Abstract The two main Tethyan sutures of Turkey, the İzmir-Ankara-Erzincan and Intra-Pontide sutures, are reviewed through several well-studied transects crossing suture regions. Both have formed during Early Tertiary continental collisions following northward subduction oceanic lithosphere. is represented along most its c. 2000 km length by Paleocene younger thrust, which emplace upper crustal rocks northern continent over that southern with an intervening tectonic layer Cretaceous...
Diamond occurs in ultrahigh pressure metamorphic rocks from Dabie Shan, Anhui Province, eastern China. Diamond-bearing include eclogite, gamet-pyroxenite, and jadeitite. a mineral assemblage with coesite jadeite. The diamonds diamondiferous of Shan are interpreted to be the products metamorphism undérthrust basement Yangtze continental plate during early Mesozoic, at greater than 4.0 gigapascals 900 degrees C. This interpretation is based on distribution rock units, stability field diamond,...

Late Cretaceous–Early Eocene Tethyan evolution of western Turkey is characterized by ophiolite obduction, high-pressure/low-temperature metamorphism, subduction, arc magmatism and continent–continent collision. The imprints these events in the Upper Cretaceous–Lower sedimentary record Anatolia are studied thirty-eight well-described stratigraphic sections. During Cretaceous period, consisted two continents, Pontides north Anatolide-Taurides south. These continental masses were separated...
A metamorphic core complex of latest Oligocene age crops out in the Kazdağ mountain range northwest Turkey. The footwall consists gneiss, amphibolite and marble metamorphosed at 5 ± 1 kbar 640° 50 °C. average muscovite biotite Rb/Sr ages from gneisses are 19 Ma 22 Ma, respectively, imply high temperature metamorphism during times. hangingwall is made up an unmetamorphosed Lower Tertiary oceanic accretionary melange with Upper Cretaceous eclogite lenses. separated by extensional ductile shear...
The Tekirdağ depression within the Marmara Sea in Mediterranean region is an active, rhomb‐shaped strike‐slip basin along North Anatolian fault with a floor at water depth of −1150 m. New multichannel seismic reflection data and on‐land geological studies indicate that forming releasing bend filled syntransform sediments Pliocene‐Quaternary age. bounded on one side by other subparallel normal fault, which forms steep submarine slope. In cross section strongly asymmetric thickness strata...

Abstract We review the Palaeozoic-Early Mesozoic evolution of Eastern Mediterranean-Balkan region with special reference to Anatolia, and provide new isotopic data on Palaeozoic magmatic metamorphic rocks. The pre-Alpide involves episodic growth Laurussia by accretion oceanic terranes Gondwana-derived microcontinents. Terrane accretion, associated deformation, magmatism regional metamorphism, took place in Late Ordovician-Early Silurian, Carboniferous, Triassic-Early Jurassic Mid-Jurassic....
Abstract The Pontides in northern Turkey constituted part of the southern active margin Eurasia during Mesozoic. In Early Cretaceous, a large submarine turbidite fan covered most Central Pontides. New U‐Pb detrital zircon data imply that major source turbidites was East European Craton‐Scythian Platform north. This implies there no thoroughgoing Black Sea basin between and Craton Cretaceous. Lower Cretaceous are bounded south by metamorphic area, Pontide Supercomplex (CPS). geological...
