dc.description.abstractThe study of the composition and provenance of the sediments from two cores from the Galician continental shelf (NW of the Iberian Peninsula) based on their textural, geochemical and magnetic properties has allowed us to reconstruct the paleoclimatic evolution of this region. Based on the temporal framework of the identified facies, it was observed that during the Holocene Optimum the continental shelf was under a high-energy regime. The most notable record of this period was a bioclastic lag founded in both cores, which could also be correlated to nearby cores. After the Holocene Optimum, the ongoing marine transgression favoured deposition of sandy sediments. The following stabilization of the sea-level favoured an increase of continental muddy sediments from the Miño and Duero rivers since the Roman Warm Period. On the contrary, this process was negligible in the outer shelf, generating conditions which allowed the neoformation of glauconitic mineralsen_US
