Quaternary tectonics: Influence on the structure of two karstic aquifers of Languedoc (France)
Abstract:
Our research focuses on the effect of Quaternary tectonics on the organization of the conduit network of karst ground water flow. In the Languedoc region, the major karstic systems are developed in Malm and Lower Cretaceous platform limestones. Most of these systems are polygenetic, their genesis and evolution having been controlled by fracturing that occurred during major tectonic phases (ante-Senonian, Eocene, Oligocene, Aquitanian, Pliocene). These complex karst systems were reactivated following Messinian eustatic events, under tectonic conditions which are not well-known, particularly those that occurred during the Quaternary. Small scale deformations and a lack of seismic activity make characterization of current tectonics in Mediterranean Languedoc difficult. The presence of vertical offsets, however, demonstrates that there are active faults in the interior of or in proximity to karst systems. In two karst aquifers within the Garden basin, we have observed a correlation between the orientations of active faults and the principal karst conduits. In the Mialet basin, we demonstrate that erosion resulting from post-Miocene uplift (and so changes of boundary conditions) divides the aquifer into smaller, independent units. In the St Chaptes basin, we reconstruct the history of the karst, proposing that tectonic and eustatic events were predominant in the karstification process and that the climatic conditions were only of secondary importance. We also show how the reactivation of faults can lead to the unblocking of abandoned karst conduits, allowing their reintroduction into the active flow system, a phenomenon that can be explained by the combined influence of the present stress field and hydraulic gradients. This work, which represents a preliminary study, leads to hypotheses that we will subsequently validate through different successive modelings
