Abstract
The Corrubedo beach-lagoon complex is situated in an embayment on the northwestern coast of Spain. The 4.1 m tidal range and southwesterly winds are the main agents of sediment transportation. The sediments are hybrid arenites (siliciclastic + bioclastic), with carbonate percentages ranging from 27.36 to 54.10%; silt, clay and organic matter occur in minor amounts. Repeated mapping and sampling of the beach, tidal channels, salt marshes and active and vegetated dunes recorded the vertical facies associations and their temporal evolution. Two peat layers at 0.6 and 1.7 m below the present-day marsh have yielded ages of 2280 ± 60 yrs B.P. and 1045 ± 125 yrs B.P. respectively. The possible causes of the relative sea-level rise are discussed.
