“…The rock units in the imbricated thrust sheets range in age from Late Cretaceous to Early Miocene (Yılmaz 1993). Further to the west-southwest, the rock units of the imbrication zone are traced along the Misis-Andırın Mountain belt (Yılmaz et al 1987;Yılmaz 1990;Kelling et al 1987;Robertson et al 2004Robertson et al , 2006a. The Arabian platform comprises autochthonous and parautochthonous sedimentary units deposited since Early Paleozoic time (Fig.…”

In southeast Anatolia, there are number of tectonomagmatic units in the Kahramanmaras¸-Malatya-Elazıg˘region that are important in understanding the geological evolution of the southeast Anatolian orogenic belt during the Late Cretaceous. These are (a) metamorphic massifs, (b) ophiolites, (c) ophiolite-related metamorphics and (d) granitoids. The granitoids (i.e. Go¨ksun-Afs¸in in Kahramanmaras¸, Dog˘ans¸ehir in Malatya and Baskil in Elazıg˘) intrude all the former units in a NE-SW trending direction. The granitoid in Go¨ksun-Afs¸in (Kahramanmaras¸) region is mainly composed of granodioritic and granitic in composition. The granodiorite contains a number of amphibole-bearing mafic microgranular enclaves of different sizes, whereas the granite is intruded by numerous aplitic dikes. The granitoid rocks have typical calcalkaline geochemical features. The REE-and Ocean ridge granite-normalized multi-element patterns and tectonomagmatic discrimination diagrams, as well as biotite geochemistry suggest that the granitoids were formed in a volcanic arc setting. The K-Ar geochronology of the granitoid rocks yielded ages ranging from 85.76±3.17 to 77.49±1.91 Ma. The field, geochemical and geochronological data suggest the following Late Cretaceous tectonomagmatic scenario for southeast Anatolia. The ophiolites were formed in a suprasubduction zone tectonic setting whereas the ophiolite-related metamorphic rocks formed either during the initiation of intraoceanic subduction or late-thrusting ($90 Ma). These units were then overthrust by the Malatya-Keban platform during the progressive elimination of the southern Neotethys. Thrusting of the Malatya-Keban platform over the ophiolites and related metamorphic rocks was followed by the intrusion of the granitoids (88-85 Ma) along the Tauride active continental margin in the southern Neotethys.

“…The Central Taurides, which define the plateau's southern margin ( Fig. 1), were accreted to crustal blocks to the north starting in the Eocene (Jaffey and Robertson, 2005;Pourteau et al, 2010;Robertson et al, 1996;Şengör and Yılmaz, 1981;Şengör et al, 1984, 1985Yılmaz et al, 1997), while closure of the Neotethys Ocean to the south and associated ArabiaEurasia collision (Ballato et al, 2011;Hüsing et al, 2009;Kelling et al, 1987;Robertson, 2000;Şengör et al, 1985;Williams et al, 1995) resulted in westward "escape" of the Anatolian microplate along the North and East Anatolian faults (Dewey and Şengör, 1979;Şengör et al, 1985). Some uplift of Central Anatolia likely resulted from this plate-scale deformation, both along the southern margin prior to the Middle Miocene Robertson, 2002, 2005;Jaffey and Robertson, 2005) and at the northern margin due to strain accumulation along the broad restraining bend of the North Anatolian Fault (Yıldırım et al, 2011).…”

“…The Misis Range is a relict of the last collisional phase in the region and an olistostromic complex tectonically emplaced onto imbricated Miocene to Early Pliocene marine sediments [Kelling et al, 1987]. Subsequent left lateral strike slip faulting within this complex is included in the record of the contemporary stress field identified by earthquake activity noted below and shown in Figure 2.…”

Neotectonic deformation linking the east Anatolian and Karataş‐Osmaniye intracontinental transform fault zones in the Gulf of İskenderun, southern Turkey, deduced from paleomagnetic study of the Ceyhan‐Osmaniye volcanics

Left‐lateral strike slip along the Dead Sea Fault Zone (DSFZ) between the African and Arabian plates is partitioned into a complex set of motions at its northern extension where Arabia impinges into the Anatolian collage. As a result, the nature of the contemporary link between the east Anatolian and Dead Sea transforms is unclear. To quantify strike slip motion expressed as tectonic rotations along the inferred southwest continuation of the East Anatolian Fault Zone (EAFZ), we have investigated the paleomagnetism of young (<1 Ma) volcanics in the Adana Basin‐Gulf of İskenderun region comprising the Ceyhan‐Osmaniye volcanic suite. This volcanism is sited close to the intersection between the sinistral Karataş‐Osmaniye Fault Zone (KOFZ) and the Neotethyian Suture. Nine sites from a basaltic lava field in the vicinity of Osmaniye are entirely of normal polarity and, in the context of their very young morphologies, are assigned to the Brunhes Chron; declinations are mostly clockwise from the present field. This age assignment identifies rapid Recent (<780 ka) uplift at the head of the Gulf of İskenderun and is linked to a diversion of the Ceyhan river drainage and ongoing regional tilting. Eight sites yield a mean declination of 11.3 ± 10°, implying clockwise block rotation on Riedel‐type fractures on the northwest side of the KOFZ. Seven lavas sites from a volcanic succession near Botaş at the southwestern extension of the volcanic lineament are of reversed polarity and rotated counterclockwise by 43 ± 7° with respect to the present field. Polarity, K‐Ar, and morphological evidence indicate an assignment toward the latter part of the Matuyama Chron and identify rapid Neogene block rotation of a flake within the KOFZ. An inferred maximum slip rate of 0.6 cm/year on this fault zone is comparable with lower estimates of slip on the EAFZ and suggests that most strike slip on the DSFZ is now being partitioned to the west of the Gulf of İskenderun on a developing strike slip zone linking with the Cyprus Arc.
