Abstract
Two depositional sequences related to sea level changes are described and dated for two
neighborough beaches in Cantabria ( Northern Spain), The oldest unit is a beach sequence consisting of
basal gravels, clays and eolian sands. The aminoacid racemization analisis of two types of moluscs show
a discrepant age (71 570 + 13 400 and 21 140 ± 9 400 Y BP). Outcrop data and general sea stages
arrangement, however, allows us to support a preglaciar age for this beach level. The second unit
incises at least three meters in the older one and consists of peat deposits with tree stems and organic
matter rich clays, representing an estuarine plaine. Radiocarbon dating gives an age of at least 6 210 ±
85 y BP for it and can be interpreted as the postglacial sea rise level.
