Tectonic setting of the southern Marmara Sea region: based on seismic reflection data and gravity modelling

On the basis of gravity modelling on the southern Marmara Sea shelf and conventional multichannel seismic reflection data, the tectonic setting of the region was studied. The relation of the middle strand of the North Anatolian Fault Zone with the Thrace–Eskişehir Fault Zone was examined. The southern Marmara Sea region was tectonically uplifted in the Late Pliocene. Gemlik Bay was developed during Late Pliocene–Early Pleistocene under the control of right lateral strike–slip faults along the middle strand of the North Anatolian Fault. The northwest trending Thrace–Eskişehir Fault is the second important tectonic element in this evolution.
