Abstract

In this paper, the AA. analyse the depositional history of the Cíes Islands barrier-lagoon system, based on lithofacies, radiocarbon ages, and pollen analysis. The results reveal a sedimentary sequence that provides evidence for striking changes in the dynamical functioning of this complex since the mid-Holocene. This resultant sedimentary sequence suggests that climatic conditions played an important role controlling the sedimentation regime during the entire history of the basin; changing water-table levels during early stages of evolution and increasing storminess during more recent times. In addition, background sea-level rise related to the Holocene transgression was a key factor in controlling the evolution of the system, yet its influence depended to an extent on the relative elevation of the bedrock topography
