MULTI-CHANNEL MARINE SEISMIC SURVEY AND PRELIMINARY RESULTS OFF-SHORE KARABURUN RIDGE (WESTERN SIGACIK GULF-AEGEAN SEA)

Sigacik Gulf is located south of Izmir (West Anatolia), the third crowded city of Turkey. The gulf is restricted by two important ridgeson land from west to east, Karaburun Ridgeand Seferihisar Ridge, respectively. Recent geological and geophysical studies suggested that these ridgesare dominated by active strike-slip faults both on land and off- shore. This manuscript presents the results of the high resolution multi-channel seismic reflection survey which carried out onboard K. Piri Reis, research vessel of Dokuz Eylul University, off- shoreKaraburun Ridge(Aegean Sea) and surroundings in August-2005. Two main seismic units, lower unit and upper unit, were determined on seismic sections besides the active faults, buried faults and buried folds.
