“…6 and 7, sites 2-3; site 1a-b; site 11 and site 12) convincingly solves the confusion due to the lithological similarities [Sakınç et al, 1999;Yaltırak et al, 2000]. The above inferences remove any remaining doubt about the stratigraphic and structural position of both the Kirazlı and Alçıtepe formations.…”

“…This suggests that distributed deformation took place within a ~30 km-wide zone, above the NNAF fault extremity prior to its propagation all the way to the surface. The nature and offset of the deformed structures, their relation with the NAF and the timing of the onset of the fault in the Dardanelles have been questioned by various studies [Yaltırak et al, 2000;Okay et al, 2000 andLe Pichon et al, 2001;Rangin et al, 2004;Zattin et al, 2005Okay et al, 2010. We address these questions with new observations and age constraints for the Dardanelles fold system.…”

“…Controversial stratigraphy of the late Miocene -early Pliocene in the Canakkale region. Conventional stratigraphy (e.g., Görür et al, 1997;Sakınç et al, 1999;Yaltırak et al, 2000;Türkecan and Yurtsever, 2002;Çagatay et al, 2006) suggests gradual transition from the Kirazlı to the Alcıtepe formations (Messinian age in this case) capped by the Zanclean Conkbayırı Formation. In this study (middle) angular and erosional (MES) unconformities between the Alçıtepe and Kirazlı formations supported by calcareous nannoplankton biostratigraphy (Fig.…”

“…The half-anticline is 30 km long and 8 km wide with an average N45°E trend, and reaches an elevation of 444 m. The EoceneOligocene deposits (~3.75 km thick) are folded. They consist of turbidites alternating with reef limestones and calciturbidites implying a braided fluviatile -deltaic deposition environment differing from the depositional environment in Mount Ganos [Yaltırak et al, 2000].…”

“…Both features are anticlines characterized by a nearly intact dome shape, and an average trend N45°E oblique to the NAF (N70°E strike). They consist of folded sediments of essentially turbiditic nature alternating with silts, sandstones, andesitic tuffs, and basaltic lavas deposited in a pro-deltaic environment [Yaltırak et al, 2000] with a total thickness of ~5.5 km.…”

Key Points:• Structural map and geological cross-section of the Ganos-Gelibolu fold system in the Dardanelles region.• Timing, amount of shortening associated to the propagation of the North Anatolian Fault deduced from mapping and critical revision of the stratigraphy.• Reconstruction of the westward propagation of the NAF in the Dardanelles region. AbstractPropagation processes of plate-scale faults through continental lithosphere are poorly documented. The North Anatolian fault (NAF) is a continental right-lateral transform with striking evidence for propagation processes in the Marmara Sea pull-apart region. Earlier work [Armijo et al., 1999] suggests that in the Dardanelles, where the principal, northern branch of that fault (NNAF) enters into the Aegean: (1) a fold-thrust system has progressively developed above the NNAF fault tip, at the WSW corner of the Marmara Sea pull-apart. The main anticline formed there was sheared and its SW half laterally offset by ~70 km to the SW; (2) the timing of structure development appears correlated with sea-level changes associated with the Messinian Salinity Crisis (MSC). Our new description of the Dardanelles (or Ganos-Gelibolu) fold-thrust system is based on structural mapping, field observations and calcareous nannoplankton analyses to date key sedimentary units. Our results provide tight constraints on the main pulse of folding associated with propagation of the tip of the NNAF: it took place in the late Miocene to earliest Pliocene (5.60 to 5.04 Ma), before deposition of undeformed Pliocene marine sediments. The folding is mostly coeval with the MSC and accommodated several kilometers of shortening at the fault tip. After full propagation of the NNAF up to the surface, the folded structure was sheared and right-laterally offset, with an average 14 mm/yr of slip-rate during the past ~5 Myrs. A reconstruction of tectonic evolution suggests a flower structure nucleating and taking root at the tip of the fault.

Eastern Marmara region consists of three different morphotectonic units: Thrace–Kocaeli Peneplain (TKP) and Çamdağ–Akçakoca Highland (ÇAH) in the north, and Armutlu–Almacık Highland in the south of the North Anatolian Fault Zone (NAFZ). The geologic‐morphologic data and seismic profiles from the Sakarya River offshore indicate that the boundary between the TKP in the west and ÇAH in the east is a previously unrecognized major NNE–SSW‐trending strike‐slip fault zone with reverse component. The fault zone is a distinct morphotectonic corridor herein named the Adapazarı–Karasu corridor (AKC) that runs along the Sakarya River Valley and extends to its submarine canyon along the southern margin of the Black Sea in the north. It formed as a transfer fault zone between the TKP and ÇAH during the Late Miocene; the former has been experiencing extensional forces and the latter compressional forces since then. East–West‐trending segments of the NAFZ cuts the NE–SW‐trending AKC and their activity has resulted in the formation of a distinct fault‐bounded morphology, which is characterized by alternating E–W highlands and lowlands in the AKC. Furthermore, this activity has resulted in the downward motion of an ancient delta and submarine canyon of the Sakarya River in the northern block of the NAFZ below sea level so that the waters of the Black Sea invaded them. The NE–SW‐trending faults in the AKC were reactivated with the development of the NAFZ in the Late Pliocene, which then caused block motions and microseismic activities throughout the AKC.
