans l'avant-pays, mais aussi l'échappement vertical de fluides minéralisateurs dans les réseaux de fractures ouvertes de l'allochtone. Inversement, le développement de porosité vacuolaire dans les séries carbonatées allochtones de la Cordillère nord-américaine peut s'expliquer par un refroidissement progressif du réservoir dans un système relativement clos, en liaison avec la surrection tectonique et l'érosion progressive des séries superficielles. Les modélisations de bassin permettent d'obtenir des estimations réalistes des paléo-températures et des paléo-enfouissements atteints par un réservoir donné, valeurs qui peuvent être ensuite comparées à des paléo-thermomètres tels que les inclusions fluides ou les isotopes stables, permettant ainsi de dater de Gas-Water-Rock Interactions ... / Interactions gaz-eau-roche ...

The Rhône River Valley in France, a densely populated area with many industrial facilities including several nuclear power plants, was shaken on November 11th 2019, by the Mw 4.9 Le Teil earthquake. Here, we report field, seismological and interferometric syntheticaperture radar observations indicating that the earthquake occurred at a very shallow focal depth on a southeast-dipping reverse-fault. We show evidence of surface rupture and up to 15 cm uplift of the hanging wall along a northeast-southwest trending discontinuity with a length of about 5 km. Together, these lines of evidence suggest that the Oligocene La Rouvière fault was reactivated. Based on the absence of geomorphic evidence of cumulative compressional deformation along the fault, we suggest that it had not ruptured for several thousand or even tens of thousands of years. Our observations raise the question of whether displacement from surface rupture represents a hazard in regions with strong tectonic inheritance and very low strain rates.

“…A first extensional event was at the origin of the formation of normal faults throughout the region during early Jurassic times. The Liassic age of this episode is well constrained due to the presence of kilometre-scale normal faults associated with progressive unconformity outcropping on the southern border of the Grands Causses domain [63][64][65]. The compressive tectonic structures of the Grands Causses domain (either neoformed or normal fault reactivation) have been related by previous authors to the nearby orogen, i.e., the Pyrenean orogen building during the Eocene period [13,45,66].…”

Tectonic Record of Deformation in Intraplate Domains: Case Study of Far-Field Deformation in the Grands Causses Area, France

et al. 2020

Although tectonic plates are usually considered as rigid blocks, intraplate deformation such as lithospheric buckling or diffuse brittle deformation has been recognized for a long time. However, the origin of these deformations remains puzzling. Indeed, whereas the chronology of deformation at plate boundaries can be constrained by numerous methods (syntectonic sedimentary record, thermochronology, etc.), dating of brittle structures (faults, veins, and joints) in the far-field domains remains challenging, preventing a global interpretation of the system as a whole. In this contribution, we have combined a tectonic study with a synkinematical geochronological study of fault-related calcites of the Grands Causses intraplate domain, north of the Pyrenean orogeny. We show that these faults record a much longer history of deformation than previously thought. The Mesozoic extension, usually attributed to an early Jurassic Tethysian rifting event, probably lasted until the Barremian-Aptian epoch, in response to the Pyrenean basin’s opening. The so-called “Pyrenean deformation” of the Grands Causses domain, usually associated with the paroxysm of deformation in the belt during the late Eocene, began much earlier, around 100 Ma, and lasted for more than 60-70 Ma. This study demonstrates the high sensitivity of an intraplate domain (Grands Causses area) to record extensional or compressional deformations occurring at the edge of neighbouring plates.
