Özet

Tectonic features of Saros gulf which formed West Anatolian shores were investigated by means of seismic reflection and gravity methods from MTA gravity data. Saros gulf lies along the north and south blocks of North Anatolian Fault (NAF) respectively.  Seismic reflection data is used to represent the best of the Saros Gulf in 1985 and in 1988 by TPAO in the measured profiles is selected; it is interpreted in the light of current information.

As a result of these studies, the Gulf of Saros bathymetric, stratigraphyical and structural features those were different from the angle. In the Gulf of Saros strike-slipe segments NAF's control development and graben are beginning to shape in Pliocene is understood. According to the results of seismic reflection Plio-Quaternary sedimentary thickness of the Gulf of Saros in the base of approximately 150 m. is around. Evaluation data as a result of gravity with Euler deconvolution depth values obtained are seen to be compatible with the seismic results. Accordingly, the Saros has a broad in the beam and a deep structure. When we examine the formation mechanism of the Saros Gulf, the main fault line in the south of the border with slip (northern branch of NAF), the secondary fault and normal fault from the north side is understood to occur. The geometric similarity is probably depend on a secondary tensional direction in NNW-SSE which developed by the east edge of Crete and Cyprus arc.
