Abstract
The Sea of Marmara is located on a continental crust. The Sea of Marmara, which is a remnant of the Sarmasien period of the Miocene Sea, is an inland sea (Okay, 2007). It opens to the Black Sea with the Bosphorus and the Aegean Sea with the Dardanelles. Its surface area is 11 111 km2 (Gazioğlu, et al., 2002) and its average depth ranges from -200 to -500 m (Doğanay, 1997). At the end of the third time, and at the beginning of the fourth time, there were crumbs and crashes arising from the earth crust movements in and around, where this sea lies today (İzbırak, 1996).In the Marmara Sea, the oldest sediments were deposited as a result of the transformation of the Marmara Sea from a lacustrine environment to a marine environment with the Mediterranean Tyrenian transgression at the end of Middle Pleistocene. When the sea level in the Sea of Marmara is at the same or higher than the present day, water passage from the Black Sea has occurred. At the beginning of Late Pleistocene, as a result of a sudden drop in world sea level, the water passage from the Marmara Sea to the Mediterranean was cut and the marine sedimentation environment was replaced by lacustrine sedimentation. At the beginning of Late Pleistocene (between 64.000-59.000 BC), Mediterranean waters entered the Sea of Marmara and the Black Sea with the sudden rise of sea level (Algan, et al., 2011 ). After the transgression, the gulfs and islands in the Sea of Marmara were formed.
