“…However, reinterpretation of the magnetotelluric and transient electromagnetic (MT) data (Kaya, 2010) demonstrates existing of the southern branch in this area (Seyitoğlu et al, 2016) (Figure 6a). Moreover, the pull-apart nature of Gölpazarı (Gürbüz and Seyitoğlu, 2014) and Üyük basins (Figure 3) indicates that a major strike-slip branch passing through in this location. Kinematic relationship between the Gölpazarı and Bayırköy faults, and their linkage to the faults which bound the eastern margin of Yenişehir pull-apart basin form a different configuration than that of Barka and Kadinsky-Cade (1988) which suggested a linkage (Ulugergerli vd., 2007'den yeniden yorumlanmıştır).…”

“…The Gölpazarı Fault (GPF) starts around Köybaşı and its segments create Gölpazarı pull-apart basin (Gürbüz and Seyitoğlu, 2014) (Figure 3). This basin is one of the important morphological evidences unrecognized by the earlier studies that the southern branch of NAFZ is passing from this location.…”

The segment distribution of the northern branch of the North Anatolian Fault Zone (NAFZ) is well determined under the Sea of Marmara by intense seismic reflection studies. However, there is no agreement on the number of branches and their positions in the southern Marmara and western Anatolia, even if the area is not covered by the sea. In this paper, we performed morphotectonic studies with the help of the high-resolution satellite images, seismicity, and focal mechanism solutions of significant earthquakes to determine the segment distribution of the active faults accurately. Thus, the distinction of middle and southern branches of NAFZ in the southern Marmara region is established and the route of southern branch of NAFZ from Bolu to Değirmenlik (Milos) island via Bursa, Balıkesir, and İzmir is documented in detail. Besides, our results demonstrate that the hypotheses of "bend model" and "İzmir-Balıkesir Transfer Zone", which were suggested in previous publications to explain the active fault pattern in southern Marmara and western Anatolia, are not working.

“…The present day structural framework and morphology of the Marmara region is mainly characterized by NW-SE, NE-SW and E-W striking en-echelon fault systems and approximately NNE-SSW elongated tectonic domains (Emre et al, 2016;Gürer et al, 2003Gürer et al, , 2006Sözbilir et al, 2016b). In spite of the fact that the kinematic descriptions & tectonic interactions of these faults have significant importance on the understanding of the tectonic evolution of the Marmara province, there is not much paleostress data accumulated through the region yet (Bonev, Beccaletto, Robyr, & Monié, 2009;Dirik, Belindir, Özsayın, & Kutluay, 2008;Gürbüz & Seyitoğlu, 2014;Gürer et al, 2003Gürer et al, , 2006Gürer et al, , 2016Kürçer et al, 2012;Özalp, Kürçer, Özdemir, & Duman, 2016;Özden, Över, Kavak, & İnal, 2008;Sözbilir et al, 2016b;Yıldız et al, 2013). Hence, here we will give brief information about literature first, then will discuss the kinematic history of the region by merging prominent outcomes of this study and previous studies.…”

“…They also note that there is some minor NE-SW extension related normal faults and most probably associated with the local transtensional areas along the deformation zone of NAFZ. Gürbüz and Seyitoğlu (2014) is worked one of the Quaternary basins on the southern branch of NAFZ, and collect structural data along the basin margin faults. They present paleostress analysis from two stations, and document that the local paleostress axes are related with the NW-SE trending contraction and NE-SW trending extension (plots 9 on Figure 7).…”

Cenozoic convergence, collision and subsequent subduction between African and Eurasian plates are accommodating in overriding Eurasian plate both forming the Aegean extension and the North & East Anatolian fault zones. To understand the kinematic evolution of upper crust, here we provide new paleostress data from the Havran-Balıkesir Fault Zone located at the interaction area between the North Anatolian Fault Zone (NAFZ) and west Anatolian extensional structures. Paleostress reconstructions of fault-slip data reveal that three distinct deformation phases have been experienced in the region. Phase 1 is represented by leftlateral strike-slip faulting with reverse component in the pre-Pliocene period. The Phase 2 is characterized by approximately N-S trending contraction and associated E-W trending extension in Plio-Quaternary, which is spatiotemporally linked to the initiation of NAFZ through the area. The youngest deformation, Phase 3 is attributed to NE-SW trending extension and NW-SE-trending contraction commenced by the Quaternary transpressional tectonics in Southern Marmara Region. These results show that the main contraction axes have been experienced a spectacular anticlockwise rotation (from NW-SE to E-W), which is associated with; (i)the propagation geometry of the NAFZ into the region (ii)slab roll-back and retreat and tearing process on the Aegean subduction system, and (iii)the existence of inherited structures of the İzmir-Balıkesir Transfer Zone.

This paper proposes an alternative route for the southern branch of the North Anatolian Fault Zone (NAFZ) using evidence from morphotectonic features, seismology, GPS and recently published Magnetotelluric and Transient Electromagnetic (MT) data. In this new route, the southern branch connects with the main branch of the NAFZ in Bolu via the Gölpazarı pull-apart basin and Mudurnu. The slip distribution of the NAFZ as taken from GPS data indicates that the newly hypothesized route is the second most important branch of the NAFZ.
