An unusual Holocene fan-shaped subaqueous prograding body at the back of the Cíes Islands ridge (Ría de Vigo, NW Spain): Geomorphology, facies and stratigraphic architecture

The combination of geophysical and radiocarbon data leads us to establish the beginning of the progradation of the sedimentary body subsequent to the Younger Dryas cold event, associated with the Holocene sea level rise. The seismic analysis of the high-resolution seismic records allows us to recognize five main clinoform sets inside the subaqueous prograding sedimentary body, which can be attributed to sea level changes during the Holocene.
