| Structural Features And Geologıcal Development Of The Yenısehır (Bursa) Basın In The Neotectonıc Perıod
The study area covers Seymen and Erdoğan villages, located to the west of Yenişehir (Bursa) district and Ebeköy, Köprühisar and Hayriye villages located to the east of Yenişehir district in the east of southeast of Marmara region. The geology and the neotectonics features of the study area have been examined within the scope of this research. The study area, in which the southern branches of North Anatolian Fault (NAF) is situated, comprises a Paleozoic basement belonging to Sakarya Continent, Mesozoic and Senozoic units and cover rocks. Paleozoic basement consists of Permo-Triassic Yenişehir Metamorphics Composition. Mesozoic sequence contains Middle-Upper Jurassic Bilecik Limestones with carbonate platform features. Senozoic units are made up of Middle-Upper Miocene Gemiciköy Formation and Lower-Upper Pliocene Alaylı Formation and Quaternary alluvial deposits. These units, which overlie unconformbly the older units, covers the surface area of Yenişehir Basin.
Seymen and Kovanlık fault zones, which displays many morphological characteristics of an active fault are located to the west and east of Yenişehir basin respectively. The basin is bounded at the west by Seymen fault zone which is nearly N50E direction, and at the east by Kovanlık fault zone, which is nearly N65-70E direction. The alluvial and pliocene age deposits have developed in the control of these two fault zones in the study area. The solutions of historical earthquakes and small-medium magnitude recent earthquakes in the area indicate that Seymen and Kovanlık fault zones are active faults. All these data suggest that the fault zones observed in the study area can be considered as a part of the North Anatolian Fault and Plio-Quaternary age Yenişehir basin also seem to be a pull-apart basin developed in the control of these active faults.
