Abstract: The qualitative investigation of 54 grab samples and 14 gravity cores from the Saros Gulf was carriedout in order to understand the present and recent prevailing sedimantological conditions. Observations ongrab samples show that the western part of the northern shelf is covered by a sandy siliciclastic lobe.Gastropods prefer shallower (<-50 m) depths, while large bivalve shells are common within mud even at -150m water depth. Sedimentological evaluation of the gravity cores provided the occurrence of a type-1unconformity and overlying 50-130 cm thick fining/deepening upward cycle in the northern shelf as deep as -85 m water depth. Below this unconformity of at least 20 km extend, semi-consolidated salt-bearing mudoccurs while intraformational blocks and coquinites are found above. Based on the environmentalinterpretations and relating the obtained results to the previous works, this unconformity and followingsediments were assumed to be the record of Holocene transgression in the Saros Gulf.
