@article{article_304083, title={Ophiolites and Ophiolitic Mélanges of Turkey: A Review}, journal={Türkiye Jeoloji Bülteni}, volume={56}, pages={61–114}, year={2013}, author={Yılmaz, Ali and Yılmaz, Hüseyin}, keywords={Alpine ophiolites,mélanges,pre- Alpine ophiolites,sutures}, abstract={<p style="text-align:justify;"> <span style="font-size:12px;">The aim of the presented study is to review the ophiolites and ophiolitic mélanges of Turkey   </span> <span style="font-size:12px;">and their importance for constraints on the evolution of the region. On the basis of the existing data, the  </span> <span style="font-size:12px;">ophiolitic associations of Turkey are classified into three main groups. </span> </p> <p style="text-align:justify;"> <span style="font-size:12px;">1. Group comprises pre-Alpine ophiolites and mélanges located on the southern edge of the  </span> <span style="font-size:12px;">Istanbul zone. These associations are in Pre-Jurassic age, and represent ophiolitic sequences of the Pontide  </span> <span style="font-size:12px;">Suture zone. The Karakaya complex represents pre-Alpine ophiolitic mélange and developed during the  </span> <span style="font-size:12px;">emplacement of the pre-Alpine ophiolites. The opening and closing ages and polarity of the Paleotethys  </span> <span style="font-size:12px;">is still a question. </span> </p> <p style="text-align:justify;"> <span style="font-size:12px;">2. Group can be divided into two sub-belts and they are the Northern-Northeastern and the Southern  </span> <span style="font-size:12px;">sub belt. They are allied to the North Anatolian Ophiolitic Belt (NAOB). The northern-northeastern subbelt  </span> <span style="font-size:12px;">extends from Izmir to eastward, continuing as the Ankara-Erzincan zone and as the Sevan-Akera  </span> <span style="font-size:12px;">sub-belt of the Lesser Caucasus Ophiolitic Belt (LCOB). This sub-belt directly represents the northern  </span> <span style="font-size:12px;">branch of Neotethys. The ophiolites of this sub-belt represent dismembered ophiolitic sequences and </span> <span style="font-size:12px;">take place within the Late Cretaceous melanges. The southern sub-belt begins in the Marmaris area and  </span> <span style="font-size:12px;">continues eastward to the Hadim, Aladağlar, Tecer-Divriği, Erzurum, Kağızman areas, and then on to the  </span> <span style="font-size:12px;">Vedi sub-belt of the LCOB. The ophiolitic outcrops of the Hınıs area and northeast of Lake Van, may be  </span> <span style="font-size:12px;">the southernmost products of the southern sub-belt of the NAOB associations. In the framework of age,  </span> <span style="font-size:12px;">composition, and tectonic setting ophiolites and mélanges of the southern sub-belt and northern sub belt  </span> <span style="font-size:12px;">show similar characteristic features. Therefore the southern subbelt units may be tectonically transported  </span> <span style="font-size:12px;">products of the northern sub-belt. The opening of the northern branch of Neotethys began in Triassic time  </span> <span style="font-size:12px;">in the west, in the Jurassic in the east. The closing of the northern branch of Neotethys was initiated in the  </span> <span style="font-size:12px;">Late Cretaceous and ended in pre-Middle Eocene time.  </span> </p> <p style="text-align:justify;"> <span style="font-size:12px;">3. Group is represented by the Southern and Southeastern Anatolian Ophiolitic Belt (SAOB) comprising  </span> <span style="font-size:12px;">Jurassic-Lower Cretaceous ordered ophiolitic sequences and Late Cretaceous mélanges. Opening of the southern Neotethys began in Triassic and closure began in the Late Cretaceous and ended in pre-Late  </span> <span style="font-size:12px;">Miocene.  </span> </p> <p style="text-align:justify;"> <span style="font-size:12px;">2. and 3 groups of ophiolites with mélanges are separated from one another by the Taurus Unmetamorphic  </span> <span style="font-size:12px;">Axis of the Anatolide-Tauride block These ophiolites together include Mid Ocean Ridge Basalt (MORB)  </span> <span style="font-size:12px;">and Supra-subduction zone (SSZ) type ophiolites, emplaced along double northward subduction zones in  </span> <span style="font-size:12px;">Late Cretaceous. The emplacement style for the ophiolitic units along NAOB and SAOB show a flower  </span> <span style="font-size:12px;">structure, on the basis of the presence of north- and south-facing overthrusts.  </span> </p>}, number={2}, publisher={TMMOB Jeoloji Mühendisleri Odası}
