“…The evolution of the easternmost Mediterranean region and Turkey can be explained by the opening and closure of several oceanic basins adjacent to Gondwana and Laurasia between the Mesozoic and Early Cenozoic (Robertson et al, 2012). These are, from north to south, the Intra-Pontide Ocean, the İzmir-Ankara-Erzincan Ocean (northern Neotethys), the Inner Tauride Ocean, the southern Neotethys and the Berit Ocean (Robertson et al, 2012(Robertson et al, , 2006Parlak et al, 2009;Okay and Tüysüz, 1999;Görür et al, 1984;Robertson and Dixon, 1984;Şengör and Yılmaz, 1981).…”

With the exception of the Intra-Pontide Ocean, a widely accepted scenario for the evolution of the oceanic basins is: (a) Triassic rifting, (b) Jurassic-Early Cretaceous passive margin subsidence, (c) Late Cretaceous intraoceanic convergence/metamorphic sole formation/ supra-subduction zone ophiolite genesis and (d) latest Cretaceous emplacement onto continental margins.…”

“…The Antalya complex, including the Tekirova ophiolite, has been correlated with the Troodos ophiolite (Cyprus), the Baer-Bassit ophiolite (northern Syria) and the Kızıldağ (Hatay) ophiolite. These ophiolites originated within the southern Neotethys (Çetinkaplan et al, 2016;Robertson et al, 2012;Robertson and Waldron, 1990;Robertson andWoodcock, 1982, 1981a, b, c). The Beyşehir-Hoyran nappes farther east originated near the southern margin of the Inner Tauride Ocean and reached their position by out-of-sequence thrusting in the Late Cretaceous (Andrew and Robertson, 2002).…”

The Tauride ophiolites lie on the northern and southern flanks of an E-W-trending Tauride carbonate platform. They mainly consist of three tectonic units namely in ascending order, ophiolitic mélange, sub-ophiolitic metamorphic sole and oceanic lithospheric remnants. They were generated above intra-oceanic subduction zones and emplaced over the Tauride carbonate platform from different Neotethyan oceanic basins in the Late Cretaceous. Tauride ophiolites from west to east are described and reviewed. All are underlain by well-preserved dynamothermal metamorphic soles of varied structural thicknesses up to 500 m that have a constant structural position between ophiolitic mélange below and harzburgitic mantle tectonites above and display typical inverted metamorphic sequences from amphibolite facies above to greenschist facies below. The metamorphic soles are shown to have evolved during the initiation of subduction and emplacement processes. In the Pozantı-Karsantı area the contact between the metamorphic sole and the overlying serpentinized harzburgites is characterized by a 1.5-2-m-thick zone of sheared serpentinized harzburgitic mantle intercalated with amphibolites and cut by thick mafic dykes (7-8 m) which postdate intraoceanic metamorphism and high-temperature ductile deformation. This contact is interpreted as an intra-oceanic decoupling surface along which volcanics from the upper levels of the down-going plate were metamorphosed to amphibolite facies and accreted to the base of the hanging wall plate. The metamorphic soles and overlying ophiolitic rocks were intruded by numerous isolated post-metamorphic diabase dykes filled by island arc tholeiitic magma. Subduction initiation and roll-back processes best explain the structural and petrological relationships of Late Cretaceous ophiolite genesis, metamorphic sole formation and subsequent dyke emplacement of the Tauride ophiolites. KEY WORDS: ophiolite, metamorphic sole, dyke emplacement, roll-back, subduction initiation. INTRODUCTIONThe Tauride orogenic belts of Turkey are interpreted as representing a continental fragment that rifted from Gondwana (North Africa) during the Triassic, followed by reamalgamation and continental collision during the OligoMiocene (Karaoğlan et al., 2016) or Miocene (Okay et al., 2010). The Taurides are traditionally divided into three contiguous parts; the western, central and eastern Taurides (Özgül, 1976).Ophiolites along the Tauride belt start with the Lycian nappes to the west and end with the Divriği ophiolite to the east (Fig. 1). These ophiolites (the Lycian nappes, Antalya, Beyşehir-Hoyran nappes, Mersin, Alihoca, Pozantı-Karsantı, Pınarbaşı and Divriği) are situated either on the northern or on the southern flank of an approximately E-W trending Tauride carbonate platform axis (Juteau, 1980 (Juteau, 1980). The plutonic sections and the metamorphic soles of the Tauride ophiolites are cut by numerous isolated microgabbro-diabase and minor pyroxenite dykes at different structural levels (Robertson et al

“…How were metamorphic complexes such as the June Complex and the widespread Hamadan Phyllite generated? Our suggestion is that opening of extensional basins within continental fragments, such as in Iran and much more widely documented in Turkey (Moix et al, 2008;Robertson et al, 2012), is more widespread than recognised. These extensional basins represent weak zones in the continental crust and were subsequently preferentially deformed during the rapidly changing tectonics as convergence was transferred from Paleo-Tethys to NeoTethys in the Triassic and Jurassic (Fig.…”
