Özet

The qualitative investigation of 54 grab samples and 14 gravity cores from the Saros Gulf was carried out in order to understand the present and recent prevailing sedimantological conditions. Observations on grab 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 -150 m water depth. Sedimentological evaluation of the gravity cores provided the occurrence of a type-1 unconformity 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 kin extend, semi-consolidated salt-bearing mud occurs while intrafbrmational blocks and coquinites are found above. Based on the environmental interpretations and relating the obtained results to the previous works, this unconformity and following sediments were assumed to be the record of Holocene transgression in the Saros Gulf.
