Rare earth elements as natural tracers in the Thau basin karstic system
Rare Earth Elements (REE) have been more frequently used as tracers in hydrogeology, in part due to the analytical progress made to their determination at very low concentrations. REE cannot be considered as perfect conservative tracers, but REE patterns of ground waters are mostly inherited from aquifer rocks through which they flow. As a consequence, REEs can be useful to study flow pathways and mixing processes at different scales. Because of the few REE studies realized in karstic environments, we applied the method to the karstic system of the Thau basin (southern France), which is characterized by a high complexity of water mixing processes. We were able to discriminate between the different aquifers concerned based on REE characteristics,and to investigate their possible connections.
