Summary

Geomorphology is strongly controlled by surface deformation in areas of active tectonism and distinct ‘tectonic geomorphologies’ develop. There is a close relationship between geomorphology and processes of erosion and sedimentation. Sediment distribution patterns along the southern margin of the Gulf of Corinth are controlled by the inherited pre-rift geomorphology, the evolving tectonic geomorphology, and both Mesozoic basement and basin-fill lithologies (exposed Neogene sediments). Drainage basin characteristics have a particularly important control on sediment yield and the location and nature of coarse-grained deltas. Tectonic extension in the Gulf of Corinth Basin has been concentrated along WNW–ESE trending normal faults which define prominent topographical boundaries between the Hellenide Massif of the North Peloponnese, uplifted Neogene sediments and the seismically active Gulf of Corinth. A series of offlapping, Plio-Pleistocene ‘Gilbert-type’ deltas step down to the southern shore of the Gulf. Topsets are located at altitudes up to 1700m and foresets are up to 700 m thick. Successive delta abandonment is attributed to uplift of the North Peloponnese and northward migration of faulting activity. Modern deltas are restricted to the west part of the area, whereas older deltas occur throughout the exposed Neogene basin fill. Differential movement between fault blocks coupled with regional uplift caused reversal of drainage across fault blocks, channel incision, development of new drainage basins on the emergent Neogene sediments and sediment starvation in the east of the basin.
