Abstract

The shelf between Tekirdağ and Şarkoy, NW Marmara 

Sea, is controlled by a major fault system, the Ganos Fault

(GF), which is claimed to be the source of the 7.3

(Ms) earthquake in 1912. The effect of GF and global

sea-level changes on of the shelf between Tekirdağ and

Şarkoy was discussed on the basis of seismic-stratigraphic

data. Two main units (U1, U2) and three para-sequences

(U1a, U1b and U1c) were determined. The para-sequences

(U1b, U1c) are of fluvial origin and are mainly controlled

by the sea-level fluctuations. The sea-bottom morphology

and the thickness of the resulting seismic-stratigraphic

units must have been controlled mainly by the GF.

Moreover, the GF also controls the elevation differences

between the wave-cut terraces along the Tekirdag-Şarkoy

self and the others in the Marmara Sea.
