Abstract: | The North Anatolian Fault crosses the Sea of Marmara from east to west. Tectonic features of the Sea of Marmara were studied
using multi-channel deep seismic reflection data. The northern branch of the North Anatolian Fault is active as a right lateral
strike-slip fault zone and indicates both negative and positive flower structures. The North Anatolian Fault splays into two
faults at the Sea of Marmara as a northern branch and north segment of the southern branch. The northern branch named the
Main Marmara Fault extends in a complicated manner from the north of the Kapıdağı Peninsula to westward in the Sea of Marmara.
The north segment of southern branch extends between the Gemlik and Bandırma gulfs in the south of the Sea of Marmara. In
addition, uplift areas arose by compression and a push-up style in between the Kapıdağı Peninsula and the Main Marmara Fault.
The North Anatolian Fault is characterized by a negative flower structure in basins and push-up style in uplift areas in the
Sea of Marmara. An uplift area arose between the north segment of the southern branch and the northern branch of the North
Anatolian Fault. The north segment of the southern branch of the North Anatolian Fault is a strike-slip fault and displays
a pull-apart style in the seismic reflection data. |
