Neotectonic structures in the area offshore of Alaçatı, Doğanbey and Kuşadası (western Turkey): evidence of strike-slip faulting in the Aegean extensional province

About 400 km of new seismic reflection data has been acquired in the study region offshore of Alaçatı, Doğanbey, and Kuşadası, which enables investigation of the active crustal deformation in this region. The deformation onshore in western Turkey is dominated by crustal extension, and clear evidence...

Description
Summary:About 400 km of new seismic reflection data has been acquired in the study region offshore of Alaçatı, Doğanbey, and Kuşadası, which enables investigation of the active crustal deformation in this region. The deformation onshore in western Turkey is dominated by crustal extension, and clear evidence of this process is also now available from this offshore area. However, in the onshore area adjacent to this study region evidence of active right-lateral strike-slip faulting has also previously been observed. This strike-slip faulting has previously been thought only to accommodate variations in extension between adjacent normal faults. However, in the offshore area there is considerable evidence of zones of deformation, some of which may link to the strike-slip faulting onshore, suggesting that strike-slip faulting may be of greater importance in this region than previously thought.
