Polyphased block tectonics along the North Anatolian Fault in the Tosya basin area (Turkey)

Late Cenozoic tectonics and stratigraphy of northwestern Anatolia: the effects of the North Anatolian Fault to the region

“…In the model of Chorowicz et al (1999) and Adıyaman et al (2001), it was suggested that within Anatolia there are many triangular-shaped sectors formed by the NAF, and NE-to ENE-striking late Neogene faults which branch from the central and eastern NAF (Dewey et al 1986;Barka 1992;Chorowicz et al 1995;Tatar et al 1995;Bozkurt and Koçyigit 1996;Dhont et al 1998;. The sectors constitute an escape wedge which has migrated by successive jumps from west to east, creating NE-SW-trending fault zones (Chorowicz et al 1999;Adıyaman et al 2001).…”

Preliminary slip rate estimates for the Düzce segment of the North Anatolian Fault Zone from offset geomorphic markers

“…These results open new questions about: (i) the temporal fault interactions between the Mudurnu and the Düzce faults, as an interlinked seismogenic system; (ii) the relative role of these faults in the seismic hazard of the area; (iii) the cause of the structural style along this part of the NAFZ and its inception in the plate boundary evolution. Dhont et al (1998); (6) to (9), (12) and (13) Erinc (1953), Gaudemer et al (1989), Barka and Gulen, (1989), Huber-Ferrari et al (2002) and Şengör et al (2005); (10) and (11) Irrlitz (1972), Seymen (1975), Tatar (1978), Barka, (1992), Westaway (1994 and Hubert-Ferrari et al (2002). Radiocarbon ages and associated chronologic data for sediments from the Tilki-Cicubey area.…”

“…1a). However, limited documented offset of structural or geomorphic markers exist along the 1500 km-long North Anatolian Fault Zone (NAFZ) (Dhont et al, 1998;Armijo et al, 1999;Hubert-Ferrari et al, 2002;Polonia et al, 2004;Şengör et al, 2005) (Fig. 1b).…”

Seismic velocity and Poisson’s ratio tomography of the crust beneath East Anatolia

“…The westward extrusion of the Anatolian wedge, initiated in the early Pliocene (e.g., Dhont et al, 1998;Kocyigit and Beyhan, 1998;Platzman et al, 1998;Armijo et al, 1999;Barka et al, 2000), is accompanied by anticlockwise rotation (McKenzie, 1970;Westaway, 1994;Seber et al, 1997;Reilinger et al, 2006), and is interpreted as a lateral escape of the continental lithosphere away from zones of compression (tectonic escape) to minimize topographic relief and to avoid subduction of buoyant continental material. Whether the westward motion is driven by push forces caused by topography in eastern Turkey or by pull forces caused by subduction south of the Aegean since the late Oligocene (Jolivet et al, 1994;Jolivet and Patriat, 1999) is still a matter of controversy (Bozkurt, 2001).…”
