“…A transition from “soft” to “hard” collision probably occurred in the early Miocene [ Ballato et al ., ]. This was associated with overthrusting of the Bitlis suture zone [ Akıncı et al ., ] and with early to middle Miocene deformation and crustal thickening identified in multiple studies across the region [e.g., Ballato et al ., ; Mouthereau et al ., ; Robertson et al ., , and references therein] (Figure d). Therefore, while further work is required to test these alternative models, the authors believe that Mio‐Pliocene crustal cooling [e.g., Axen et al ., ; Okay et al ., ] should be interpreted in this context rather than as evidence for the inception of collision.…”

“…Instead, uplift of the wGC is thought to be triggered by the initiation of Arabia‐Eurasia collision [ Allen and Armstrong , ; Vincent et al ., ]. Similar late Eocene‐early Oligocene events have been recorded farther to the east along the northern margin of the collision zone in the Talysh [ Madanipour et al ., ; Vincent et al ., ], Alborz [ Rezaeian et al ., ; Ballato et al ., ], and Kopet‐Dagh [ Robert et al ., ], and, less precisely, within the Oligocene along the southern margin of the collision zone in the Zagros [ Agard et al ., ; Fakhari et al ., ], southern Turkey [ Akıncı et al ., ; Boulton , ; Robertson et al ., ], and northern Syria [ Hardenberg and Robertson , ]. These all suggest a change in kinematic regime across a larger region than that affected by the closure of northern Neotethys.…”

The western Greater Caucasus formed by the tectonic inversion of the western strand of the Greater Caucasus Basin, a Mesozoic rift that opened at the southern margin of Laurasia. Subsidence analysis indicates that the main phase of rifting occurred during the Aalenian to Bajocian synchronous with that in the eastern Alborz and, possibly, the South Caspian Basin. Secondary episodes of subsidence during the late Tithonian to Berriasian and Hauterivian to early Aptian are tentatively linked to initial rifting within the western, and possibly eastern, Black Sea and during the late Campanian to Danian to the opening of the eastern Black Sea. Initial uplift, subaerial exposure, and sediment derivation from the western Greater Caucasus occurred at the Eocene‐Oligocene transition. Oligocene and younger sediments on the southern margin of the former basin were derived from the inverting basin and uplifted parts of its northern margin, indicating that the western Greater Caucasus Basin had closed by this time. A predominance of pollen representing a montane forest environment (dominated by Pinacean pollen) within these sediments suggests that the uplifting Caucasian hinterland had a paleoaltitude of around 2 km from early Oligocene time. The closure of the western Greater Caucasus Basin and significant uplift of the range at approximately 34 Ma is earlier than stated in many studies and needs to be incorporated into geodynamic models for the Arabia‐Eurasia region.

“…The resulting sedimentary accommodation space was infilled by siliciclastic gravity-flow deposits, sourced from the overthrusting Tauride continent; (iii) Final overthrusting by the Tauride allochthon, as documented to the NW, N and NE of the Amanos Mountains, where the Burdigalian-Langhian deep-water K. Maraş sedimentary basin was deformed and over-ridden by Tauride-related units. Similar overthrusting is seen to the N and NW of the Amanos Mountains (Yılmaz et al, 1988;Yılmaz & Gürer, 1996;Robertson et al, 2006;Gül et al, 2011;Akıncı et al, 2016); (v) Propagation of compressional deformation into Arabian foreland created up to mountain-sized folds, which are mainly SE-vergent in the north and central areas but E-vergent in the south (Figure 19).

We have carried out a several-year-long study of the Amanos Mountains, on the basis of which we present new sedimentary and structural evidence, which we combine with existing data, to produce the first comprehensive synthesis in the regional geological setting. The ca. N-Strending Amanos Mountains are located at the northwesternmost edge of the Arabian plate, near the intersection of the African and Eurasian plates. Mixed siliciclastic-carbonate sediments accumulated on the north-Gondwana margin during the Palaeozoic. Triassic rift-related sedimentation was followed by platform carbonate deposition during Jurassic-Cretaceous. Late Cretaceous was characterised by platform collapse and southward emplacement of melanges and a supra-subduction zone ophiolite. Latest Cretaceous transgressive shallow-water carbonates gave way to deeper-water deposits during Palaeocene-Eocene. Eocene southward compression, reflecting initial collision, resulted in open folding, reverse faulting and duplexing. Fluvial, lagoonal and shallow-marine carbonates accumulated during Late Oligocene(?)-Early Miocene, associated with basaltic magmatism. Intensifying collision during Mid-Miocene initiated a foreland basin that then infilled with deep-water siliciclastic gravity flows. Late Miocene-Early Pliocene compression created mountain-sized folds and thrusts, verging E in the north but SE in the south. The resulting surface uplift triggered deposition of huge alluvial outwash fans in the west. Smaller alluvial fans formed along both mountain flanks during the Pleistocene after major surface uplift ended. Pliocene-Pleistocene alluvium was tilted towards the mountain front in the west. Strike-slip/transtension along the East Anatolian Transform Fault and localised sub-horizontal Quaternary basaltic volcanism in the region reflect regional transtension during Late Pliocene-Pleistocene (<4 Ma).

Introduction The Tethyan mountain ranges stretch from northwestern Africa and western Europe to the southwest Pacific Ocean and constitute the longest continuous orogenic belt on Earth. It is an extremely fertile metallogenic belt, which includes a wide diversity of ore deposit types formed in very different geodynamic settings, which are the source of a wide range of commodities mined for the benefit of society (Janković, 1977, 1997; Richards, 2015, 2016). There are other ore deposit types in this segment of the Tethyan metallogenic belt that are not covered in this special issue, such as bauxite and Ni laterite deposits (Herrington et al., 2016), ophiolite-related chromite deposits (Çiftçi et al., 2019), sedimentary exhalative and Mississippi Valley-type deposits (Palinkaš et al., 2008; Hanilçi et al., 2019), or deposits related to surficial brine processes (Helvacı, 2019).
