摘要: Abstract The Sea of Marmara is located in the North Anatolian Fault (NAF), a major continental transform plate boundary between Eurasian and Anatolian-Aegean plates. area also under influence N-S extensional Aegean regime. 100 km-wide NAF zone region accommodates 24 mm/year dextral motion, with 70%–80% this displacement taking place along northern branch NAF, Main Marmara. main morphological elements consists ~ 1250 m-deep three subbasins two NE-trending compressional highs separating deep subbasins. other are 850-m-deep Kumburgaz Basin, ~ 400-m-deep Imrali 100–200 m-deep E-W oriented gulfs or bays. slopes connecting shelf to basins have angles ranging 6 29 degrees incised by submarine canyons marked landslides scars. accumulated up 6-km-thick sediments. They subsiding at rate 5–6 mm/year accumulating sediments rates 1–3 mm/year. morphology controlled activity complex basement structure, which various micro-continents, suture zones, Eocene-Oligocene Thrace Basin. incipient started Late Mid-Miocene. Initiation crustal extension strain localization Early Pliocene. Considering subsidence sedimentation, present day Marmara, its transtensional intervening splays developed mainly during last 2.5 Ma. This geomorphic evolution reviewed on basis published unpublished data.
