“…This led to the idea that the Lebanon / Anti-Lebanon mountains and Jabal Nusayriyah or Syrian Coastal Range have developed synkinematically with the left-lateral slip on the DSFZ (e.g., Westaway, 2003Westaway, , 2004Gomez et al, 2006), rather than having developed beforehand as was previously thought (e.g., Brew et al, 2001). At the same time, significant left-lateral faulting has been recognised along the Karasu Valley, from offset Pleistocene basalt flows (Yurtmen et al, 2002;Seyrek et al, 2007) and offset stream channels (Karabacak et al, 2010;Karabacak and Altunel, 2013); we suggest the name Karasu…”

The kinematics of central-southern Turkey and northwest Syria revisited

Central-southern Turkey, NW Syria, and adjacent offshore areas in the NE Mediterranean region form the boundary zone between the Turkish, African and Arabian plates. A great deal of new information has emerged in recent years regarding senses and rates of active crustal deformation in this region, but this material has not hitherto been well integrated, so the interpretations of key localities by different teams remain contradictory. We have reviewed and synthesized this evidence, combining it with new investigations targeted at key areas of uncertainty. This work has led to the inference of previously unrecognized active faults and has clarified the roles of other structures within the framework of plate motions provided by GPS studies. Roughly one third of the relative motion between the Turkish and Arabian plates is accommodated on the Misis-Kyrenia Fault Zone, which links to the study region from the Kyrenia mountain range of northern Cyprus. Much of this motion passes NNE then eastward around the northern limit of the Amanos Mountains, as previously thought, but some of it splays northeastward to link into newly-recognised normal faulting within the Amanos Mountains. The remaining two thirds of the relative motion is accommodated along the Karasu Valley; some of this component steps leftward across the Amik Basin before passing southward onto the northern Dead Sea Fault Zone (DSFZ) but much of it continues southwestward, past the city of Antakya, then into offshore structures, ultimately linking Central-southern Turkey and northwest Syria; Page 2; 30/12/2013 to the subduction zone bounding the Turkish and African plates to the southwest of Cyprus.However, some of this offshore motion continues southward, west of the Syrian coast, before linking onshore into the southern DSFZ; this component of the relative motion is indeed the main reason why the slip rate on the northern DSFZ, measured geodetically, is so much lower than that on its southern counterpart. In some parts of this region, notably in the Karasu Valley, it is now clear how the expected relative plate motion has been accommodated on active faults during much of the Quaternary: rather than constant slip rates on individual faults, quite complex changes in the partitioning of this motion on timescales of hundreds of thousands of years are indicated. However, in other parts of the region it remains unclear whether additional major active faults remain unrecognised or whether significant relative motions are accommodated by distributed deformation or on the many smaller-scale structures present.

“…The length of the Syrian Coastal Range is greater than the Ghab Valley, suggesting that uplift of the Syrian Coastal Range is not solely an isostatic response to the local extension and opening of the Ghab valley [26]. The Ghab Valley, may be viewed as a large analog to pull-apart basins that develop along the San Andreas fault within the greater transpressional context of the California Coast Range.…”

“…Ghab rift valley is developed along the northern parts of the DSFS in Syria. Brew et al (2001aBrew et al ( , 2001b consider this pull-apart basin as a deep structure opened in response to a leftstep in the DSFS during Pliocene to Holocene. It is bounded from the north and northeast by the NNE elongated Al Rouj Valley and Al Wastani Mountain.…”
