Özet
Ophiolites exposed in the Konya region of south-central Anatolia play an important role in understanding the distribution of Neotethyan suture zones and paleogeography in the eastern Mediterranean region. The Dipsizgöl ophiolites consist mainly of upper mantle peridotites, rare ultramafic cumulates, and microgabbro – diabase dykes that locally crosscut the peridotites. Basaltic rocks of the Dipsizgöl ophiolite and the Huğlu Unit display P-MORB composition affected by subduction-affected melts. The Huğlu Unit developed in a continental back-arc setting within the Tauride ribbon continent during the Middle-Late Triassic through Cretaceous. The Dipsizgöl ophiolite is geochemically similar to the ophiolites derived from the Pindos back-arc basin, which opened between the Dinaride–Hellenide microcontinent and the Pelagonia Platform to the west during the Late Triassic. A diabase dyke from the Dipsizgöl ophiolite revealed a Rb–Sr whole-rock isochron age of 183 ± 69 Ma. Although we take into account the possibility of errors arising from processes within the system or external factors, this data indicates that the oceanic basin existed between the Lower Triassic to the latest Lower Cretaceous. This intra-continental back-arc basin was likely part of the Southern Inner-Tauride Ocean (SITO), which constituted the eastern equivalent of the Mesozoic Pindos ocean farther west. The Hatip-Çağırbağı, Yükselen, Yunak, Çeşmelisebil and Altınekin ophiolites in the Anatolides exhibit geochemical characteristics of back-arc to fore-arc environments, and represent the remnants of the Mesozoic Northern Inner-Tauride Ocean (NITO). The U-Pb zircon dating of a shoshonitic mafic dyke that crosscuts the Altinekin ophiolitic mélange revealed a 70–85 Ma crystallization age, which is interpreted as the timing of the development of an immature volcanic arc. With the opening of the Neotethys in the late Permian, the Apulian microcontinent, which comprised the Dinaride–Hellenide–Tauride carbonate platforms, broke away from the Gondwana continent and drifted northwards. The Pindos basin was a separate seaway in Neotethys and opened within the Apulian microcontinent in the early? Triassic and closed in the Late Cretaceous–Early Paleocene.
