Geodynamic significance of the early triassic Karaburun granitoid (Western Turkey) for the opening history of Neo-Tethys

Öz:
Türkiye’nin Anatolid-Torid Bloğu’nun bir parçası olarak nitelendirilen Karaburun Yarımadası, Gondvana’nınkuzey kenarında çökelmiş kırıntılı ve karbonatlara ait serileri içermektedir. Erken Triyas yaşlı granitoid tarafından kesilenve Mezosoyik melanj istii ni tektonik olarak üzerleyen Paleozoyik kırıntılı seri üç alt üniteye ayrılabilir: kumtaşı-şeylardalanmasından oluşan alt kırıntılı alt-ünite, siyah çört içerikli şeyl ile kumtaşı ve konglomeradan oluşan üst kırıntılıalt-ünitesi ve Permo–Karbonifer karbonat alt-ünite. Erken Triyas yaşlı I-tipi Karaburun granitoidi, yüksek ilksel$^ {87}Sr/^ {86} Sr$ oranına (0.709021–0.709168), düşük ilksel$^ {143} Nd/^ {144} Nd$ oranına (0.512004–0.512023) ve εNd (–5.34 ile –5.70) izotopikdeğerine sahiptir. Jeokronolojik veriler granitoidin kristalizasyon (sokulum) yaşını 247.1±2.0 my (Sikitiyen) olduğunubelirtmektedir. Bu asidik magmatizma dalma-batma ile ilişkili kıtasal-yay tektonik ortam koşullarının yansıtmaktadır.Söz konusu tektonik ortam, Paleo-Tetis Okyanusu’nun güneye doğru, Gondwana altına dalması-batması sırasındaGondwana’nın kuzey kenarı boyunca gelişen kıtasal yay-arkası yırtılma ile ilişkili Neo-Tetis okyanusunun kuzeykolunun açılması şeklinde yorumlanabilir.

Neo-Tetis’in gelişim tarihi içinde erken triyas Karaburun granitoidi’nin (Batı Türkiye) jeodinamik Önemi

Öz:
The Karaburun Peninsula, which is considered part of the Anatolide-Tauride Block of Turkey, contains clasticand carbonate sequences deposited on the northern margin of Gondwana. The Palaeozoic clastic sequence, which isintruded by the Early Triassic granitoid and tectonically overlies a Mesozoic mélange sequence, can be divided into threesubunits: a lowerclastic subunit consisting of a sandstone-shale alternation, an upper clastic subunit consisting of blackchert-bearing shales, sandstone and conglomerate, and a Permo–Carboniferous carbonate subunit. h e lower TriassicKaraburun I-type granitoid has a high initial$^ {87}Sr/^ {86} Sr$ ratio (0.709021–0.709168), and low$^ {143} Nd/^ {144} Nd$ ratio (0.512004– 0.512023) and εNd (–5.34 to –5.70) isotopic values. Geochronological data indicate a crystallization (intrusion) ageof 247.1±2.0 Ma (Scythian). Geochemically, the acidic magmatism rel ects a subduction-related continental-arc basintectonic setting, which can be linked to the opening of the northern branch of Neo-Tethys as a continental back-arcrit ing basin on the northern margin of Gondwana. h is can be related to the closure through southward subduction ofthe Palaeotethys Ocean beneath Gondwana.
