Abstract

The purpose of this study is to construct the geological evolution of the Enez Delta. The Lower Meriç Delta and its offshore continuation, the Enez Delta, comprise very well developed sedimentary units with abandoned channel mouths, coastal bars and a prodelta lying on the older submarine delta far offshore with steep slopes. In the late Pleistocene, the shelf area over an Upper Miocene basement was flooded during the Riss-Würm interglacial period, exposed in the Würm glacial stage, and reflooded during the Flandrian transgression (Holocene), with each sea-level change characterised by seismic stratigraphic unit. The historical maps together with maps reconstructed on the basis of archaeological data show a rapid infilling of a large bay in the Enez area during the last 3000 years.
