New seismic reflection data in the Eastern Mediterranean, South of Cyprus,allow to better define the geological structure of the Eratosthenes Sea-mount area.This Seamount is in fact a carbonate bank made of several sequences Mid-Jurassic to Miocene in age.These carbonate platforms capped a Basement Horst, part of an Eratosthenes wider Continental Block (ECB) created during rifting from the Triassic to Liasic-Bajocian of the Africa Plate. The eastern margin of the ECB is a tilted block bonded by a "master" fault extending from the Cyprus Arc to the Nile Cone.The thick sediments of the Levantine Basin onlap on tis fault scarp or change abruptly of facies on the top of this tilted block. The western margin with the Herodotus Basin is complicated by Miocene to Present days tectonics.A NW-SE strike-slip fault trend affected considerably the whole area W and SW of the ECB.In addition a West Eratosthenes collapsed Basin opened to the West during Late Miocene(mainly Pre-Messinian).It is separated from the Herodotus Basin by a High which is the western boundary of the ECB. Consequences of these new data on the scenarios of geological evolution of the Eastern Mediterranean are discussed.
