摘要：The coastal area of western Peloponnese is characterized by Pleistocene and Holocenemarine deposits. The study area shows the effects of different phases of coastal morphologyevolution and is located along a wave-dominated and microtidal coast in the northwesternPeloponnese, 40 km southwest of Patras city.Three significant morphogenetic phases occurred during the Holocene.The first was radiometrically aged from 7000 to 3810 years BP, marking the end of therapid postglacial transgression.The second, between 3810 and 1400 years BP, was characterized by high rates ofsedimentation, possibly because of the proximity of the mouth of the Peneus River, and resulted inthe accumulation of predominantly fluvial sediments.During the third and younger phase, from 1400 years BP to the present, landwardmigration of the coast and deposition of aeolian sands occurred. Archaeological andmorphological evidences suggest that this last phase should be related to a low sea-level standfollowed by a slow sea-level rise, up to the present-day position and by humid-temperate climate.The collected data concerning the Holocene coastal dune belts, suggest that main phasesof dune development could be related to the effects of sea-level changes, climatic conditions, andin a subordinate way, to human activity.
