Abstract: Quaternary sea level fluctuations have been responsible for significant remodelling of coastal landscapes, generating distinctive sea level indicators at different positions and altitudes that are still visible today. Raised coastal deposits are among the characteristic features of significant value in reconstructing the tectonic and sea-level history of the areas in which they are preserved. To date, few remnants of Quaternary coastal deposits have been described and directly dated along the coast of the Cantabrian margin (on the north of the Iberian Peninsula). In this work, two new deposits located in the towns of Castro-Urdiales and Mendexa were analysed and dated using U/Th geochronology and Optically Stimulated Luminescence. Considering the ages and altitudes of these deposits, it seems most likely that they correlate to the Marine Isotope Stage (MIS) 5e. Furthermore, the data acquired suggest that most of the Cantabrian margin underwent a similar tectonic evolution, with no significant tectonic uplift, since at least MIS 5e.
